                    DANAHER CORPORATION EXTENDS TENDER OFFER

              FOR LIFSCHULTZ INDUSTRIES, INC. THROUGH JUNE 20, 2001
________________________________________________________________________________


  Washington, D.C., June 20, 2001 - Danaher Corporation (NYSE:DHR) announced
today that it is extending its tender offer for outstanding shares of Lifschultz
Industries, Inc. (NASDAQ:LIFF) common stock from the prior expiration date of
midnight on Tuesday, June 19, 2001 to midnight on Wednesday, June 20, 2001.
Accordingly, the tender offer and withdrawal rights will expire at 12:00
midnight, New York City time, on June 20, 2001, unless Danaher further extends
the tender offer. According to a preliminary count by the depositary for the
offer, there were tendered and not withdrawn 948,161 shares as of 12:00 midnight
on June 19, 2000 (including 17,486 shares listed on notices of guaranteed
delivery received by the depositary), representing approximately 84.02% of the
shares of Lifschultz common stock currently outstanding.

  Danaher is extending the offer so that more than 90 percent of the shares of
Lifschultz common stock may be validly tendered and not withdrawn prior to the
expiration of the offer. If that occurs, Danaher will be able to use the
expedited procedures available under Delaware law for a merger with a 90
percent-owned subsidiary.

  Lifschultz engages, through its wholly-owned subsidiary, Hart Scientific, Inc.
("Hart"), and Hart's wholly-owned subsidiary, Calorimetry Sciences Corporation,
in the development, manufacturing, and marketing of scientific and industrial
calorimetry instrumentation and industrial temperature calibration equipment.

  Danaher Corporation is a leading manufacturer of Process/Environmental
Controls and Tools and Components. (www.danaher.com)
