Dry Blocks, Thermostats

TDB-120 is a traditional Biosan’s dry block thermostat for laboratory analysis. Thermostat is designed for maintaining constant temperature of samples in tubes inserted in the aluminium block sockets. Unprecedented high precision and uniformity of temperature over the block. TDB-120 is widely used for PCR–analysis.

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

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

• Heating Dry block and
• 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.
