         PERKINELMER ANNOUNCES Q2 2003 RESULTS

         -        GAAP EPS FROM CONTINUING OPERATIONS OF $.08 PER SHARE

         -        OPERATING MARGIN EXPANSION OF 350 BASIS POINTS

         -        $37M OPERATING CASH FLOW IN Q2 03; $61M YEAR-TO-DATE

BOSTON - PerkinElmer, Inc. (NYSE: PKI) today announced second quarter 2003 GAAP
earnings per share from continuing operations of $.08 on revenue of $377.1
million, compared to GAAP earnings per share from continuing operations of $.05
and revenue of $383.1 million in the second quarter of 2002. The second quarter
of 2003 results reflect intangibles amortization of $7.0 million, or
approximately $.04 per share. Second quarter 2003 results also include a benefit
of $.01 per share from restructuring credits. Second quarter 2003 earnings are
at the upper end of the Company's previous estimate for the quarter of $.05 to
$.08 per share on a GAAP basis.

Revenue from continuing operations in the second quarter of 2003 was $377.1
million, down 2% from the same period of 2002. Growth of 8% in Optoelectronics
revenue during the second quarter of 2003 was offset by a revenue decline of 3%
in Life and Analytical Sciences and a decline in Fluid Sciences revenue of 12%
from the 2002 quarter.

GAAP operating margins during the second quarter of 2003 expanded 350 basis
points to 8% from 4.5% for the same period of 2002. Selling, general and
administrative expenses for the second quarter of 2003 were reduced by $15.4
million from the 2002 quarter, reflecting the benefits from the Life and
Analytical Sciences integration and other productivity actions.

The Company generated operating cash flow of $36.8 million in the second quarter
of 2003, an improvement of $25.2 million over the same period in 2002. For the
first six months of 2003, operating cash flow was $60.9 million. During the
second quarter of 2003, the Company reduced working capital by $34.3 million
through improved accounts receivable collections and inventory management. Total
cash and equivalents were $299.5 million at the end of the second quarter and
included $154.9 million held in escrow to retire the Company's remaining zero
coupon convertible debentures, which the Company has called for redemption on
August 7, 2003. At the end of the second quarter of 2003, the Company's debt,
net of cash and equivalents, was reduced by $29.5 million.

"We were pleased with our progress in driving cash flow and profitability
growth. The integration of our Life and Analytical Sciences unit is ahead of
schedule and will result in a stronger business, better positioned to serve our
global customers. Also, we continue to make progress on new product
introductions and building our service business," said Gregory L. Summe,
Chairman and CEO of the Company.

During the second quarter of 2003, the Company divested its entertainment
lighting business which had been previously reported as discontinued operations.
This transaction resulted in a loss on sale of ($1.7) million, or ($.01) per
share net of tax, which was reported as a loss from the disposition of
discontinued operations for the second quarter of 2003. Net earnings on a GAAP
basis for the second quarter of 2003 were $.07 per share comprised of $.08
earnings per share from continuing operations and a loss of ($.01) per share
from the disposition of discontinued operations. The Company reported a net loss
for the second quarter of 2002 of ($.07) per share which was comprised of $.05
earnings per share from continuing operations, a ($.03) per share loss from
discontinued operations and a ($.09) loss per share from the disposition of
discontinued operations.

Financial overview by reporting segment:

Beginning this quarter, the Company has presented financial information related
to its Life Sciences and Analytical Instruments segments on a combined basis as
Life and Analytical Sciences. This is pursuant to the Company's plans, announced
in the fourth quarter of 2002, to integrate the two businesses, and reflects the
current structure of the Company.

LIFE AND ANALYTICAL SCIENCES reported revenue of $246.0 million for the second
quarter of 2003, down 3% compared to revenue of $252.9 million for the second
quarter of 2002. During the second quarter of 2003, the Company reported revenue
growth in reagents, consumables and service which was more than offset by lower
instruments sales compared to the second quarter of 2002. By market segment, the
Company experienced growth in revenue during the second quarter of 2003 in its
genetic screening and environmental and chemical businesses, while sales into
the biopharma markets were down year over year. The segment's GAAP operating
profit for the second quarter of 2003 was $20.7 million versus $12.9 million in
the same period of 2002. As a percentage of sales, operating profit for the
second quarter of 2003 and 2002 was 8.4% and 5.1%, respectively. The results for
each of the second quarters of 2003 and 2002 include intangibles amortization of
$6.5 million.

OPTOELECTRONICS reported revenue of $89.4 million for the second quarter of
2003, an increase of 8% from revenue of $82.8 million for the second quarter of
2002. Growth across most major product lines drove the increase in revenues
during the quarter, due to new product introductions and continued end market
growth. The segment's GAAP operating profit was $11.1 million for the second
quarter of 2003 versus an operating profit of $4.8 million for the comparable
period in 2002. As a percentage of sales, operating profit for the second
quarter of 2003 and 2002 was 12.4% and 5.8%, respectively.

FLUID SCIENCES reported revenue of $41.7 million for the second quarter of 2003,
representing a decline of 12% compared to revenue of $47.4 million for the
second quarter of 2002. The decline in revenue was largely attributable to
continued softness in

the aerospace and semiconductor end markets. The segment's GAAP operating profit
for the second quarter of 2003 was $3.1 million versus $3.9 million in the
second quarter of 2002.

"We are seeing good market acceptance for our new products, and are beginning to
see positive trends in certain end markets," added Summe. "With good progress in
cost productivity, we believe we should be able to deliver full year 2003 GAAP
earnings per share of $.37 to $.43, which includes $.15 of intangibles
amortization," concluded Summe.
