Good morning,
I am looking to get some info on flash freezing for frozen sections. Currently we use the can freeze it spray, along with the heat extractor in the cryostat, to do it faster, however I am concerned with safety and feel that this poses a huge exposure risk. We have found that using the heat extractor alone is not fast enough in cases with multiple specimens and tend to get freeze artifact, most likely due to overzealous pathologists. What is everyone else using? Do you use the canned spray? 
Thanks
