Spray disinfection with Leica Cryofect
For practical spray disinfection, we recommend
Leica Cryofect which is fully effective at tem-
peratures in the negative range down to -20 °C.
Set chamber temperature -20 °C or warmer.
Remove specimens from the chamber and
store safely.
Carefully remove knife / blade from knife
holder.
Remove section waste tray from cryocham-
ber and empty.
Remove remaining section waste from cryo-
chamber.
Working accessories (brushes, specimen
holders etc.) can be disinfected inside the
cryochamber.
Once the selected chamber temperature has
been reached, spray Leica Cryofect on the
surfaces and accessories to be disinfected.
Allow to soak for 15 minutes.
Use paper towels or another type of
disposable cleaning cloths to wipe up
disinfectant and remaining section waste.
Dispose of paper towels together with sec-
tion waste.
If previously altered, set chamber tempera-
ture back to its former value.
Put specimens back into the cryochamber.
