It's not safe to use any type of spray in a cryostat. It creates aerosols
of who knows what (tuberculosis) from potentially infectious patient
biopsies. I would not recommend it, just as a universal precaution.

There are non flammable sprays available. We got the recall notice and switched
our old inventory out. I found 3 different histology specific sprays. The
electronic industry offers some as well. Another option is just using LN2

I have to agree with Terri. I also believe that CAP is going to be putting
in regulations forbidding the use of freeze sprays in cryostats soon (at
least I think I heard a rumor about this).
Anyway another useful item is liquid nitrogen if you really need a quick
freeze. Dip a brush into the
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

We received the same letter months ago. 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.

We are purchasing two of their newer UV cryostats and they were adamant that we
use a non flammable freezing spray because it can damage the UV unit and have
potential for exploding.

I just received a letter from Leica Biosystems where they are prohibiting the
usage of flammable
freezing sprays in their cryostats. What are others using in their cryostats
to instantly freeze specimens?
Thank you.
