Laboratory Water Bath is a piece of equipment that is used in scientific research laboratories to heat or cool substances in a controlled and uniform manner. The equipment consists of a container filled with water, which is heated or cooled using an electric or gas-based heating element or a refrigeration unit. The temperature of the water bath can be set and monitored using a digital or analog controller, and the bath may also include a circulation system to keep the temperature consistent throughout the container. Laboratory Water Bath is useful in experiments that require precise temperature controls, such as those performed in molecular biology or analytical chemistry.
