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.
