Water/Cold Bath DWB20-S (CAT#: STEM-BC-2373-ZJF)

The DWB20-S is a laboratory water bath or cooling circulator designed for precise temperature-controlled incubation, cooling, and sample conditioning. An integrated thermostat provides stable temperature control over a defined range, from below ambient to elevated temperatures. The inner chamber is typically fabricated from stainless steel, providing corrosion resistance and ease of decontamination. An LED or LCD display provides clear readout of set and actual temperatures for continuous monitoring. The unit includes an independent overtemperature protection circuit to prevent sample damage during prolonged operation. For cooling models, a refrigeration or Peltier system provides rapid temperature reduction below ambient levels. The circulation pump maintains uniform temperature distribution throughout the bath volume. It is compatible with standard laboratory vessels including beakers, flasks, tubes, and sample bags. Applications include enzyme reactions, hybridization, PCR, protein digestion, and sample warming or cooling. This instrument is widely used in molecular biology, biochemistry, cell biology, and clinical diagnostics.
