Intended use

Vestfrost biomedical freezers are designed to provide reliable temperature stability and precision
and ensure an ideal cold temperature storage for sensitive items is achieved� The products are
designed for the following operating ranges:
Models
Temperature range
Fabric Set Point
Ambient Temperature
Relative humidity
Number of probes
WARNING: This unit is not a "rapid-freeze" device� Freezing large quantities of liquid,
or high-water content items, will temporarily increase the chamber temperature and will cause
the compressors to operate for a prolonged time period� Avoid opening the door for extended
time periods since chamber temperature air will escape rapidly� Also, keep the inner doors closed
as much as possible� When room air, which is higher in humidity, replaces chamber air, frost may
develop in the chamber more rapidly�
