FOR IMMEDIATE RELEASE
22 April 2004





                      PERKINELMER ANNOUNCES Q1 2004 RESULTS

- -     10% REVENUE GROWTH

- -     GAAP EPS OF $.10; THREEFOLD INCREASE OVER Q1 03


BOSTON - PerkinElmer, Inc. (NYSE: PKI), a global leader in health sciences and
other advanced technology markets, today announced GAAP earnings per share of
$.10 from continuing operations on revenue of $393.5 million for the first
quarter ended March 28, 2004. The first quarter 2004 results include intangibles
amortization of $7.1 million, or approximately $.04 per share. The Company
reported earnings per share from continuing operations excluding intangibles
amortization of $.14, which exceeded by $.01 the Thomson First Call(TM)
consensus earnings per share estimate for the first quarter of 2004, and was at
the high end of the Company's forecasted range for the quarter. Total GAAP net
income for the first quarter of 2004 was $13.3 million, compared to $2.4 million
for the first quarter of 2003.

Revenue in the first quarter of 2004 was $393.5 million, an increase of 10% from
the first quarter of 2003, driven by revenue growth in all segments. The
comparative increase in revenue by segment was comprised of growth of 7% in Life
and Analytical Sciences, 4% in Optoelectronics, and 34% in Fluid Sciences.
Foreign exchange rate fluctuations increased total reported revenue by
approximately 5% in the first quarter of 2004.

GAAP operating margin during the first quarter of 2004 increased to 7.0%, up 160
basis points from 5.4% for the first quarter of 2003. First quarter 2004
operating margin excluding intangibles amortization was 8.8% compared to 7.4%
for the first quarter of 2003, driven by higher revenue, cost productivity and
quality improvements. The first quarter 2004 operating profit included a $1.2
million pre-tax charge related to the impairment of a non-strategic product line
in Optoelectronics, that the Company will close later in 2004.

The Company generated operating cash flow of $26.6 million in the first quarter
of 2004. Free cash flow, defined as operating cash flow of $26.6 million less
capital expenditures of $3.3 million, was $23.3 million for the first quarter of
2004. During the first quarter of 2004, the Company reduced long-term debt by
$45.0 million. Total debt at the end of the first quarter of 2004 was $504.3
million, down by approximately $256.0 million compared to the first quarter of
2003. Total debt net of cash and cash equivalents of $165.5 million was $338.9
million at the end of the first quarter of 2004, representing a decrease of
$137.2 million from the end of the first quarter of 2003.

"We were pleased to deliver revenue growth across all three businesses,
significant operating margin expansion and excellent cash flow in our first
quarter of 2004," said Gregory L. Summe, Chairman and CEO of the Company. "With
our improved cost structure and strengthened balance sheet, we are increasing
our focus on driving revenue growth," added Summe.

Financial overview by reporting segment:

LIFE AND ANALYTICAL SCIENCES reported revenue of $249.2 million for the first
quarter of 2004, up 7% from $232.2 million in the first quarter of 2003. This
was generated by revenue growth in all businesses: BioPharma, Genetic Screening,
Environmental and Chemical, and the Company's OneSource (TM) service business.
By product category, instruments revenue was up 8%, reagents and consumables
revenue increased 5%, and service revenue increased 10% during the first quarter
of 2004 compared to the first quarter of 2003.

The segment's GAAP operating profit for the first quarter of 2004 was $16.0
million versus $11.6 million for the same period of 2003. As a percentage of
sales, operating profit for the first quarter of 2004 increased to 6.4% compared
to 5.0% for the first quarter of 2003. The operating profit for the first
quarters of 2004 and 2003 included intangibles amortization of $6.6 million and
$6.5 million, respectively.

OPTOELECTRONICS reported revenue of $86.7 million for the first quarter of 2004,
an increase of 4% from revenue of $83.3 million in the first quarter of 2003.
Revenue growth in our medical and biotech imaging business, and growth in
specialty lighting revenue was partially offset by softness in certain sensors
end markets during the quarter compared to the first quarter of 2003.

The segment's GAAP operating profit was $9.4 million for the first quarter of
2004 versus an operating profit of $8.7 million for the comparable period of
2003. As a percentage of sales, operating profit for the first quarter of 2004
and 2003 was 10.9% and 10.4%, respectively. The operating profit for each of the
first quarters of 2004 and 2003 included intangibles amortization of $.3
million.

FLUID SCIENCES reported revenue of $57.5 million for the first quarter of 2004,
up 34% from revenue of $42.9 million in the first quarter of 2003. Strong growth
in semiconductor and aerospace revenue drove the increase during the quarter
compared to the same period of 2003.

The segment's GAAP operating profit for the first quarter of 2004 was $8.3
million, versus $2.4 million in the first quarter of 2003. As a percentage of
sales, operating profit for the first quarter of 2004 and 2003 was 14.5% and
5.5%, respectively. The operating profit for the first quarter of 2004 and 2003
included intangibles amortization of $.2 million and $.4 million, respectively.

"During the quarter we saw continued gradual strengthening in our end markets,"
continued Summe. "We remain focused on our customer excellence initiatives and
acceleration of new product introductions to drive revenue growth, while
delivering our financial commitments," added Summe.

For the second quarter of 2004, the Company projects EPS from continuing
operations between $.14 and $.17 on a GAAP basis, including the negative impact
of intangibles amortization of $.04 per share. Excluding the impact of
intangibles amortization, the Company projects EPS from continuing operations
between $.18 and $.21 for the second quarter of 2004.

USE OF NON-GAAP FINANCIAL MEASURES

In addition to financial measures prepared in accordance with generally accepted
accounting principles (GAAP), this press release also contains non-GAAP
financial measures of earnings per share and operating margin, in each case
excluding amortization of acquisition-related intangible assets. We exclude the
amortization of acquisition-related intangibles in calculating these non-GAAP
measures because such amortization is outside of our normal operations. We
believe that the inclusion of these non-GAAP financial measures in this press
release helps investors to gain a meaningful understanding of our core operating
results and future prospects, consistent with how management measures and
forecasts the company's performance, especially when comparing such results to
previous periods or forecasts. PerkinElmer's management uses these non-GAAP
measures, in addition to GAAP financial measures, as the basis for measuring the
company's core operating performance and comparing such performance to that of
prior periods and to the performance of our competitors. Such measures are also
used by management in their financial and operating decision-making.

This press release also contains a non-GAAP measure of free cash flow. We define
free cash flow as our net cash provided by operating activities minus our
capital expenditures. We use free cash flow, and ratios based on this measure,
to conduct and evaluate our business and, specifically, to determine incentive
compensation, to allocate resources to debt repayment and for cash investing and
financing activities. Therefore, we believe that these measures may be similarly
useful and informative to investors.

The non-GAAP financial measures included in this press release are not meant to
be considered superior to or a substitute for results of operations prepared in
accordance with GAAP. In addition, the non-GAAP financial measures included in
this press release may be different from, and therefore may not be comparable
to, similar measures used by other companies. Reconciliations of the non-GAAP
financial measures used in this press release to the most directly comparable
GAAP financial measures are set forth in the text of, and the accompanying
exhibits, to this press release.
