  MISONIX REPORTS RECORD REVENUES AND INCREASED EARNINGS FOR FISCAL YEAR ENDED
                                  JUNE 30, 2003



FARMINGDALE,  NY,  AUGUST  26, 2003 - MISONIX, INC. (NASDAQ:MSON) today reported
fiscal  results for the three and twelve months ended June 30, 2003.  Highlights
for the fiscal year ended June 30, 2003 are as follows:

- -    Revenues  for the fiscal year ended June 30, 2003 increased 18% to a record
     $34.9  million  from  $29.6  million  in  fiscal  2002.
- -    Net  income  for  the  fiscal  year  ended  June 30, 2003 increased 448% to
     $968,000,  or  $0.15  per  fully  diluted share from $177,000, or $0.03 per
     fully  diluted  share.
- -    Operating  income  for  the  fiscal year ended June 30, 2003 increased 219%
     from  $496,000  in  the  prior  fiscal  year  to  $1.6  million.
- -    Gross  Margin  rose  to 41.6% as a percentage of sales in fiscal 2003, from
     39.4%  in  the  prior  fiscal  year.
- -    Focus  Surgery's SB-500 has successfully treated over 200 patients in Japan
     for  prostate  cancer  and  106  in  Europe.
- -    Misonix and Focus Surgery continue to ship the SB-500 product to Europe and
     Asia  for  the  treatment  of  enlarged  prostate  and  prostate  cancer.
- -    Misonix  and Hearing Innovations continue to explore opportunities to treat
     tinnitus  and  profound  deafness.


Revenues  for  the  fiscal  2003  fourth  quarter ended June 30, 2003 were $10.9
million,  a  38%  increase  over  $7.9  million for the same period in the prior
fiscal  year.  The  Company recorded net income for the fourth quarter of fiscal
year  ended  June  30,  2003



of  $559,000,  or  $0.08  per  fully  diluted  share,  compared to net income of
$170,000,  or $0.03 per fully diluted share, for the same period in fiscal 2002.
Medical  device  revenues  increased  61% to $5.7 million and industrial product
revenues  increased 20% to $5.2 million. The increase in medical device revenues
was  attributed  to a 41% increase in diagnostic medical device revenues to $2.8
million  and  an  87%  increase  in  therapeutic medical device revenues to $2.9
million.  The industrial product revenue increase was mainly attributed to a 25%
increase  from  Labcaire's  endoscopic  cleaning  and  disinfectant units, a 32%
increase  in  industrial  ultrasonic laboratory equipment, and a 29% increase in
wet  scrubber  sales.

Gross  profit was favorably impacted during the fourth quarter of fiscal 2003 by
a combination of volume efficiencies derived from increased sales as compared to
the  same  period  in  the prior year and cost reductions implemented during the
2003  fiscal  year. The Company continued to invest during the fourth quarter of
fiscal  2003  in  Hearing  Innovations, Inc. in the form of secured notes in the
aggregate  amount  of  $66,000.  The notes have been fully reserved for and have
been  accounted  for  consistently  with  the  prior  fiscal  period.

Revenues  for  the  twelve months ended June 30, 2003 were $34.9 million, an 18%
increase  when compared to $29.6 million for the same period in the prior fiscal
year.  The  Company  recorded net income of $968,000, or $0.15 per fully diluted
share,  compared  to  $177,000, or $.03 diluted earnings per share, for the same
period  in  fiscal 2002. Medical device revenues increased 50% to $17.5 million,
partially offset by a 3% reduction in industrial product sales to $17.4 million.
Gross  profit  was  favorably  impacted  during the twelve months ended June 30,
2003,  as  the Company was able to take advantage of volume efficiencies and the
results  of  cost  reduction  efforts,  which



have  been implemented during the entire fiscal year 2003. The Company continued
to  invest  in  Hearing Innovations for the twelve months ended June 30, 2003 in
the  form  of  secured notes in the aggregate amount of $312,000. The notes have
been  fully reserved for and have been accounted for consistently with the prior
fiscal  period.

At June 30, 2003, the backlog of unfilled orders was $5.6 million, compared with
$5.1 million for the same period in fiscal 2002. Medical device products backlog
was  $3.0  million,  a  7.4%  increase  over the prior year predominately due to
increased  neuroaspirator  orders and industrial product backlog increased 13.4%
to  $2.6  million  over the prior year predominately due to increased orders for
the  Labcaire  Guardian  product.

Michael A. McManus, Jr., President and Chief Executive Office commented, "We are
pleased  by  the  growth  in  our  medical  businesses and the overall growth in
revenues  and  income.  As  you  know,  we  realized record revenues. We believe
Misonix  has turned the corner to a continued growth in revenues and increase in
earnings. Shareholders who have been with us for a number of years will remember
that  we  have  worked  through  a  number of adverse events: the loss of a $5.0
million  product  line  (Lysonix);  the  substantial  drop  in revenues from our
laproscopic  product  in  part  as  a  result  of  corporate reorganization; the
Appellate  Court decision against us in the Mentor matter; and the write down of
our  equity  investments. There are no excuses for these issues or our resulting
performance.  However,  we believe that it is important to note that in the face
of  these  adverse  events,  we were still able to expand our offerings from one
medical  product  to  nine  medical  products  and are successfully growing this
business,  as  you should expect. This expanded product line, and the sales they
are generating, leaves us comfortable with our expectations for continued growth
in  both  revenues  and  income."



Mr.  McManus  continued,  "We are disappointed with the progress we have made to
date in Hearing Innovations and Focus Surgery. The regulatory issues and time to
market  are  more than we anticipated. We continue to see Focus Surgery sell the
SB-500  outside  the U.S. The results on men with prostate cancer continue to be
impressive.  The  number  of men treated successfully in Japan exceeds more than
180 patients. We have completed the first half of Phase I clinical trials in the
U.S. on men who had not previously been treated for cancer. We have treated four
patients  who are recurrent cancer patients. At the same time, Misonix has begun
to  develop products for kidney and liver using high intensity ultrasound (HIFU)
under  our  license agreements with Focus Surgery. Hearing Innovations continues
to  develop  patient studies on both the HiSonic and the TRD for tinnitus. Sales
have been slow in our test market and we are working on resolving any issues. We
will  be  discussing our results on both products with strategic partners. These
meetings  are a continuation of earlier meetings with these potential partners."

"We  continue  to  believe  that  both  of these investments will deliver future
incremental  income.  Both will require more money and time. We have renewed our
efforts  to  assist  Hearing Innovations and Focus Surgery in raising more money
from  strategic  partners  and  investors."

Mr.  McManus  continued,  "We  are  pleased  with  the performance of Sonora and
Fibra-Sonics,  both  fairly  recent acquisitions. Sonora revenues have more than
tripled and Fibra Sonics revenues have more than doubled since we acquired them.
Our  continued investment in people and research has also resulted in a two-fold
increase  in  Labcaire revenues. However, despite a pickup in Labcaire revenues,
the  other products in our



industrial  business  segment  have been affected by the weakness in the overall
economy  and the resulting slow down in purchasing. We continue to believe these
businesses  will  improve  in  fiscal  2004."

"We  will  continue  to  grow  your  company  through both internal and external
development.  Our  goal for fiscal 2004 is to increase revenue by 7% to 10% over
fiscal  2003 results and annual earning increase to approximately $0.20 to $0.22
per  diluted share. We will also look at strategic transactions and partnerships
as  ways  to  enhance  shareholder  value,"  Mr.  McManus  concluded.
