A Cooling Water Bath is an essential laboratory equipment used to maintain samples at low and stable temperatures. Whether it is for chemical reactions, biological studies, or pharmaceutical testing, a cooling water bath ensures precise thermal control, making it a vital tool across research, industrial, and quality-control environments.
What is a Cooling Water Bath?
A cooling water bath is a temperature-controlled unit that circulates cooled water around samples to maintain low temperatures typically ranging from -10°C to 100°C, depending on the model. It is commonly used in laboratories for:
- Enzyme studies
- Protein crystallization
- Pharmaceutical sample testing
- Chemical reaction control
- Cold storage of biological samples
How Does a Cooling Water Bath Work?
A cooling water bath operates on a combination of refrigeration and circulation:
1. Refrigeration System
A built-in cooling compressor lowers the water temperature. Refrigerants are circulated through coils, absorbing heat from the bath water.
2. Heater (Optional)
Some models include a heating coil to offer a wider temperature range, enabling both cooling and moderate heating.
3. Temperature Controller
Digital microprocessor controllers ensure accurate temperature regulation, typically within ±0.5°C.
4. Water Circulation
A strong pump circulates the water evenly, preventing temperature gradients and ensuring uniform cooling.
