Item 1.  Business.

The Company

     Millipore Corporation was incorporated under the laws of Massachusetts
on May 3, 1954.  Millipore and its subsidiaries operate in a single business
segment, the analysis, identification and purification of fluids using
separations technology.  Business segment information is discussed in Note M
to the Millipore Corporation Consolidated Financial Statements (the
"Financial Statements") included in the Millipore Corporation Annual Report
to Shareholders for the year ended December 31, 1993 (the "Annual Report"),
which note is hereby incorporated herein by reference.  Unless the context
otherwise requires, the terms "Millipore" or the "Company" mean Millipore
Corporation and its subsidiaries.

     On November 11, 1993, Millipore announced that its Board of Directors
had approved a plan to focus the Company on its membrane business and to
divest operations of its Instrumentation Divisions (the Waters Chromatography
business and the non-membrane bioscience instrument business).

     The description of Millipore's business contained herein treats both the
Waters Chromatography Business and the non-membrane bioscience business (the
"Instrumentation Divisions") as discontinued operations.  These Divisions
with separate product lines with separate customers are accounted for as
discontinued operations.  The Company expects to realize a net gain in 1994
upon the disposition of these businesses.  Operations of the discontinued
Instrumentation Divisions subsequent to November 11, 1993 are set forth in
the Company's Balance Sheet and are not material to its financial position;
operations prior to that date are included in the Company's 1993 Consolidated
Statement of Income.  For a description of Millipore's business which
includes no discontinued operations reference is made to the Company's Annual
Report on Form 10-K for the year ended December 31, 1992.

     Millipore is a leader in the field of membrane separations technology.
The Company develops, manufactures and sells products which are used
primarily for the analysis and purification of fluids.  The Company's
products are based on a variety of membranes and certain other technologies
and effect separations, principally through physical and chemical methods.
Millipore is an integrated multinational manufacturer of these products.
During 1993, approximately 62% of Millipore's net sales were made to
customers outside the Americas.  For financial information concerning foreign
and domestic operations and export sales, see Note M to the Financial
Statements.


Products and Technologies

     For analytical applications, the Company's products are used to gain
knowledge about a molecule, compound or micro-organism by detecting,
identifying and quantifying the relevant components of a sample.  For
purification applications, the Company's products are used in manufacturing
and research operations to isolate and purify specific components or to
remove contaminants.
                           Page 2


     The principal separation technologies utilized by the Company are based
on membrane filters, and certain chemistries, resins and enzyme immunoassays.
Membranes are used to filter either the wanted or the unwanted particulate,
bacterial, molecular or viral entities from fluids, or concentrate and retain
such entities (in the fluid) for further processing.  Some of the Company's
newer membrane materials also use affinity, ion-exchange or electrical charge
mechanisms for separation.

     Both analytical and purification products incorporate membrane and other
technologies.  The Company's products include disc and cartridge filters and
housings of various sizes and configurations, filter-based test kits and
precision pumps and other ancillary equipment and supplies.

     The Company has more than 3,000 products.  Most of the Company's
products are listed in its catalogs and are sold as standard items, systems
or devices.  For special applications, the Company assembles custom products,
usually based upon standard modules and components.  In certain instances,
the Company also designs and engineers process systems specifically for the
customer.

Customers and Markets

     The Company's continuing operations sells its products primarily to
customers in the following markets: pharmaceutical/biotechnology,
microelectronics, chemical and food and beverage companies; government,
university and private research and testing laboratories; and health care and
medical facilities.  Within each of these markets, the Company focuses its
sales efforts upon those segments where customers have specific requirements
which can be satisfied by the Company's products.

     Pharmaceutical/Biotechnology Industry.  The Company's products are used
by the pharmaceutical/biotechnology industry in sterilization, including
virus reduction, and sterility testing of products such as antibiotics,
vaccines, vitamins and protein solutions;  concentration and fractionation of
biological molecules such as vaccines and blood products; cell harvesting;
isolation and purification of compounds from complex mixtures and the
purification of water for laboratory use.  The Company's membrane products
also play an important role in the development of new drugs, particularly
with respect to the mechanism through which they act.  In addition, Millipore
has developed and is developing products for biopharmaceutical applications
in order to meet the separations requirements of the biotechnology industry.

     Microelectronics Industry.  The microelectronics industry uses the
Company's products to purify the liquids and gases used in the manufacturing
processes of semiconductors and other microelectronics components, by
removing particles and unwanted contaminating molecules.

     Chemical Industry.  This industry uses the Company's products for
purification of reagent grade chemicals, for monitoring in the industrial
workplace and of waste streams and in the purification of water for
laboratory use.
                           Page 3

     Food and Beverage Industry.  The Company's products are widely used by
the food and beverage industry in quality control and process applications
principally to monitor for microbiological contamination; to remove bacteria
and yeast from products such as wine and beer, in order to prevent spoilage,
and in producing pure water for laboratory use.

     Universities and Government Agencies.  Universities, government and
private and corporate research and testing laboratories, environmental
science laboratories and regulatory agencies purchase a wide range of the
Company's products.  Typical applications include: purification of proteins;
cell culture, structure studies and interactions; concentration of biological
molecules; fractionation of complex molecular mixtures; and collection of
microorganisms.  The Company's water purification products are used
extensively by these organizations to prepare high purity water for sensitive
assays and the preparation of tissue culture media.

     Health Care and Medical Research.  Customers in this field include
hospitals, clinical laboratories, medical schools and medical research
institutions who use the Company's products to filter particulate
and bacterial contaminants which may be present in intravenous solutions, and
its water purification products to produce high purity water.


Sales and Marketing

     The Company sells its products within the United States primarily to end
users through its own direct sales force. The Company sells its products in
foreign markets through the sales forces of its subsidiaries and branches
located in more than 25 major industrialized and developing countries as well
as through independent distributors in other parts of the world.  During
1993, the Company's marketing, sales and service forces consisted of
approximately 360 employees in the United States and 520 employees abroad.

     The Company's marketing efforts focus on application development for
existing products and on new and differentiated products for other existing,
newly-identified and proposed customer uses.  The Company seeks to educate
customers as to the variety of analytical and purification problems which may
be addressed by its products and to adapt its products and technologies to
separations problems identified by customers.

     The Company believes that its technical support services are important
to its marketing efforts.  These services include assistance in defining the
customer's needs, evaluating alternative solutions, designing a specific
system to perform the desired separation and training users.


Research and Development

     In its role as a pioneer of membrane separations Millipore has
traditionally placed heavy emphasis on research and development.  Research
and development activities include the extension and enhancement of existing
separations technologies to respond to new applications, the development of
                           Page 4

new membranes, and the upgrading of membrane based systems to afford the user
greater purification capabilities.  Research and development efforts also
identify new separations applications to which disposable separations devices
would be responsive, and develop new configurations into which membrane and
ion exchange separations media can be fabricated to efficiently respond to
the applications identified.  Instruments, hardware, and accessories are also
developed to incorporate membranes, modules and devices into total
separations systems.  Introduction of new applications frequently requires
considerable market development prior to the generation of revenues.
Millipore performs substantially all of its own research and development and
does not provide material amounts of research services for others.
Millipore's research and development expenses in 1991, 1992 and 1993 with
respect to continuing operations were, $32,633,000, $32,953,000 and
$34,952,000 respectively.

     When it believes it to be in its long-term interests, the Company will
license newly developed technology from unaffiliated third parties and/or
will acquire exclusive distribution rights with respect thereto.


Competition

     The Company's continuing operations face intense competition in all of
its markets.  The Company believes that its principal competitors include
Pall Corporation, Barnstead Thermolyne Corporation, Sartorius GmbH, and
Gelman, Inc.  Certain of the Company's competitors are larger and have
greater resources than the Company.  However, the Company believes that it
offers a broader line of products, making use of a wider range of separations
technologies and addressing a broader range of applications than any single
competitor.

     While price is an important factor, the Company competes primarily on
the basis of technical expertise, product quality and responsiveness to
customer needs, including service and technical support.


Acquisitions, Restructuring, and Divestitures

     On November 11, 1993 Millipore announced that its Board of Directors had
approved a plan to divest its Instrumentation Division (the Waters
Chromatography and non-membrane bioscience businesses) in order to focus the
Company on its membrane business.  The Waters Chromatography business was
acquired in 1980.  Growth in the analytical instrument market has been
limited in the past few years.  In the years 1986-1988 the Company expanded
its MilliGen division in order to extend its analytical and chemical
capabilities into the bio-instrumentation and chemicals field.  In 1990 this
business was consolidated into Millipore's then existing businesses, in order
to achieve better focus and meaningful economics.  The Company believes that
the divestiture of its chromatography business along with that of its non-
membrane bioscience business, will enable Millipore to better serve its
membrane customers, improve operating performance and increase shareholder
value.  It is anticipated that the divestiture of the Instrumentation
                           Page 5

Divisions will be completed in the first half of 1994 and is anticipated to
result in a net gain.

     At the time of the 1990 consolidation of MilliGen, the Company took
certain other actions to improve profitability, these measures in total
resulted in a non-recurring charge in the fourth quarter of 1990 amounting to
$34,750,000.  The Company took a further charge, with respect to the
restructuring of its Waters Chromatography Division, of $13,000,000 in the
first quarter of 1993.

     In the five-year period prior to its November 11, 1993 announcement
concerning the sale of its Waters Chromatography and non-membrane bioscience
business, the Company undertook a number of initiatives to expand its
business into new markets within the field of analysis and purification.  The
Company has made several small, strategic acquisitions to accelerate
technology and market development in its several divisions.  These included
the acquisition of the Bio Image division of Kodak in 1989, Extrel
Corporation in February of 1992, and Immunosystems Incorporated in July of
1992.

     In November of 1989, the Company sold its process water division for
approximately $54,000,000 in cash.  Included in the transaction were the
worldwide facilities and equipment and other assets for developing,
manufacturing and marketing that division's complete line of water
purification products, other than its laboratory scale water business.  Also
included were the Company's 18 service deionization branches located
throughout the continental United States.  This transaction is the subject of
litigation brought by Eastern Enterprises (see "Legal Proceedings").

Other Information

     In April, 1988, the Company adopted a shareholder rights plan (the
"Rights Plan") and declared a dividend to its shareholders of the right to
purchase (a "Right"), for each share of Millipore Common Stock owned, one
additional share of Millipore Common Stock at a price of $160 for each share.
The Rights Plan is designed to protect Millipore's shareholders from attempts
by others to acquire Millipore on terms or by using tactics that could deny
all shareholders the opportunity to realize the full value of their
investment.  The Rights will be exercisable only if a person or group of
affiliated or associated persons acquires beneficial ownership of 20% or more
of the outstanding shares of the Company Common Stock or commences a tender
or exchange offer that would result in a person or group owning 20% or more
of the outstanding Common Stock.  In such event, or in the event that
Millipore is subsequently acquired in a merger or other business combination,
each Right will entitle its holder to purchase, at the then current exercise
price, shares of the common stock of the surviving company having a value
equal to twice the exercise price.

     Millipore has been granted a number of patents and licenses and has
other patent applications pending both in the United States and abroad.
While these patents and licenses are viewed as valuable assets, Millipore's
patent position is not of material importance to its operations.
Millipore also owns a number of trademarks, the most significant being
"Millipore."
                           Page 6

     Millipore's products are made from a wide variety of raw materials which
are generally available in quantity from alternate sources of supply; as a
result, Millipore is not substantially dependent upon any single supplier.

     Millipore's business is neither seasonal nor dependent upon a single or
limited group of customers.

     Bringing the Company's facilities into compliance with federal, state
and local laws regulating the discharge of materials into the environment or
otherwise relating to the protection of the environment has not, to date, had
a material effect upon Millipore's capital expenditures, earnings or
competitive position.  (See "Legal Proceedings.")

     As of December 31, 1993, Millipore's continuing operations employed
3,664 persons worldwide, of whom 1,938 were employed in the United States and
1,726 overseas.

  businesses.

     In addition to the above properties, Millipore has entered into a long
term lease for premises abutting its Bedford facility.  This lease makes
75,000 square feet of building available to Millipore and contains rights of
first refusal and options with respect to the purchase of the premises by
Millipore.  During 1988 Millipore entered into a 10-year lease for a building
of 130,000 square feet located in Burlington, Massachusetts, approximately 5
miles from its Bedford headquarters.  This lease contains a single 5-year
extension option.  In 1991, the Company entered into two long term lease
arrangements.  The first was a sublease of a 130,000 square foot office
                          Page 10

building located in Marlborough, Massachusetts.  This lease expires at the
end of 1995 and Millipore has obtained from the owner an option to lease
these premises for an additional five years.  This facility is being used as
the consolidated headquarters for all the Company's U. S. sales and support
operations.  It is anticipated that the Company will vacate these premises in
1994 and will not exercise its renewal option.  The second lease arrangement
is a 15-year lease with renewal options for an aggregate of 20 years, as well
as a purchase option covering a 134,000 square foot building which is
adjacent to the Company's Bedford facility and will be used for expansion
purposes, initially the consolidation of the Company's Process System
Division (part of the Membrane Process Group).

     In addition to its foregoing properties, Millipore currently leases
various manufacturing, sales, warehouse, and administrative facilities
throughout the world.  Such leases expire at different times through 2017.
The rented space aggregate is approximately 1,050,000 square feet and cost
was approximately $8,068,000 in 1993.  No single lease, in the opinion of
Millipore, is material to its operations.

     Millipore is of the opinion that all the facilities owned or leased by
it are well maintained, appropriately insured, in good operating condition
and suitable for their present uses.


Item 3.  Legal Proceedings.

     Millipore has been sued in the Superior Court for Middlesex County,
Massachusetts by Eastern Enterprises and its subsidiary, Ionpure
Technologies, Inc. ("Ionpure"), alleging misrepresentations made in
conjunction with the sale by Millipore of its Process Water Division to
Ionpure in November of 1989.  The Company believes it has adequate and
complete defenses to this litigation and intends to vigorously defend the
action.  Although the Company is unable to predict with certainty the outcome
of the lawsuit, its ultimate disposition is not expected to have a material
adverse effect on Millipore's financial condition.

     Millipore has been notified in nine instances that the United States
Environmental Protection Agency ("EPA") has determined that a release or a
substantial threat of a release of hazardous substances (a "Release") as
defined in Section 101 of the Comprehensive Environmental Response
Compensation and Liability Act of 1980 ("CERCLA") as amended by the Superfund
Amendments and Reauthorization Act of 1986 (SARA) (the so-called "Superfund"
law) has occurred at certain sites to which chemical wastes generated by the
manufacturing operations of Millipore or one of its divisions may have been
sent.  These notifications typically also allege that Millipore may be a
responsible party under CERCLA with respect to any remedial action needed to
control or prevent any such Release.  Under CERCLA the EPA may undertake
remedial action in response to a Release and responsible parties may by
liable, without regard to fault or negligence, for costs incurred.  As a
result it is possible, although highly unlikely given the large number and
size of financially solvent corporations participating at each site who have
been similarly notified, that the Company might be liable for all of the
                           Page 11

costs incurred in such a cleanup.  In each instance Millipore knows that it
is only one of many companies and entities which received such notification
and who may likewise be held liable for any such remedial costs.  In 1992,
the EPA unexpectedly proposed settlements for several of these sites.  Based
on those proposed settlements and all other information available to
management, the Company recorded a provision of $5,800,000 against cost of
sales which, in management's best estimate, when combined with previously
established reserves, will be sufficient to satisfy all known claims by the
EPA.  In seven separate instances involving a total of ten such sites; the
Company has entered into consent decrees; paid approximately $13.9 million;
and received partial releases.  The aggregate of any future potential
liabilities is not expected to have a material adverse effect on Millipore's
financial condition.

     For purposes of complying with the amendments to the rules governing
Form S-8 (effective July 13, 1990) under the Securities Act of 1933, the
undersigned registrant hereby undertakes as follows, which undertaking shall
be incorporated by reference into registrant's Registration Statements on
Form S-8 Nos.: 2-72124; 2-85698; 2-91432; 2-97280; 33-37319; 33-37323 and 33-

          Insofar as indemnification for liabilities arising under the
     Securities Act of 1933 (The "Act") may be permitted to directors,
     officers and controlling persons of the registrant pursuant to the
     foregoing provisions, or otherwise, the registrant has been advised that
     in the opinion of the Securities and Exchange commission such
     indemnification is against public policy as expressed in the Securities
     Act of 1933 and is, therefore, unenforceable.  In the event that a claim
     for indemnification against such liabilities (other than the payment by
     the registrant of expenses incurred or paid by a director, officer or
     controlling person of the registrant in the successful defense of any
     action, suit or proceeding) is asserted by such director, officer or
     controlling person in connection with the securities being registered,
     the registrant will, unless in the opinion of its counsel the matter has
                             Page 14    

     been settled by controlling precedent, submit to a court of appropriate
     jurisdiction the question whether such indemnification by it is against
     public policy as expressed in the Act and will be governed by the final
     adjudication of such issue.
