9.  OPERATION OF CRYOSTAT 

 

9.1  UV-C 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 MNT can be equipped with an UV-C light source that can either be 

automatically activated (see section 7.3) or manually activated. 

The default setting for the UV-C light duration and the automatic deactivation is set to 

30 minutes. The timer can be set by an authorized service technician. 

 
 

 

i

 

For safety reasons UV-C light will be deactivated upon opening of 

the lid of the cryochamber. The UV-C 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. 

 
 
 

9.1.1 INSTALLATION INSTRUCTIONS FOR UV LAMP - CRYOSTAT 

Please follow the respective steps and pay attention to the relevant instructions. 

Touch the UV lamp never directly on the glass, since this reduces the durability may be
