My question is why would you ever want to use an aerosol in the cryostat, taking a chance on aerosolizing some nasty bug? Is the 30 seconds you save in using freezing spray worth the exposure to TB or goodness-knows-what? We use a simple metal heat extractor (comes standard in our Leicas) and place it on top of the freezing block to accelerate the process. We never have issues with turn around times. For me, no freezing spray. Ever.

We changed to a non-flammable spray. It is called STATFREEZE, we purchase it from STATLAB. The catalog number is SL202/134a. Be careful if you order it because they also sell a product called STATFREEZE that is flammable. Valerie Hannen,MLT(ASCP),HTL,SU (FL) Section Chief, Histology Parrish Medical Center 951 N.
