                MISONIX REPORTS FISCAL THIRD QUARTER EPS OF $0.04
                           ON 19% INCREASE IN REVENUES


FARMINGDALE,  N.Y.,  (APRIL  29,  2003)  MISONIX,  INC.  (NASDAQ NM: MSON) today
reported  financial  results for the three and nine months ended March 31, 2003.
Highlights  include:

     -    Revenue  increased  19%  and 10% over the three and nine-month periods
          ended  March  31,  2002,  respectively.
     -    Diluted  earnings per share increased to $0.04 and $0.06, from $(0.03)
          and  $0.00  in  the  comparable  prior-year  periods,  respectively.
     -    Medical device revenues increased 95% and 45% compared with prior-year
          periods,  respectively.
     -    Backlog  of  unfilled  orders  increased  57%  from  June  30,  2002.
     -    Misonix  and  Hearing  Innovations continue to expand marketing of the
          HiSonic  and  HiSonic  Tinnitus  Relief  Device  (TRD).

Revenues  for  the  fiscal  2003  third  quarter  ended March 31, 2003 were $8.7
million, a 19% increase from $7.4 million for the comparable period in the prior
fiscal  year.  The  Company  recorded  net  income of $244,000, or $0.04 diluted
earnings  per  share,  compared  with  a  net loss of ($211,000), or ($0.03) per
share,  for  the  same  period in fiscal 2002.  Revenues included a 95%, or $2.2
million,  increase  in  medical  device sales partially offset by a reduction in
industrial  product sales of 17%, or $846,000.  Diagnostic medical devices sales
increased  59%  to  $2.3  million  from $1.4 million in the year-ago quarter and
therapeutic  medical  devices sales increased 154% to $2.3 million from $895,000
last  year.



The  reduction  in  industrial  products  sales  was  mainly attributed to a 15%
reduction  in  revenue  from  Labcaire's  endoscopic  disinfectant  units, a 45%
reduction  in  scrubber net sales, and a 14% decrease in ductless fume enclosure
sales,  partially  offset  by  a  6%  increase  sales for  industrial ultrasonic
laboratory  products.  The reduction in Labcaire's endoscopic disinfectant units
was  due  to an engineering redesign of some parts, which temporarily slowed the
rate  at  which  such products were shipped.  As of the end of 2003 fiscal third
quarter,  the  engineering  redesign  has  been  completed  and  shipments  have
recommenced.  The  reduction  in  both  wet scrubber and ductless fume enclosure
sales  was  predominately  due  to  poor economic conditions in markets that use
these  products.

Gross  margins  as  a  percentage  of  sales  improved  to  43.9%  from  41.3%,
predominately  due  to  higher  margins  associated  with  increased  sales  of
therapeutic  and  diagnostic  medical  devices.

The  Company continued to invest in Hearing Innovations through secured notes in
the  aggregate  amount  of $49,000 during the fiscal third quarter.  These notes
have  been  fully  reserved for, and the accounting treatment is consistent with
that  of  similar  expenditures  that occurred during fiscal 2002 and 2001.  The
current  ability  of  companies  such  as  Hearing Innovations to access capital
markets or incur third party debt is very limited and is likely to remain so for
the  foreseeable future.  In light of this fact, the Company continues to review
strategic  options  available  to  it  and  Hearing  Innovations  due to Hearing
Innovations'  continuing  need  for  financial  support.

Revenues  for  the  nine months ended March 31, 2003 were $23.9 million, a 10.3%
increase from $21.7 million reported for the same period in the prior year.  The
Company  recorded  net  income  of $409,000, or $0.06 per diluted share, for the
nine  months  ended  March 31, 2003, compared with net income of $7,000 or $0.00
per  share, for the same period in the prior fiscal year.  Year-to-date revenues
increased  in medical device products by 45%, or $3.6 million, to $11.8 million,
and  revenues decreased in industrial products by 10%, or $1.4 million, to $12.2
million.  The  Company's  nine-month  investment  in Hearing Innovations through
secured  notes  totaled $246,000.  These notes have been fully reserved for, and
the  accounting  treatment  is consistent with that of similar expenditures that
occurred  during  fiscal  2002  and  2001.

The  backlog  of  unfilled  orders  at  March  31,  2003 was $8.0 million, a 57%
increase,  compared  with  $5.1  million  as  of June 30, 2002.  The increase in
backlog  was primarily due to the accumulation of orders for Labcaire's Guardian
product.  This partially occurred as a result of a reduction in shipments taking
place  while  the engineering redesign was completed, and also from the increase
in  therapeutic  medical  device  orders.  The  Company  temporarily  increased
inventories  to support the replacement probe and refurbished systems businesses
at  Sonora  and  the  backlog  of  orders  for the Guardian product at Labcaire.

Michael  A.  McManus, Jr., President and CEO of Misonix, stated, "We are pleased
with the growth in revenues and earnings for the three and nine months of fiscal
2003.  We  are  encouraged  by  the increase in sales of our therapeutic medical
devices  and  at  Sonora  with  respect  to  its  First  Call  2000  product.



The  Hearing  Innovations  TRD has been launched in the Northeast U.S. While the
results  to  date  have  been slower than expected, we continue to be optimistic
about  its  potential.  We  have  been  making  ongoing  modifications  to these
products  as  we  obtain customer feedback.  The headset is now more comfortable
and  the  importance of proper placement is better overall. We are continuing to
educate  audiologists on the fitting and follow up necessary for patient success
with  the  HiSonic  TRD.  The  increased  profile of the product has enabled our
Company  to  continue discussions with potential distributors.  Clinical success
also  has  resulted  in contacts coming to us from other potential distributors.
We began an analysis of the HiSonic's potential benefits for the profoundly deaf
at  clinics  associated  with  New  York  Hearing  Centers."

"Focus Surgery continues to successfully treat patients in Asia and Europe," Mr.
McManus  added.  "The  clinical trials for treatment of men with prostate cancer
continue  to  be  successful.  The prototype product for the treatment of kidney
cancer  has  completed its animal testing and will now begin a review of results
and  design  suggestions  from  prominent  urologists."

Mr.  McManus  continued,  "One  of  the  great  satisfactions in these financial
results comes from the fact that we are meeting the high expectations we set for
this year.  We continue to remain comfortable with annual revenues increasing by
approximately 10% over the prior fiscal year results and with annual earnings of
approximately  $0.15  per  diluted  share.  "

Misonix  develops,  manufactures,  and/or  markets  medical,  scientific  and
industrial  ultrasonic  and  air pollution systems and maintains minority equity
positions  in  both  Focus  Surgery  and  Hearing  Innovations  as its exclusive
manufacturer  of  the  Sonoblate  500,  HiSonic  and  HiSonic  TRD  devices.
