Definition : Pitchers designed for the safe and easy handling of melted paraffin. These devices typically consist of a hollow thermal unit that is open at the top and a pouring pitcher appropriate for placement inside the thermal unit. The thermal unit consists of a cylindrical double-wall metallic (typically stainless steel) jacket enclosing an internal chamber, as well as a wire heating element coiled between the walls to ensure even temperature distribution. It also includes a thermostat to control the paraffin at the desired viscosity, a handle, and rubber legs at the bottom. The pouring pitcher is made of highly polished metal and a visible volume scale. Paraffin pitchers are used mainly in clinical laboratories for embedding tissues in exact amounts of paraffin (typically to perform histological studies) while maintaining a complete control of the procedure.
