Water Baths
Water baths are laboratory equipment designed for maintaining a constant temperature of samples by immersing them in a water-filled chamber. These baths are commonly used in various scientific and medical applications for activities such as incubation, heating, and thawing. Here are key features and information about water baths:
-
Principle of Operation:
- Water baths work on the principle of conduction, where heat is transferred from the water to the sample containers. The water bath maintains a stable temperature, providing a controlled environment for samples.

Temperature Control:
- Water baths come with temperature control features, allowing users to set and maintain a specific temperature for their experiments or processes. The temperature is regulated by a thermostat or a digital temperature controller.
