ENVIRONMENTAL CONDITIONS
This equipment is designed to be safe at least under the following conditions (based on the IEC
61010-1):
■ Indoor use;
■ Altitude up to 2000 m;
■ Ambient temperature 5 o C to 40 o C;
■ Maximum relative humidity 80 % for temperature up to 31 o C decreasing linearly to 50 % relative
humidity at 40
o
C;
■ Mains supply voltage fluctuations up to ±10 % of the nominal voltage;
■ Transient overvoltages up to the levels of OVERVOLTAGE CATEGORY II;
■ Temporary OVERVOLTAGES occurring on the mains supply;
■ Applicable pollution degree of the intended environment (POLUTION DEGREE 2 in most cases);
INTENDED USE AND PRECAUTIONS
This equipment is designed for low temperature storage of human cells, organs, plasma and DNAs.
Temperature and duration of storage:
cells: 1month - 1year at -80 °C
organs: 11months at -80 °C
DNA: Long term (8 years) at -70 - -80 °C
plasma: 2-3 months at -80 °C
■ The effective storage period depends on the sample condition and storage temperature. It is
necessary to determine the storage temperature and period suitable for the purpose.
■ For the live cells, the lower storage temperature should be required for long term storage. It is
recommended to store the live cells at -130
o C or lower.
