9. OPERATION OF CRYOSTAT
9.1 UVC DISINFECTION
[only applicable to instruments equipped with this feature]
UV-C radiation at 254 nm has an intense germicidal effect. Microorganisms, such as
viruses, bacteria, fungi and yeasts are effectively destroyed in the area accessible to UV
light without the addition of chemicals.
The cryostat MEV can be equipped with an UVC light source that can either request
activation in defined periods (see section 7.3) or is manually activated.
The default setting for the UVC light duration and the automatic deactivation is set to
30 minutes. The timer can be set by an authorized service technician.

For safety reasons UVC light will be deactivated upon opening of the
lid of the cryochamber. The UVC disinfection will be aborted and has
to be activated again for surface disinfection.
The default setting for automatic deactivation is set to 30 minutes.
The timer can be set by an authorized service technician.
