NOTE 1:  In the opinion of management, the accompanying unaudited condensed 
consolidated financial statements contain all the adjustments necessary for a 
fair presentation of the financial position of the Company and the results of 
operations for the interim periods presented herein.  All such adjustments 
are of a normal recurring nature.  Results of operations for the current 
unaudited interim period are not necessarily indicative of the results which 
may be expected for the entire fiscal year.  All significant inter-company 
transactions and accounts have been eliminated.

While the Company believes that the disclosures presented are adequate to 
make the information not misleading, it is suggested that these condensed 
consolidated financial statements be read in conjunction with the 
consolidated financial statements and notes to the consolidated financial 
statements included in the Annual Report on Form 10K for the year ended July 
25, 1997.

NOTE 2:  Certain reclassifications have been made to the prior period's 
financial statements to conform to the current period's presentation.

NOTE 3:  Inventories are valued at the lower of cost or market, principally 
on the last-in, first-out (LIFO) basis.  The composition of inventories is as 
follows:

NOTE 6:  On May 21, 1998, the Board of Directors declared a quarterly cash 
dividend of $.05 per share, payable July 1, 1998 to shareholders of record on 
June 12, 1998.

NOTE 7:  ACCOUNTING PRONOUNCEMENTS.  Statement of Financial Accounting 
Standards No. 130 "Report Comprehensive Income", and Statement of Financial 
Accounting Standards No. 131 "Disclosure about Segments of an Enterprise and 
Related Information", have been issued by the Financial Accounting Standards 
Board.  The Company does not expect the adoption of these statements to be 
material to the consolidated financial statements.

NOTE 8:  On September 17, 1997, the Company acquired the remaining 
approximately 82 percent of Geomation, Inc., Golden, Colorado.  The 
acquisition required approximately $929,000 in cash and the issuance of 
318,853 shares of the Company's common stock.  The transaction also included 
an earn-out provision, which depending upon the performance of Geomation 
through July 1998, may require the payment of up to approximately $250,000 of 
additional cash and the issuance of additional shares of the Company's common 
stock with a market value of up to approximately $750,000.  The transaction 
was accounted for as a purchase with resulting intangibles of approximately 
$2,093,000 being amortized over periods ranging from 3 to 15 years.  The 
transaction also included approximately $302,000 of "purchased R&D" which was 
expensed in the first quarter of fiscal 1998.

On December 29, 1997, the Company acquired 100 percent of the STIP Siepmann 
and Teutscher GmbH (STIP), of Gross Umstadt, Germany.  The share purchase of 
STIP required cash of approximately $230,000.  STIP produces a broad line of 
process monitoring instrumentation designed specifically for wastewater 
treatment applications.  In a separate and simultaneous transaction, the 
Company also acquired 100 percent of the technology covering the products 
produced by STIP. This technology was acquired from a partnership owned by 
Messrs. Siepmann and Teutscher for cash of approximately $1,690,000.  The 
acquisition includes an earn-out from January 1, 1998 through December 31, 
1999.  Based on the performance (with respect to sales and profitability of 
STIP) during the earn-out period, the amount of the earn-out payment could 
range up to $1.7 million. The two transactions are being accounted for as 
purchases with the resulting intangibles of approximately $1,690,000 being 
amortized over periods ranging from 7 to 15 years.

The following unaudited pro forma financial information sets forth the 
results of operations of Isco, Inc. as if the acquisition of Geomation and 
STIP had occurred on July 27, 1996:

On March 31, 1998, the Company and AMJ Equipment Corporation, Lakeland, 
Florida, completed the formation of Advanced Flow Technologies, Partnership 
Ltd., (AFTCO) with each owning 50 percent of AFTCO.  The Company's investment 
of $1.5 million will be accounted for under the equity method.  The cost in 
excess of net assets acquired of approximately $750,000 will be amortized on 
a straight-line basis over 10 years.  AFTCO designs, manufactures, and 
markets electromagnetic closed pipe flow meters.

NOTE 9:  On January 22, 1998, Zellweger Analytics, Inc. ("Zellweger") filed 
an action against the Company in the United States District Court for the 
Southern District of Texas in Galveston, Texas, alleging patent and trade 
dress infringement involving the EZ TOC product of the Company.  Zellweger 
sought to enjoin the Company from making, using, and selling the EZ TOC and 
seeks unspecified damages.  On January 23, 1998, the Court issued a 
preliminary injunction, expiring July 8, 1998, enjoining the Company's 
production, use, and sales of EZ TOC.  Zellweger was required to post a 
$500,000 bond for the injunction to become operative.

The Company has filed a Motion to Dismiss the action.  On February 12, 1998, 
Zellweger posted the bond to make the injunction operative.  Management does 
not believe that the number of EZ TOC products manufactured and sold to date 
would subject it to any material damage claims.  The Company intends to 
vigorously defend the charges and believes that it will ultimately prevail in 
this matter.

ITEM 2.
          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS

THE FOLLOWING MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS CONTAIN TREND ANALYSIS AND TOGETHER FORWARD-LOOKING
STATEMENTS WITHIN THE MEANING OF SECTION 27A OF THE SECURITIES ACT OF 1933, AS
AMENDED, AND SECTION 21E OF THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED.
ACTUAL RESULTS COULD DIFFER MATERIALLY FROM THOSE PROJECTED IN THE FORWARD-
LOOKING STATEMENTS WITHIN THIS DOCUMENT.

SALES ANALYSIS AND REVIEW.

Sales for the three-month and nine-month periods, ended April 24, 1998, were 
$13,246,000 and $35,131,000, respectively.  Included, in the periods under 
review were Geomation sales of $886,000 and $1,523,000, respectively, and 
STIP Siepmann and Teutscher, GmbH (STIP) sales of $941,000 for the 
three-month period.  For the periods under review, sales were 29 percent and 
20 percent higher than for the same periods one year earlier.  Sales of the 
Company's core products (wastewater samplers, flow meters, and liquid 
chromatography products) for the three months were 14 percent higher, while 
for the same period, sales of other products which include:  syringe pumps, 
supercritical fluid extraction (SFE) products, STIP products, Geomation 
products, and process monitoring products, were 110 percent higher.  During 
the three months, sales of wastewater samplers and flow meters recovered and 
contributed to the sales growth of the core products.  Also, the delivery of 
the new chromatography products for the combinatorial chemistry market during 
this period contributed to the sales growth of the core products.  For the 
nine months, sales of the core products were up 10 percent, while for the 
same period, sales of other products were up 66 percent.

The Company's three-month and nine-month U.S. sales were up 16 percent and 
13 percent, respectively, when compared with the same periods last year. 
Excluding Geomation and STIP sales, the Company's U.S. sales for the same 
periods were up 14 percent and 11 percent, respectively.  The U.S. sales of 
the core products for the same periods were up 14 percent and six percent, 
respectively.  The U.S. sales of the other products, including Geomation and 
STIP products, for the same periods were up 56 percent and 72 percent, 
respectively.  The realignment of the Company's U.S. sales force along 
product lines, recognizing specialized market expertise of sales staff, 
continues to be successful for delivering sales for both new and non-core 
products

The Company's three-month and nine-month international sales were up 62 
percent and 39 percent, respectively, when compared with the same periods 
last year. Excluding Geomation and STIP sales, the Company's international 
sales for the same periods were up four percent and 14 percent, respectively. 
 International sales of the core products for the same periods were up 16 
percent and 25 percent, respectively.  During the three months, wastewater 
samplers and chromatography products provided the growth in the international 
sales of the core products.  International sales of the other products, 
including Geomation and STIP products, for the same periods were up 157 
percent and 60 percent, respectively.  Management believes that initiatives 
begun last fiscal year to provide more sales and marketing support for the 
Company's

                                       8
<PAGE>

international dealers continue to be successful and that the Company has 
large opportunities to gain international market share.

Net orders for the three months and nine months were $12 million and $34 
million, respectively.  Orders were 16 percent and nine percent higher, 
respectively, for the periods compared with the same periods one year ago. 
During the current year's reporting periods, orders received by Geomation 
were $354,000 and $1,517,000, respectively, and orders received by STIP were 
$599,000 for the three months ended April 24, 1998.  At April 24, 1998, the 
Company's order backlog, including $42,000 and $605,000, respectively, of 
Geomation and STIP order backlogs, was $4 million, which is flat when 
compared with the beginning of the fiscal year, prior to the acquisition of 
Geomation and STIP.  The Company's order backlog normally includes 
approximately $1 million of orders from contractors requesting delayed 
delivery of three to 12 months and orders from OEM customers with scheduled 
deliveries over a period of up to one year.  The Company expects to deliver 
nearly all of the remaining orders in the normal order backlog under its 
regular delivery schedule of three days to three weeks.

OPERATING INCOME ANALYSIS AND REVIEW.

For the three months and nine months ended April 24, 1998, the Company, 
including Geomation and STIP operations, had consolidated operating losses of 
$51,000 and $257,000, respectively.  This compares with operating income of 
$239,000 and operating loss of $223,000, respectively, for the same periods 
last year.  For the same periods, the gross margin percentage declined 3.7 
percent and was flat, respectively, when compared with the same periods last 
year.  The decline in gross margin during the recent three-month period is 
the result of increased international sales of the Company's core products 
where dealer discounts are a reduction of the selling price, thus reducing 
"net sales", the base for this calculation.

Selling, general, and administrative expenses (on a consolidated basis) 
increased 20 percent and 14 percent, respectively, for the three months and 
nine months of fiscal 1998 when compared with the same periods last year.  
The growth in selling expenses was primarily the result of:  increased 
personnel expenses (salaries and benefits) which included nine additional 
employees along with increased travel expenses to better serve the customers; 
the planned increase in more focused advertising; increased commissions on 
higher sales volume by manufacturers' representatives and distributors; and 
the amortization of intangibles arising out of acquisitions.  In the general 
and administrative area, the increase included: increased personnel expenses 
which included three additional employees; higher continuing education 
expenses arising out of management's effort to upgrade the computer 
utilization skills of employees, company-wide, in preparation for 
implementing the enterprise resource planning (ERP) system.  The Company 
incurred significant expenses related to the implementation of the ERP 
system.  These increased expenditures will continue into the second fiscal 
quarter of 1999.

Research and engineering expenses (on a consolidated basis) increased 
57 percent and 45 percent, respectively, for the three months and nine months 
of fiscal 1998 when compared with the same periods last year.  The growth in 
expenses for the nine-month period includes approximately $302,000 of 
"purchased R&D" acquired in the Geomation acquisition.  Management's focus on 
getting new products to market faster and ensuring that the new products more 
adequately meet the needs of the customer has been the driver for the growth 
in engineering expenses.  There has been a small increase in staff along with 
a significant increase in expenditures during the recently completed three 
months for outside professional services and consultants to achieve the 
accelerated pace of product introduction.

- ------------------------------------------------------------------------------------------------------------------------------
</TABLE>

The underlying reasons for the changes in operating income were discussed in 
the previous section.  The Company's investment income for fiscal year 1998 
to-date is lower than the same period last year due to the liquidation of 
investments to fund the acquisition of Geomation, Inc., STIP, and the 
investment in Advanced Flow Technologies, Partnership Ltd. (see Recent 
Developments section), to improve the Company's computer technological 
capabilities, and to make progress payments related to the expansion and 
renovation of the Company's Superior Street facility.

For the three months ended April 24, 1998, the Company had an income tax 
benefit compared with an effective income tax rate of 16.3 percent for the 
same period last year.  That change is the result of lower earnings and a R&D 
tax credit resulting from higher levels of qualified research and engineering 
spending during the period.  Those same causes account for the decline in 
effective income tax rate to 1.5 percent for the nine months of fiscal 1998 
from 11.3 percent for the same period last year.

FINANCIAL CONDITION AND LIQUIDITY.

At April 24, 1998, the Company's working capital was nearly $23 million.  The 
Company has in place, with its primary U.S. commercial bank, an unused, 
unsecured $3 million line of credit.

The Company, after many years of being debt-free, now has both short-term and 
long-term debt on its balance sheet.  The share purchase of STIP included 
retaining on STIP's balance sheet the existing bank loan, with the Company 
guaranteeing bank borrowings up to DM2.5 million (US$1.4 million).  Also 
remaining, in place, were two long-term economic development loans totaling 
DM1.25 million (US$684,000) from the State of Hessen, Germany.

During the recent three-month period, the Company's inventories (excluding 
the Geomation and STIP inventories of $1,767,000) declined $505,000.  
Excluding Geomation and STIP, during the recent three-month period the 
Company's accounts payable declined $279,000.

                                       10

<PAGE>

The Company will continue to have significant cash needs during the remainder 
of calendar year 1998.  During this time frame, management expects to 
complete the expansion and renovation of the Superior Street facility and the 
acquisition of significantly more efficient production machinery, and 
complete the installation and implementation of the (ERP) system.

The Company, in 1995, began the process of evaluating its options with regard 
to dealing with the millennium (Y2K) issue and its effect on the Company's 
computer systems.  In 1996, the Company determined that replacing its aging 
purchased and home-grown software with technologically current software would 
improve operational efficiency and as a by-product resolve the Y2K problem. 
Early in fiscal 1998, the Company selected BaaN software as its ERP system 
which is scheduled to go on line at the beginning of the second quarter of 
fiscal 1999.  The cost of the  BaaN software along with consultation costs 
and other interfaced software is being capitalized while internal 
implementation costs are being expensed currently.  The total cost of the 
project is expected to be approximately $2.5 million including an estimated 
$465,000 to be expensed as incurred.  Management does not expect Y2K costs 
relating to systems other than ERP or to the software in the Company's 
products to be significant.

RECENT DEVELOPMENTS.

Management believes that the December 29, 1997 acquisition of STIP Siepmann 
and Teutscher GmbH and the related process monitoring instrumentation 
technologies will enhance significantly the Company's existing presence in 
the wastewater treatment market.  The Company, as the U.S. and Canadian 
distributor of STIP products, now will be able to provide additional high 
quality and innovative products to its U.S. customers to improve their 
wastewater treatment processes and reduce their operating costs.

On March 31,1998, the Company and AMJ Equipment Corporation, Lakeland, 
Florida, completed the formation of Advanced Flow Technologies, Partnership 
Ltd., (AFTCO) with each owning 50 percent of AFTCO.  AFTCO designs, 
manufactures, and markets electromagnetic closed-pipe flow meters.  The 
Company will be the distribution channel for AFTCO products into the 
wastewater treatment market. Management believes these products fill an 
important need of the Company's customers and at the same time leverages the 
capacity of its existing distribution channel.

Management believes that the Asian monetary crisis will have a small negative 
effect upon sales of the Company in the near-term.  However, it believes that 
in the long-term the Company must grow its presence in that region.  This 
will be accomplished by providing increased sales and marketing support for 
its key dealer relationships in the region.

INFLATION.

The effect of inflation on the costs of the Company and its ability to pass 
on cost increases in the form of increased prices is dependent upon market 
conditions and the competitive environment.  The general level of inflation 
in the U.S. economy has been relatively low for the past several years and 
has not, to date, had a significant effect on the Company.

ITEM 1. Legal Proceedings.

A. On January 22, 1998, Zellweger Analytics, Inc. ("Zellweger") filed an

   The Company has filed a Motion to Dismiss the action.  On February 12, 1998,
   Zellweger posted the bond to make the injunction operative.  Management does
   not believe that the number of EZ TOC products manufactured and sold to date
   would subject it to any material damage claims.  The Company intends to
