Sales for the quarter ended June 30, 1996 of $31,176 increased 16.3%
over sales for the second quarter of 1995.  Year-to-date 1996 sales
through June have increased 20.0% over their 1995 level.  The sales
increase was realized across most product lines.  Sales of capital
equipment represent 58% of year-to-date sales.  Sales for 1996 include
sales of Western Filter, acquired in October 1995, but do not include
any sales from Desalination Systems, Inc. (DESAL).  The previously
announced merger with DESAL was completed in July 1996.  

Gross Margin

The gross margin for the second quarter of 1996 was 41.5% versus 44.6%
for the corresponding period in 1995.  The gross margin for the six
months ended June 30 was 41.2% in 1996 and 44.5% in 1995.  The reduction
in gross margin was due to a less favorable sales mix, more aggressive
pricing in certain product lines, and some effect of higher material
costs.  Sales in 1996 include order backlog acquired from Western Filter
in October 1995, which was at lower gross margins than other Osmonics
products.

Operating Expenses

Operating expenses decreased from 32.1% of sales in the second quarter
of 1995 to 31.1% in the second quarter of 1996, and from 31.6% of sales
in the first half of 1995 to 29.3% of sales in the first half of 1996. 
The rate of growth in operating expense slowed to 11.5%, compared to the
sales growth rate of 20.0%.  The aggressive expansion in sales and
marketing efforts during the prior two years is now producing results,
and recent investments in office automation are also showing good
returns in higher productivity.  

Other Income

Other income increased by $101 from the first half of 1995 to the first
half of 1996.  The increase included $715 of gain on the sale of
investments and $640 of gain on the sale of land.  The usefulness of the
land as a future facility site for the Company was impaired by a county
road expansion.  

Income Taxes

The effective tax rate for the six months ended June 30, 1996 was 31.0%
based on the forecast for the full year.  This compares to 30.5% in the
corresponding period of 1995.                  

Net Income

Net income for the quarter ended June 30, 1996 was $2,813, up 5.3% from
$2,671 in the corresponding quarter last year.  Net income per common
share for the quarter was $0.22 versus $0.21 a year ago.  Year-to-date
net income was $5,975, up 9.2% from $5,471 in 1995.  Net income per
common share year-to-date was $0.47 in 1996 versus $0.43 in 1995.  

Liquidity and Capital Resources

As of June 30, 1996, the Company had cash, cash equivalents and
marketable securities of $23,067 versus $30,668 at December 31, 1995. 
This reduction in cash and marketable securities is primarily the result
of investments of $8,497 in new facilities and equipment.  The current
ratio was 3.1 at June 30, 1996, as compared to 2.9 at year-end 1995. 

The Company believes that its current cash and investments position, its
cash flow from operations, and amounts available from bank credit will
be adequate to meet its anticipated cash needs for working capital,
capital expenditures, and potential acquisitions during the foreseeable
future.

Stock Option Plans

The Company has elected to continue accounting for stock options in
accordance with APB 25 as provided by Statement of Financial Accounting
Standards (SFAS) No. 123 "Accounting for Stock-Based Compensation."
