CRYOPAK CORP. TESTING LABORATORIES TEST RESULTS

                             DATED AUGUST 12, 1996.

CLIENT - XXX

PURPOSE OF TEST - The test was conducted to compare equal weights of Cryomat and
Gel Paks in a Polyfoam 38-I Styrofoam box with outer corrugated container.  I.D.
of  box  was  10  3/4  in.  X  71/2in.  X  101/2in.  Test  was  conducted  using
pharmaceutical  standard  protocol of varying  ambient  temperature  during test
period.

EQUIPMENT  -  Individual  boxes  were  placed in a heat  controlled  environment
utilizing  a Fuji  Electric  PYZ series  ramp-to  setpoint  controller  with PID
control  maximizing  process  stability.  Electric  element  heating  coils were
controlled  by this  system  yielding  an average  temperature  ranges with +- 1
degree C.  accuracy.  (AMBIENT) A Lakewood UL-16 Ultra Logger was used to record
product  temperature,  and ambient  temperature via eight temperature  recording
probes.  The probes were placed within the product  sample as illustrated in Fig
___.

AMIBENT AIR TEMPERATURE - The temperature protocol maintained during the testing
period was as follows:

30 deg. C. for 18 hours.
38 deg. C. for next 6 hours.
47 deg. C. for next 2 hours.
30 deg. C. for next 16 hours.
37 deg. C. for next 3 hours.*

* The test was discontinued at this point since both test containers had reached
16 deg. C at this time and were considered well outside of the acceptable  range
for temperature sensitive pharmaceuticals.

PACKAGING TECHNIQUE

Container #1

3.3 kg. of Cryomat  was  placed in the  shipping  container  in such a way as to
totally surround the inner box of product mass. Cryomat was placed (double layer
down both  sides and both  ends) A triple  layer of  Cryomat  was  placed on the
bottom and the top of test mass inner  container.  Temperature  probes ( Cryomat
#1,  Cryomat  #2, and Cryomat #3) were  placed  directly  into the product  mass
within the inner box as illustrated in Fig.----

Container #2

3.3 kg. of Gel Paks were placed in  container  as used in actual  pharmaceutical
shipping  situation (2) 1/2 kg. and (1) 1 kg. Gel paks were placed down one side
of inner container.  (3) 1/2 kg. Gel paks were placed on top of inner container.
Inner  container  was butted up to outer  container  on three  sides and bottom.
(i.e. no direct contact with Gel Paks) Temperature  probes (Gel Pak # 1, Gel Pak
#2, and Gel Pak #3) were placed  directly into the product as shown in Fig. ---,
The Probe Gel Pak #4 was placed just inside of the inner  container  as far from
the Gel Paks as possible.

OBSERVATIONS- The Graphic  representation  of the test clearly  demonstrates the
superiority  of  Cryomat.  throughout  the  duration  of  the  test.  The  probe
recordings were  consistent for all three probes and a temperature  below 5 deg.
C. was  maintained  for 35 hours.  The critical upper range of 8 deg. C. was not
reached by any probe for a forty hour period.

A wide  separation  indicating a significant  temperature  variance was observed
with the Gel Pak  temperature  probes.  The Gel Pak #3 probe  exceeded the upper
critical limit within six hours. The Gel Pak k probe exceeded the upper critical
limit  within  19 hours  and the  single  Gel Pak #1 probe  exceeded  the  upper
critical limit in 36 hours.  This clearly  demonstrates that a large temperature
gradient  exists  through the product mass when using the Gel Paks. For the most
part the product mass temperature is outside of the critical  temperature  range
with this packaging configuration.

The Gel Pak #4 probe indicates the actual  temperature of the product at a point
most distant from the Gel Pak location.  THE PRODUCT  TEMPERATURE  AT THIS POINT
WAS NEVER WITHIN THE REQUIRED CRITICAL TEMPERATURE RANGE.

Further  observations  of the  graphs  indicates  the  protective  nature of the
Cryomat  packaging with a rapid increase in outside  (ambient) air  temperature.
When the ambient air  temperature was increased to 38 deg. C and then to 47 deg.
C. The temperature within the Gel Pak configuration  increased immediately while
the "wrap around"  configuration  with the Cryomat protected the product against
these increases.  This is indicated by the "humps"  appearing on all the Gel Pak
probe curves during temperature  increase.  On the other hand, the Cryomat probe
curves showed very little fluctuation during the temperature increase.

CONCLUSIONS-  It can be  concluded  that  Cryomat  offers  superior  refrigerant
properties  when compared to the Gel Pak, The "wrap  around"  ability of Cryomat
assures a uniform  transfer of heat from the product over an extended  period of
time.  The  characteristic  uniformity of the Cryomat curves in Chart I indicate
that  amount of  Cryomat  used could be  reduced  to  achieve  required  results
depending on the time required under actual shipping conditions.

The  separation  of the Gel  Pak  curves  in  Chart !  indicate  a  considerable
temperature  differential  across the product mass. This differential is evident
throughout the entire test period.

The "protective"  nature of Cryomat under conditions of temperature spiking will
be important  to the shipper of  perishable  products  since the  likelihood  of
product heating in unpredictable temperature extremes is minimized.
