Metal Laboratory Water Bath comes in a wide variety of shapes, sizes, and types to suit different requirements. The Laboratory Water Bath traditionally is a wide, cylindrical, usually metal container made of three or four basic parts. The Laboratory Water Bath is equipped with a handle, an outer container that holds the working liquid. The Metal Laboratory Water Bath is designed with an inner, smaller container that fits inside the outer one and which holds the material to be heated or cooked, and sometimes a base underneath.
