                  pursuant to the Securities and Exchange
                  Commission's rules and regulations for reporting

     The accompanying condensed consolidated financial statements
     include the accounts of the Company and its subsidiaries:

     "Agreement") whereby the Company paid or issued to the then
     holders of the capital stock of Altamira $400,000 in cash and
     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 the years ending June 30, 2008, June 30, 2009 and
     June 30, 2010 and the fifth period is 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,
     including 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 valuations performed in conjunction
     with the acquisition.  In addition, other fair market value
     adjustments were made in conjunction with the acquisition,
     primarily 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.  If
     the election is not made under the Internal Revenue Code, 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
     their estimated fair market values at the date of the
     acquisition.  The preliminary allocation of the net purchase
     price was 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 other intangible assets, $237,000 was
     allocated to customer relationships with a weighted-average
     estimated useful life of 10 years, $300,000 was allocated to
     technology including trade names and trade marks with a useful
     life of 5 years, and $102,000 was allocated to a non-compete
     agreement with a useful life of 5 years.  The amount allocated
     to the customer relationships is 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 two segments: the manufacture 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 manufacture 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 following the acquisition.

 Segment information is reported as follows:

     Approximately 69% and 73% of net sales of the laboratory
     equipment operations for the three month periods ended March
     31, 2007 and 2006, respectively, and approximately 70% and 76%
     of net sales of the laboratory equipment operations for the
     nine month periods ended March 31, 2007 and 2006, respectively
     were derived from the Company's main product, the Vortex-Genie
     2(R) mixer, excluding accessories.

     Of the laboratory equipment operations' net sales, two
     customers accounted for approximately 33% and 37% for the three
     and nine month periods ended March 31, 2007, respectively, and
     three customers accounted for 49% for each of the three and
     nine month periods ended March 31, 2006.  Sales of the catalyst
     research instruments operations are to a limited number of
     customers who are purchasing instruments customized pursuant to
     the customer's specifications.  Generally, the average order is
     more than $100,000.  Accordingly, sales to five customers
     accounted in the aggregate for approximately 98% and three of
     the five accounted for 95% of the net sales of the operations
     for the nine and three month periods ended March 31, 2007,
     respectively.

     The Company's consolidated export sales (principally Europe and
     Asia) were approximately $607,600 and $425,000 for the three
     month periods ended March 31, 2007 and 2006, respectively, and
     $1,543,400 and $1,208,000 for the nine month periods ended
     March 31, 2007 and 2006, 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 nine month periods ended
     March 31, 2007 and 2006.

 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:

                         For the Three Months   For the Nine Months
                         Ended March 31, 2006   Ended March 31, 2006

       Diluted - pro forma            $ .10               $ .27


     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 incurred stock-based compensation costs
     of $4,000 for the three and nine months ended March 31, 2007.


                                  8





 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,
     including customer relationships, non-compete agreements and
     technology which encompasses trade names, trade marks and
     licenses.  The valuation resulted in an initial negative
     goodwill of approximately $91,500 on the date of acquisition.
     However, the Stock Purchase Agreement provides for contingent
     future payments based on net catalyst research instrument
     operations 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 March 31, 2007 the
     negative goodwill, which has been classified as a deferred
     credit, was reduced to $50,000 mostly 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
     March 31, 2007, 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 event we may be required to record impairment
     charges for these assets.

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

     The components of intangible assets as of March 31, 2007 were
     as follows:
                                 Gross                    Net

              SCIENTIFIC INDUSTRIES, INC. AND SUBSIDIARIES

     Total amortization expense related to intangible assets was
     $39,400 and $59,600 for the three and nine months ended March
     31, 2007, respectively, and $1,700 and $4,800 for the three and
     nine months ended March 31, 2006, respectively.  As of March
     31, 2007, estimated future amortization expense related to
     intangible assets is $39,000 for the remainder of fiscal 2007,
     $147,400 for fiscal 2008, $132,600 for fiscal 2009, $122,900

 ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATIONS

 Certain statements contained in this report are not based on
 historical facts, but are forward-looking statements that are based
 upon various assumptions about future conditions.  Actual events in
 the future could differ materially from those described in the
 forward-looking information.  Numerous unknown factors and future
 events could cause such differences, including but not limited to,
 product demand, market acceptance, impact of competition, the
 ability to reach final agreements, the ability to produce and
 finance catalyst research instruments to customers' satisfaction,
 adverse economic conditions, and other factors affecting the
 Company's business that are beyond the Company's control.
 Consequently, no forward-looking statement can be guaranteed.

 We undertake no obligation to publicly update forward-looking
 statements, whether as a result of new information, future events or
 otherwise.

 Liquidity and Capital Resources

 Cash and cash equivalents increased by $176,700 to $404,400 as of
 March 31, 2007 from $227,700 as of June 30, 2006.

 Net cash provided by operating activities was $225,300 for the nine
 month period of the current fiscal year as compared to $214,400 in
 the comparative period for 2006, mainly the result of higher
 balances of accounts receivable, accounts payable and customer
 advances partially offset by higher inventories and accrued
 expenses. Cash provided by investing activities was $13,400 for the
 current nine month fiscal period as compared to cash used of
 $172,500 for the nine months ended March 31, 2006, primarily the
 result of net cash of $346,500 used in connection with the
 acquisition of Altamira, and larger redemptions of investment
 securities due to cash needed for the acquisition.

 Net cash used in financing activities reflected a cash dividend of
 $.07 per share of Common Stock which was paid on January 12, 2007
 to holders of record as of the close of business on October 30, 2006.



                                   10




 The Company's working capital of $2,327,600 as of March 31, 2007
 decreased $161,500 from the working capital of $2,489,100 at June
 30, 2006, mostly due to the acquisition.  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 March 31, 2007.  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, the Company acquired on November 30, 2006,
 100% of the outstanding capital stock of Altamira, and therefore
 the results of Altamira from the date of acquisition 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 March 31, 2007 Compared with the Three
 Months Ended March 31, 2006.

 The Company's net sales for the three months ended March 31, 2007
 increased by $421,600 (45.9%) to $1,341,000 as compared with
 $919,400 for the three months ended March 31, 2006 as a result of
 the addition of the sales of the catalyst research instrument
 operations.  Net sales of the laboratory equipment operations
 increased slightly by $9,700 (1.1%) despite the discontinuance of
 purchases by a major customer and laboratory equipment distributor.
  The catalyst research instruments' revenues, unlike those of the
 laboratory equipment operations, are subject to great volatility
 from period to period because revenues for the catalyst research
 instruments are mostly comprised of a small number of large orders,
 which typically average more than $100,000 each.

 The gross profit percentage for the three months ended March 31,
 2007 decreased to 38.4% as compared to 48.7% for the three months
 ended March 31, 2006. 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 - the effect of which reduced the gross profit for
 the period by $65,000. In addition, the gross profit for the
 catalyst research instruments  operations may vary significantly
 depending on the type of order.  The gross profit percentage for
 the laboratory equipment operations for the three months ended
 March 31, 2007 and March 31, 2006 was 51.2% and 48.7%,
 respectively, the increase resulting from lower price discounts.

 General and administrative expenses for the three months ended
 March 31, 2007 were $279,500, an increase of $102,800 (58.2%) as
 compared with $176,700 for the three months ended March 31, 2006,
 primarily due to the addition of the general and administrative
 expenses incurred during the period  by the newly-acquired catalyst
 research instruments operations and acquisition-related
 administrative integration costs.

 Selling expenses for the three months ended March 31, 2007 totaled
 $114,100, an increase of $59,500 (109.0%) from $54,600 for the
 three months ended March 31, 2006, mainly due to the addition of
 the selling expenses of the acquired catalyst research instruments
 operations.

 Research and development expenses for the three months ended March
 31, 2007 decreased by $6,900 (9.5%) to $66,000 as compared to
 $72,900 for the three months ended March 31, 2006 due to fewer
 outside engineering services for the laboratory equipment
 operations; no research and development expenses were incurred in
 the catalyst research instruments operations during the quarter.

 The Company's income before income taxes was $64,800 for the three
 months ended March 31, 2007, a decrease of $90,900 (58.4%) as
 compared to $155,700 for the three months ended March 31, 2006.

 Income taxes were $23,000 for the three months ended March 31, 2007
 compared to $53,500 for the comparable period last year, mainly due
 to lower income.

 The Company's net income was $41,800 for the three months ended
 March 31, 2007, a decrease of $60,400 (59.1%) as compared to
 $102,200 for the three months ended March 31, 2006.

 The Nine Months Ended March 31, 2007 Compared with the Nine Months
 Ended March 31, 2006.

 The Company's net sales for the nine months ended March 31, 2007
 increased by $669,700 (24.5%) to $3,407,200 as compared with
 $2,737,500 for the nine months ended March 31, 2006 as a result of
 $788,200 of revenues of the acquired catalyst research instruments
 operations, partially offset by a $118,500 (4.3%) decrease in net
 sales of our laboratory equipment operations.  The reduction in
 laboratory equipment operations sales was due to the discontinuance
 of purchases by a major customer and laboratory equipment
 distributor, partially offset by increased sales to other
 distributors and increased direct sales.  The catalyst research
 instruments operations' revenues are subject to great volatility
 from period to period because they are mostly comprised of a few
 large orders, which typically average more than $100,000 each.

 The gross profit percentage for the nine months ended March 31,
 2007 decreased to 40.8% as compared to 50.0% for the nine months
 ended March 31, 2006. At the date of the Altamira 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 revenues have been reported
 by the Company for the catalyst research instruments operations
 post-acquisition, a significant portion of the gross profit has
 been attributed to the period prior to acquisition, the effect of
 which was to reduce the gross profit for the period by $171,000.

 operations was 51.2%, a slight increase from 50.0% for the
 comparable period last year, mostly as a result of lower price
 discounts.

 General and administrative expenses for the nine months ended March
 31, 2007 were $651,700, an increase of $88,300 (15.7%) from
 $563,400 for the nine months ended March 31, 2006, primarily due to
 the addition of such expenses by the catalyst research instruments
 operations and acquisition-related administrative integration
 costs.

 Selling expenses for the nine months ended March 31, 2007 totaled
 $262,900, an increase of $77,900 (42.1%) as compared with $185,000
 for the nine months ended March 31, 2006 mainly due to the addition
 of the selling expenses incurred by the catalyst research
 instruments operations, partially offset by a reduction of selling
 expenses of the laboratory equipment operations due to lower
 salaries.

 There was no material change in research and development expenses-
 $234,400 for the nine months ended March 31, 2007 compared with
 $243,100 for the prior year's nine month period.  No research and
 development expenses for the catalyst research instruments
 operations were incurred during the post-acquisition period through
 March 31, 2007.

 Interest and other income increased $10,800 (34.8%) to $41,800 for
 the nine months ended March 31, 2007 as compared with $31,000 for
 the nine months ended March 31, 2006 mainly due to higher interest
 rates and balances of investment securities for most of the 2007
 period.

 As a result of the above, the Company's income before income taxes
 was $282,600 for the nine months ended March 31, 2007, a decrease
 of  $125,600 (30.8%) as compared to $408,200 for the nine months
 ended March 31, 2006.

 Income taxes were $94,100 (33.3%) for the nine months ended
 March 31, 2007 compared to $119,400 (29.3%) for the comparable
 period last year, mainly due to lower income in the current
 period.  The current period's tax rate was higher mainly due to
 smaller amounts of credits available.

 The Company's net income was $188,500 for the nine months ended
 March 31, 2007, a decrease of $100,300 (34.7%) from $288,800 for
 the nine months ended March 31, 2006.
