A laboratory water bath is used to heat samples in the lab. Some
applications include maintaining cell lines or heating flammable chemicals that
might combust if exposed to open flame. A water bath generally consists of a
heating unit, a stainless-steel chamber that holds the water and samples, and a
control interface. Different types of water baths offer additional
functionality such as a circulating water bath that keep a more even
temperature or a shaking water bath that keeps the samples in motion while they
are heated.
