COMPANY PRESS RELEASE

FERROFLUIDICS ANNOUNCES SALE OF CRYSTAL
PULLER BUSINESS

NASHUA, N.H.--(BUSINESS WIRE)--Sept. 23, 1998--Ferrofluidics Corporation
(NASDAQ:FERO-NEWS) today announced the sale of the business, intellectual
property, and certain inventory, fixed assets and tooling of its Systems
Division to Kayex, a division of General Signal Technology Corporation, for
$10,800,000 in cash.

Under the terms of the agreement, Kayex will have the right to design, market,
manufacture, and sell Ferrofluidic(R) crystal growing systems worldwide for all
future industrial requirements. It is also anticipated that a number of
Ferrofluidics Systems Division employees will be offered employment by Kayex.
Ferrofluidics will continue to honor and complete existing orders and warranty
responsibilities, and will retain all liabilities of the Systems Division.

Paul F. Avery, Jr., Chairman and Chief Executive Officer of Ferrofluidics,
stated "Our divestiture of the Systems business is consistent with the recently
announced refocusing of the Company back to its Core Technologies. The cash
received will permit the Company to repay essentially all of its short term
debt, and will thus result in substantial interest savings going forward."

This press release contains forward-looking statements within the meaning of the
federal securities laws. There are certain factors that could cause actual
results to differ materially from those anticipated by the statements made
above. For additional information concerning these and other important factors
which may cause the Company's actual results to differ materially from
expectations and underlying assumptions, please refer to the reports filed by
the Company with the Securities and Exchange Commission.

Ferrofluidics is the pioneer and world leader in ferrofluidic technology.
Founded in 1968 and based in Nashua, New Hampshire, Ferrofluidics has
established technical support facilities in the United States, Germany, the
