NEWS RELEASE

     LOVELAND, COLORADO, SEPTEMBER 11, 1995 (NASDAQ-HACH) Hach Company announced
today that its Board of Directors has unanimously rejected Lawter
International's unsolicited merger proposal to acquire all Hach Company shares
not owned by Lawter for $21.00 per share.  In declining Lawter's proposal,
Hach's Board noted that the Hach family controls approximately 42% of the
Company's outstanding shares and that, as a practical matter, any transaction
would require the support of the family shareholders.

     Mrs. Kathryn Hach-Darrow, Hach's Chairman, stated: "After careful
consideration, Hach's Board of Directors has concluded  Hach is not for sale.
We believe that the interests of the Company's shareholders, employees and
customers  will be best served by the Company remaining independent and pursuing
its long term strategy for growth."

     Hach Company is a leading manufacturer and distributor of laboratory
instruments, process analyzers, test kits and analytical reagents which are used
to analyze the chemical content and other properties of water and other aqueous
solutions.
