CH-100, Heating/Cooling Dry Block


CH-100 is the result of combining two popular Biosan instruments:

  1. Heating Dry block and
  2. Cooling Dry block thermostat

The combined construction of aluminium block and Peltier element module cooled with the forced ventilation radiator provides fast  changing of the cooling and heating modes.

CH-100 is a very effective instrument of sample preparation during enzyme reactions,  hybridization reactions, DNA analysis.

Microprocessor controlled time and temperature. Simultaneous indication of set and actual  temperature and time.

Blocks (built in) capacity:
1) with CH-1 block for 20 x 0.5 ml + 12 x 1.5 ml microtubes;
2) with CH-2 block for 20 x 1.5 ml microtubes;
3) with CH-3 block for 20 x 2 ml microtubes.
