Dear Jim,

For the best morphological preservation, you need to have the best
fixation.  If you are normally fixing in formalin for 24-48 hours, then
you can take your specimens directly to the microwave processor and see
no difference from specimens processed conventionally.  On the other
hand, if you are not able to fix in formalin this long, you should
consider adding a step in a microwave fixative between your primary
fixation and the microwave processing.  Please contact me back-channel
if you would like to have more specific details regarding our product,
Preserve*, which was developed for exactly this purpose.

Best regards,
Steven E. Slap, Vice-President
