SYMBOLS ON UNIT

The following symbols are attached to the unit. The table describes the meaning of the symbols.

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;
o
■ Temperature 5 C to 40
■ Maximum relative humidity 80 % for temperature up to 31
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 -80 °C - -70 °C
plasma: 2-3 months at -80 °C
■ The effective storage period depends on the sample condition and storage temperature.
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
