                  accepted in the United States for complete
                  financial statements are not included herein. The
                  Company believes all adjustments necessary for a
                  fair presentation of these interim statements
                  have been included and are of a normal and
                  recurring nature.  These interim statements
                  should be read in conjunction with the Company's
                  financial statements and notes thereto, included
                  in its Annual Report on Form 10-KSB for the
                  fiscal year ended June 30, 2005.  The results for
                  the three and nine months ended March 31, 2006,
                  are not necessarily an indication of the results
                  of the full fiscal year.

 1.  Significant accounting policies:

 Principles of consolidation:

     The accompanying condensed consolidated financial statements
 include the accounts of the Company and Scientific Packaging
 Industries, Inc., a New York corporation which is an inactive
 wholly owned subsidiary of the Company.  All intercompany items
 and transactions have been eliminated in consolidation.

 2.  Line of Business and Concentrations:

     The Company is engaged in the manufacture and marketing of
 equipment for research in university, hospital and industrial
 laboratories.  The Company believes that it has only one
 reportable segment.  Approximately 73% and 76% of net sales for
 the three and nine month periods ended March 31, 2006,
 respectively, were derived from the Company's main product, the
 Vortex-Genie  2, compared to 78% and 74% in the comparable prior
 year periods.

     The Company's export sales (principally Europe and Asia) were
 approximately $424,600 and $448,400 for the three month periods
 ended March 31, 2006 and 2005, respectively, and $1,207,700 and
 $1,196,800 for the nine month periods ended March 31, 2006 and
 2005, respectively.

     Three of the Company's customers accounted in the aggregate
 for 49% of net sales for both of the three month periods ended
 March 31, 2006 and 2005, and 49% and 51% of net sales for the nine
 month periods ended March 31, 2006 and 2005, respectively (see
 Financial Overview).

 3.  Inventories:

     Inventories for interim financial statement purposes are based
 on perpetual inventory records.  Components of inventory are as
 follows at March 31, 2006:
                                          March 31, 2006

                                          ==============
 4.  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 includes the dilutive effect of
 stock options and a warrant, which was exercised at the end of
 September 2005.


     Earnings per common share were computed as follows:

                             For the Three Month   For the Nine Month

 All options outstanding as of March 31, 2006 and 2005 were
 included in the foregoing computations.  A warrant for the
 exercise of 17,391 shares was included in the calculation for the
 periods prior to its exercise in September 2005.

 5.  Comprehensive Income:

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

 6.   Stock-Based Compensation Plans:

     The Company maintains a Stock Option Plan which it accounts
 for under the recognition and measurement principles of APB
 Opinion No. 25, "Accounting for Stock Issued to Employees," and
 related Interpretations.  No stock-based compensation costs are
 reflected in net income, as all options granted under those plans
 had an exercise price equal to the 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, "Accounting for Stock-Based Compensation," to
 stock-based employee compensation:

       Diluted - pro forma     $ .10     $ .09      $ .27       $ .20

     On December 16, 2004, the Financial Accounting Standards Board
 issued Statement No. 123 (revised 2004) that will require
 compensation costs related to share-based payment transactions to
 be recognized in the financial statements.  With limited
 exceptions, the amount of compensation cost will be 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 cost will be
 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.
 SFAS 123(R) is effective for the Company's fiscal year beginning
 July 1, 2006.  The Company is currently assessing the impact which
 SFAS 123(R) will have.

 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, success of
 marketing strategy, impact of competition, relationships with
 principal customers, the ability to reach final agreements,
 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

 Net cash provided by operating activities increased to $214,400
 for the nine months ended March 31, 2006 as compared to $173,900
 for the same nine month period of the prior fiscal year; the
 increase of $40,500 was primarily due to higher income.  Cash used
 in investing activities was $172,500 for the current nine month
 period as compared to $232,000 for the nine months ended March 31,
 2005, a decrease of $59,500, mainly as a result of higher
 redemptions of investment securities during the current nine month
 period.  Cash used in financing activities for the nine months
 ended March 31, 2006 was $77,600, compared to $62,400 for the
 prior year's nine month period, an increase of $15,200 due to the
 higher cash dividend paid in the 2006 period.  As a result of the
 foregoing, cash and cash equivalents decreased by $35,700 to
 $148,200 as of March 31, 2006 from a balance of $183,900 as of
 June 30, 2005.

 The Company's working capital as of March 31, 2006 increased
 $252,500 to $2,501,300 from $2,248,800 at June 30, 2005, mainly
 due to income from operations, partially offset by the cash
 dividend.  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, 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 for its operations during the next 12 months
 from its available  financial resources which include its cash
 and investment securities.

 Results of Operations

 Financial Overview

 Due mainly to higher sales, lower operating expenses, and higher
 interest income, the Company achieved income before income taxes
 of $408,200 for the nine months ended March 31, 2006 compared to
 $313,900 for the nine months ended March 31, 2005. Income before
 income taxes for the three month comparison period ended March 31,
 2006, however, was approximately the same at $155,700 compared to
 $158,500.

 The Company was recently informed by its principal customer and
 distributor for more than 30 years of a change in its selling and
 marketing methods.  While the distributor will continue to offer
 the Vortex-Genie(R) 2 Mixer, it will discontinue the product's
 current catalogue number which has been associated with the
 product for many years and assign it a different catalogue number.
  It will also exclude the product from future printed catalogues;
 however, the product will still appear on its website.  The
 Company believes that the distributor intends to market and
 promote a competitive private label product.  As a result of the
 change, the distributor will no longer purchase products from the
 Company for inventory; all sales to the distributor's customers
 will be filled by the Company through direct shipment.  Sales to
 the distributor of the Company's products, predominantly the
 Vortex-Genie(R) 2 Mixer and related accessories, accounted for
 approximately 23% and 24% of the Company's revenues for the three
 and nine month periods ended March 31, 2006 respectively, and 25%
 and 23% for the comparable three and nine month periods of the
 prior year.  The Company is undertaking measures to mitigate the
 expected impact on sales and income, including an increase in its
 direct selling efforts and working with other distributors to
 increase their distribution of the Company's products.

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

 Net sales for the three months ended March 31, 2006 decreased by
 $76,900 (7.7%) to $919,400 as compared with $996,300 for the three
 months ended March 31, 2005, primarily due to the unusually high
 level of orders filled in the quarter ended March 31, 2005 due to
 a temporary supplier problem in the previous quarter.  Due
 primarily to increasing raw material costs, the gross profit
 margin was reduced to 48.7% ($447,300) for the three months ended
 March 31, 2006, from 52.0% ($517,600) for the three months ended
 March 31, 2005.

 The amounts of general and administrative expenses for the three
 month comparative periods were substantially the same, $176,700
 for the March 31, 2006 quarter and $176,200 for the March 31, 2005
 quarter.



                                 8



           SCIENTIFIC INDUSTRIES, INC. AND SUBSIDIARY


 Selling expenses for the three months ended March 31, 2006
 decreased by $20,900 (27.7%) to $54,600 as compared to $75,500 for
 the three months ended March 31, 2005, mainly due to lower salary
 expense and costs related to trade shows.  The reduction in salary
 expense resulted from the resignation in February 2006 of the
 Marketing Director, and subsequent hiring of a replacement at a
 lower salary.

 Research and development expenses for the three months ended March
 31, 2006 were $36,100 (33.1%) lower at $72,900 compared to
 $109,000 for the prior year's three month period, during which
 substantial expenses were incurred in the development of the
 Multi-MicroPlate Genie  Mixer.

 Interest and other income increased to $12,600 for the three
 months ended March 31, 2006 from $1,600 for the prior year's three
 month period due to higher interest rates and higher balances of
 investment securities.

 Income tax expense for the three months ended March 31, 2006 was
 $53,500 as compared with $63,800 for the prior year's quarter.

 As a result of the foregoing, net income was $7,500 greater,
 $102,200 for the three months ended March 31, 2006 compared to
 $94,700 for the year earlier quarter.


 The Nine Months Ended March 31, 2006 Compared with the Nine Months
 Ended March 31, 2005.

 Net sales increased $44,300 (1.6%) to $2,737,500 for the nine
 months ended March 31, 2006 compared to $2,693,200 for the nine
 months ended March 31, 2005, primarily due to a further increase
 in sales of new products.

 The gross profit margin of 50.0% for the nine months ended March
 31, 2006, was slightly higher than the gross profit margin of
 49.1% for the nine months ended March 31, 2005 due mainly to lower
 overhead costs.

 General and administrative expenses for the nine months ended
 March 31, 2006 were $563,400, an increase of $41,800 (8.0%), as
 compared with $521,600 for the nine months ended March 31, 2005
 mainly as a result of an increase in costs for investigating
 business opportunities.

 Selling expenses for the nine months ended March 31, 2006 were
 $185,000 or $39,700 (17.7%) less than $224,700 for the nine months
 ended March 31, 2005, due mostly to lower trade show costs and
 salary expense; the latter due to the change in marketing
 personnel during the quarter.



                                   9





 Research and development expenses were $243,100 for the nine
 months ended March 31, 2006, $36,300 (13.0%) less than $279,400
 for the comparable prior year period during which substantial
 development costs for the new Multi-MicroPlate Genie(TM) were
 incurred.

 Interest and other income increased $14,900 to $31,000 for the
 nine months ended March 31, 2006 compared to $16,100 for the nine
 months ended March 31, 2005 due to higher interest rates and
 balances of investment securities.

 Income before income taxes increased $94,300 (30.0%) to $408,200
 for the nine months ended March 31, 2006 compared to $313,900 for
 the nine months ended March 31, 2005, and as a result, income tax
 expense was $119,400 for the nine months ended March 31, 2006,
 compared to $99,800 for the prior year comparable nine month period.

 As a result of the foregoing, net income increased by $74,700
 (34.9%) to $288,800 for the nine months ended March 31, 2006 from
 $214,100 for the nine months ended March 31, 2005.

 ITEM 3.  CONTROLS AND PROCEDURES

 As of the end of the period covered by this report, based on an
 evaluation of the Company's disclosure controls and procedures (as
 defined in Rules 13a-15(e) and 15d-15(e) under the Securities
 Exchange Act of 1934), the Chief Executive and Chief Financial
 Officer of the Company concluded that the Company's disclosure
 controls and procedures are effective to ensure that information
 required to be disclosed by the Company in its Exchange Act
 reports is recorded, processed, summarized and reported within the
 applicable time periods specified by the SEC's rules and forms.

 There was no change in the Company's internal controls over
 financial reporting that occurred during the most recent fiscal
 quarter that materially affected or is reasonably likely to
 materially affect the Company's internal controls over financial
 reporting.
