Our Mohs Lab is CAP accredited. Every seven days of use, cryostats are shut
down. Once machine has been cleaned and dried we use Cavi-wipes(super
Sani-Cloth from PDI Inc.) We then document disinfection date on QC Log. We
have three cryostats, we rotate a cryostat a week for disinfecting purposes. We
added this to our Equipment: Cryostats/Microtomes policy.
Hope this helps.

Subject: Re: [Histonet] Cryostat with UV disinfection
For those of you that are CAP accredited, and use a cryostat with UV
disinfection, how do you get around the CAP requirement listed below? We were
told the UV disinfection did not replace wiping down with a tuberculocidal
disinfectant at room temp. Do you have an approved tuberculocidal disinfectant
that will work at cryostat temps? Curious minds would like to know!
ANP.23410 Cryostat DecontaminationPhase II
There is a written procedure for the decontamination of the cryostat at defined
intervals, and under defined circumstances, and decontamination records are
evident.
NOTE: The cryostat must be defrosted and decontaminated by wiping all exposed
surfaces with tuberculocidal disinfectant. The cryostat should be at room
temperature during decontamination unless otherwise specified by the
manufacturer. This should be done at an interval appropriate for the
institution; this must be weekly for instruments used daily. Trimmings and
sections of tissue that accumulate inside the cryostat must be removed during
decontamination. Although not a requirement, steel mesh gloves should be worn
when changing knife blades.
