     capital stock of Altamira $400,000 in cash, issued 125,000
     shares of Common Stock and agreed to make additional cash
     payments equal to 5%, subject to possible adjustment, of the
     net sales of Altamira for each of five periods - the first
     period is December 1, 2006 through June 30, 2007, the next
     three are to be each of the years ending June 30, 2008, June
     30, 2009 and June 30, 2010 and the fifth period is to be July
     1, 2010 through November 30, 2010.

     Altamira's principal customers are universities, government
     laboratories, and chemical and petrochemical companies.  The
     instruments which are customizable to the customers'
     specifications, are sold on a direct basis.


                              4



     In conjunction with the acquisition of Altamira, management of
     the Company, with the assistance of an independent valuation
     firm, valued the tangible and intangible assets acquired.
     Assets identified through this valuation process included
     goodwill, customer relationships, non-compete agreements, and
     certain technology, trade names and trade marks.  The carrying
     amounts of goodwill and other intangible assets are presented
     in "Note 8.  Goodwill and Other Intangible Assets" which
     represent the preliminary valuations performed in conjunction
     with the acquisition.  In addition, other fair market value
     adjustments were made in conjunction with the acquisition,
     which primarily include adjustments to property and equipment,
     and inventory.  The Company anticipates that an election will
     be made to treat the acquisition of Altamira stock as a
     purchase of assets for tax purposes.  If the election is not
     made, a deferred tax liability of approximately $325,000 would
     have to be recorded along with a corresponding increase to
     goodwill.

     The acquisition was recorded under the purchase method of
     accounting.  The preliminary net purchase price has been
     allocated to assets acquired and liabilities assumed based on
     the estimated fair market value at the date of the acquisition
     of Altamira.  The preliminary allocation of the net purchase
     price is as follows:

     Current Assets                    $ 734,000
     Property and Equipment              140,300
     Non-current Assets                   25,100
     Negative Goodwill                 (  91,500)
     Other Intangible Assets             639,000 *
     Current Liabilities               ( 561,900)
                                       __________
     Preliminary Net Purchase Price    $ 885,000
                                       ==========

     *  Of the $639,000 of acquired other intangible assets,
     $237,000 was assigned to customer relationships with a
     weighted-average estimated useful life of 10 years, $300,000
     was assigned to technology including trade names and trade
     marks with a useful life of 5 years, and $102,000 was assigned
     to a non-compete agreement with a useful life of 5 years.  The
     amounts assigned to the customer relationships are being
     amortized on an accelerated (declining balance) method and the
     other intangibles are being amortized on a straight line basis.

 3.  Line of Business and Concentrations:

 As a result of the acquisition of Altamira, the Company now views
 its operations as principally two segments: the manufacturing and
 marketing of standard benchtop laboratory equipment for research in
 university, hospital and industrial laboratories sold primarily
 through laboratory equipment distributors ("laboratory equipment
 operations"), and the manufacturing and marketing of custom-made
 catalyst research instruments for research in universities,
 government laboratories, and chemical and pretrochemical companies
 sold on a direct basis ("catalyst research instruments
 operations").  Substantially all of the management and employees of
 Altamira were retained subsequent to the acquisition.

 Segment information is reported as follows:

     (1) Approximately 70% and 75% of net sales for the laboratory
     equipment operations for the three month periods ended December
     31, 2006 and 2005, respectively, were derived from the
     Company's main product, the Vortex-Genie 2(R) mixer, excluding
     accessories, and approximately 71% for the laboratory equipment
     operations for each of the six month periods ended December 31,
     2006 and 2005.  In addition, three of the customers for the
     laboratory equipment operations accounted in the aggregate for
     28% and 46% of total net sales of laboratory equipment
     operations for the three month periods ended December 31, 2006
     and 2005, respectively, and 31% and 49% of total net sales for
     the six month periods ended December 31, 2006 and 2005,
     respectively.

     The Company's consolidated export sales (principally Europe and
     Asia) were approximately $599,900 and $434,000 for the three
     month periods ended December 31, 2006 and 2005, respectively,

 5.  Earnings per common share:

     Basic earnings per common share are computed by dividing net
     income by the weighted-average number of shares outstanding.
     Diluted earnings per common share include the dilutive effect
     of stock options and a warrant which was exercised at the end
     of September, 2005.

     Earnings per common share was computed as follows:

 6.  Comprehensive Income:

     There was no significant difference between net income and
     comprehensive income for the three and six month periods ended
     December 31, 2006 and 2005.


 7.   Stock-Based Compensation Plans:

     The Company maintains an Incentive Stock Option Plan which
     through the fiscal year ended June 30, 2006 the grants were
     accounted for under the recognition and measurement principles
     of APB Opinion No. 25, "Accounting for Stock Issued to
     Employees," and related Interpretations. Under this method, no
     stock-based compensation costs were reflected in net income, as
     all options granted under those plans had an exercise price
     equal to the fair market value of the underlying common stock
     on the date of grant.  The following table illustrates the
     effect on net income and earnings per share if the Company had
     applied the fair value recognition provisions of FASB Statement
     No. 123(R), "Accounting for Stock-Based Compensation," to
     stock-based employee compensation in the prior period:

     Any stock-based compensation transaction subsequent to June 30,
     2006 is to be accounted for using Statement of Financial
     Accounting Standards No. 123(R). This statement, issued on
     December 16, 2004, by the Financial Accounting Standards Board,
     requires compensation costs related to stock-based payment
     transactions to be recognized commencing with the first
     reporting period in our fiscal year ending June 30, 2007. With
     limited exceptions, the amount of compensation cost is measured
     based on the grant-date fair value of the equity or liability
     instruments issued. In addition, liability awards will be
     measured each reporting period. Compensation costs are
     recognized over the period that an employee provides service in
     exchange for the award.  Statement 123(R) replaces FASB
     Statement No. 123, Accounting for Stock-Based Compensation, and
     supercedes APB Opinion No. 25, accounting for Stock Issued to
     Employees. The Company did not incur any stock-based
     compensation costs for the three and six months ended December
     30, 2006.

 8.   Goodwill and Other Intangible Assets

     In conjunction with the acquisition of Altamira, management of
     the Company, with the assistance of an independent valuation
     firm, valued the tangible and intangible assets acquired.
     Assets identified through this valuation process included
     customer relationships, technology which encompasses trade
     names, trade marks, and licenses, and non-compete agreements.
     The valuation resulted in negative goodwill of approximately
     $91,500.  However, the acquisition's stock purchase agreement
     provides for contingent future payments based on net sales
     subject to certain limits, which are expected to be earned and
     paid and the negative goodwill is eventually expected to be
     fully eliminated.  Management estimates that the acquisition of
     Altamira will ultimately result in goodwill of approximately
     $300,000 to $400,000.  As of December 31, 2006 the negative
     goodwill, which has been classified as a deferred
     credit, was reduced to $72,700 as a result of additional
     contingent consideration earned.

     In accordance with Statement of Financial Accounting Standards
     No. 142, "Goodwill and Other Intangible Assets,", goodwill and
     other intangible assets are tested for impairment on an annual
     basis, or earlier if indicators of impairment exist.  As of
     December 31, 2006, the Company determined that there were no
     current indicators of impairment.  In assessing the
     recoverability of goodwill and purchased intangible assets,
     management must make assumptions regarding estimated future
     cash flows and other factors to determine the fair value of the
     respective assets.  It is reasonably possible that these
     estimates, or their related assumptions, may change in the
     future, in which we may be required to record impairment
     charges for these assets.

     The Company's amortizable other intangible assets are amortized
     using straight line and accelerated amortization methods based
     on expected benefits derived from each intangible asset.

     The components of purchased intangible assets as of December
     31, 2006 were as follows:

                                      Gross       Accum-      Net

                                      ========    =======     ========

     Total amortization expense related to intangible assets was
     $17,200 and $20,200 for the three and six months ended December
     31, 2006 and $1,600 and $3,100 for the three and six months
     ended December 31, 2005.  As of December 31, 2006, estimated
     future amortization expense related to intangible assets is
     $78,400 for the remainder of fiscal 2007, $146,800 for fiscal
     2008, $132,000 for fiscal 2009, $122,300 for fiscal 2010,
     $100,800 for fiscal 2011, $55,200 for fiscal 2012 and $32,200
     thereafter.

 Liquidity and Capital Resources

 Cash and cash equivalents increased by $65,000 to $292,700 as of
 December 31, 2006 from $227,700 as of June 30, 2006.

 Net cash provided by operating activities was $156,900 for the six
 month period of the current fiscal year as compared to $182,800 in
 the comparative period for 2005, mainly the result of higher
 balances of accounts receivable, partially offset by higher
 inventories and accrued expenses. Cash used in investing activities
 was $91,900 for the current period as compared to $197,400 for the
 six months ended December 31, 2005.  The Company used net cash of
 $346,500 in connection with the acquisition of Altamira, for which
 redemptions of investment securities amounting to $275,700 were
 effected, with the remaining cash utilized from operations.

 On September 29, 2006, the Board of Directors of the Company
 declared a cash dividend of $.07 per share of Common Stock payable
 on January 12, 2007 to holders of record as of the close of
 business on October 30, 2006.

 The Company's working capital of $2,283,600 as of December 31, 2006
 decreased $205,500 from the working capital of $2,489,100 at June
 30, 2006, mostly due to the acquisition of Altamira.  The Company
 has available for its working capital needs, a secured bank line of
 credit of $200,000 with North Fork Bank with interest at prime, all
 of which was available as of December 31, 2006.  The Company has
 never borrowed under this line of credit.  Management believes that
 the Company will be able to meet its cash flow needs during the
 next 12 months from its available financial resources which include
 its cash and investment securities.

 Results of Operations

 Financial Overview

 As previously reported, during the quarter ended December 31, 2006,
 the Company acquired 100% of the outstanding capital stock of
 Altamira, and as a result, the results of Altamira from the date of
 acquisition (November 30, 2006) are reflected in the consolidated
 results of the Company.  In addition, the consolidated results
 reflect certain adjustments related to the recording of the
 acquisition, including adjustments of inventory and fixed assets to
 fair market values, purchased intangible assets, and related
 depreciation and amortization.


 The Three Months Ended December 31, 2006 Compared with the Three
 Months Ended December 31, 2005.

 The Company's net sales for the three months ended December 31,
 2006 increased by $335,200 (36.1%) to $1,263,300 compared with
 $928,100 for the three months ended December 31, 2005 as a result
 of the revenues from the Altamira operation for December 2006,
 partially offset by a $41,100 (4.4%) decrease in the net sales of
 the laboratory equipment operations due to the discontinuance of
 purchases by our previous major laboratory equipment distributor,
 partially offset by increased sales to other distributors and
 higher direct sales.  Altamira's revenues, unlike the laboratory
 equipment revenues, are subject to great volatility from month to
 month because revenues for the catalyst instrument operations are
 mostly comprised of large orders, which typically average over
 $100,000 each.

 The gross profit percentage for the three months ended December 31,
 2006 decreased to 36.5% compared to 50.1% for the three months
 ended December 31, 2005. At the date of Altamira's acquisition, the
 work-in-progress was adjusted upwards to fair value so that the
 adjusted value would allow for the Company's profit allowance upon
 completing the manufacture of orders in process.  All significant
 selling efforts were performed by Altamira prior to acquisition.
 The Company recognizes revenue upon shipment of goods, passage of
 title and customer acceptance.  While revenue has been reported by
 the Company for Altamira's sales post acquisition, a significant
 portion of the gross profit has been attributed to the period
 prior to acquisition.  Accordingly, the gross profit for the period
 was lower than normal by $106,500.  Moreover, gross profit for the
 quarter ended March 31, 2007 is expected to be reduced by $65,000
 for the reasons described above.  In addition, Altamira's normal
 gross profit percentage can vary significantly depending on the
 type of job, while the gross profit percentage for the laboratory
 equipment operations for the three months ended December 31, 2006
 and December 31, 2005 was 50.9% and 50.1%, respectively.

 General and administrative expenses for the three months ended
 December 31, 2006 were $207,600, a decrease of $5,100 (2.4%) from
 $212,700 for the three months ended December 31, 2005, primarily
 due to higher costs incurred by the Company during 2005 in pursuit
 of business opportunities.  The current year's three month period
 includes approximately $17,200 of expenses of Altamira subsequent
 to the acquisition date.




                                  11





 Selling expenses for the three months ended December 31, 2006
 totaled $78,600, an increase of $11,700 (17.5%) from $66,900 for
 the three months ended December 31, 2005 mainly due to selling
 expenses of $24,300 of the acquired operation for December 2006,
 partially offset by lower expenses of our laboratory equipment
 operation.

 Research and development expenses for the three months ended
 December 31, 2006 increased by $10,600 (13.5%) to $89,000 as
 compared to $78,400 for the three months ended December 31, 2005 as
 a result of the expenses incurred in developing our licensed
 disposable sensor products.

 Interest and other income increased $6,500 (59.6%) to $17,400 for
 the three months ended December 31, 2006 compared with $10,900 for
 the three months ended December 31, 2005 mainly due to higher
 interest rates and balances of investment securities for the
 majority of the current year's period.

 As a result of the above, the Company's income before income taxes
 was $103,200 for the three months ended December 31, 2006, a decrease
 of $14,400 (12.2%) as compared to $117,600 for the three months ended
 December 31, 2005.

 Income taxes were $34,100 for the three months ended December 31,
 2006 compared to $27,900 for the comparable period last year,
 mainly because the anticipated rate in the 2005 period was based on
 slightly lower rate for the year.

 As a result of the above, the Company's net income was $69,100 for
 the three months ended December 31, 2006, a decrease of $20,600
 (23.0%) as compared to $89,700 for the three months ended
 December 31, 2005.


 The Six Months Ended December 31, 2006 Compared with the Six Months
 Ended December 31, 2005.

 The Company's net sales for the six months ended December 31, 2006
 increased by $248,100 (13.7%) to $2,066,200 compared with
 $1,818,100 for the six months ended December 31, 2005 as a result
 of the revenues of $376,300 of the acquired catalyst research
 instrument operations for December 2006, partially offset by a
 $128,200 (7.1%) decrease in net sales of our laboratory equipment
 operations, the result of the discontinuance of purchases by our
 previous major customer.  The loss of such sales was partially
 offset by increased sales to other distributors and higher direct
 sales.  The acquired operation's revenues are subject to great
 volatility from month to month because its revenues are mostly
 comprised of a few orders, which typically average over $100,000 each.

 The gross profit percentage for the six months ended December 31,
 2006 decreased to 42.4% compared to 50.7% for the six months ended
 December 31, 2005. At the date of Altamira's acquisition, the
 work-in-progress was adjusted upwards to fair value so that the
 adjusted value would allow for the Company's profit allowance upon
 completing the manufacture of orders in process.  All significant
 selling efforts were performed by Altamira prior to acquisition.
 The Company recognizes revenue upon shipment of goods, passage of
 title and customer acceptance.  While revenue has been reported by
 the Company for Altamira's sales post acquisition, a significant
 portion of the earnings thereon have been attributed to the period
 prior to acquisition.  Accordingly, the gross profit for the period
 was lower than normal by $106,500.  Moreover, gross profit for the
 quarter ended


                                 12






 March 31, 2007 is expected to be reduced by $65,000 for the reasons
 described above.  The normal gross profit percentage for the
 Altamira operation can vary significantly depending on the type
 of job.  The gross profit percentage for the six months ended
 December 31, 2006 for the laboratory equipment operations was
 51.2%, a slight increase from 50.7% for the comparable period
 last year, mostly as a result of lower factory overhead.

 General and administrative expenses for the six months ended
 December 31, 2006 were $372,200, a decrease of $14,500 (3.7%) from
 $386,700 for the six months ended December 31, 2005, primarily due
 to the higher costs incurred by the Company in pursuit of business
 opportunities in the prior year's comparable period.  The current
 year's three month period includes approximately $17,200 of
 expenses of Altamira subsequent to the acquisition date.

 Selling expenses for the six months ended December 31, 2006 totaled
 $148,800, an increase of $18,400 (14.1%) from $130,400 for the six
 months ended December 31, 2005 mainly due to selling expenses of
 $24,300 for December 2006 incurred by the acquired operation,
 partially offset by a reduction of selling expenses of the
 laboratory equipment operations.

 There was no material change in research and development expenses-
 $168,400 for the six months ended December 31, 2006 compared with
 $170,200 for the prior year's six month period.

 Interest and other income increased $13,400 (72.8%) to $31,800 for
 the six months ended December 31, 2006 compared with $18,400 for
 the six months ended December 31, 2005 mainly due to higher
 interest rates and balances of investment securities for most of
 the 2006 period.

 As a result of the above, the Company's income before income taxes
 was $217,800 for the six months ended December 31, 2006, a decrease
 of $34,700 (13.7%) as compared to $252,500 for the six months ended
 December 31, 2005.

 Income taxes were $71,100 for the six months ended December 31,
 2006 compared to $65,900 for the comparable period last year,
 mainly because the anticipated rate in the 2005 period was based on
 a slightly lower rate for fiscal 2006.

 As a result of the above, the Company's net income was $146,700 for
 the six months ended December 31, 2006, a decrease of $39,900 (21.4%)
 as compared to $186,600 for the six months ended December 31, 2005.
