                         Preliminary Proxy Materials
                     Filed October 18 and November 14, 2005
                     File No. 1-15695
                     Letter dated November 18, 2005

Gentlemen:

         On behalf of our client, Avitar, Inc. ("Avitar" or the "Company"), we
are responding to the comments contained in the letter dated November 18, 2005
(the "Comment Letter") and we are also providing marked copies of the revised
Preliminary Proxy Statement with a view toward facilitating your review. Our
references in this letter are to the headings and comment numbers used in the
Comment Letter. (Please note that the Company has moved back its Annual Meeting
date to January 4, 2006 and its Record Date for the Meeting to November 23,
2005.)

Purposes of the Reverse Stock Split
Comment 1.

The Company revised the first paragraph of this section to disclose the price as
of the most recent practical date.

Terms of September 2005 Private Placement
Comment No. 2

Despite the fact that $1 million of the consideration for the $3 million Notes
has not yet been paid to the Company, we believe that the registration of the
shares underlying the Notes and Warrants is appropriate at this time, based upon
Section 3S of the March 1999 telephone interpretations. As stated in that
Section:
"In a PIPE transaction (private-investment, public-equity), the staff will not
object if a company registers the resale of securities prior to their issuance
if the company has completed a Section 4(2)-exempt sale of the securities (or in
the case of convertible securities, of the convertible security itself) to the
investor, and the investor is at market risk at the time of filing of the resale
registration statement. The investor must be irrevocably bound to purchase a set
number of securities for a set purchase price that is not based on market price
or a fluctuating ratio, either at the time of effectiveness of the resale
registration statement or at any subsequent date. When a company attempts to
register for resale shares of common stock underlying unissued, convertible
securities, the staff's PIPEs analysis applies to the convertible security, not
to the underlying common stock. There can be no conditions to closing that are
within an investor's control or that an investor can cause not to be satisfied.
For example, closing conditions in capital formation transactions relating to
the market price of the company's securities or the investor's satisfactory
completion of its due diligence on the company are unacceptable conditions. The
closing of the private placement of the unissued securities must occur within a
short time after the effectiveness of the resale registration statement."

Pricipal Effects of the Reverse Stock Split
Comment No. 3

     The Company  expanded its  disclosure  in the Table in the  Sub-Section  of
Proposal No. 2 entitled  "Principal  Effects of the Reverse Stock Split - Number
of Shares of Common  Stock and  Corporate  Matters."  Specifically,  the Company
inserted  additional  information in the first column as to the number of shares
underlying the Notes based on the closing price as of the most recent  practical
date and the extent of the current shortage of authorized  shares. In the second
column,  there is a line item  disclosing  the  number of shares  that  would be
issued for the Notes after the reverse stock split.

The Company acknowledges that:

o    the Company is responsible  for the adequacy and accuracy of the disclosure
     in the filing;

o    staff  comments or changes to disclosure  in response to staff  comments do
     not  foreclose  the  Commission  from taking any action with respect to the
     filing; and

o    the Company may not assert  staff  comments as a defense in any  proceeding
     initiated by the Commission or any person under the federal securities laws
     of the United States.

Please call the undersigned at (212) 925-2800 if you have any questions.

                                     Sincerely,


                                     Eugene M. Cronin
