Evaporating dishes are used to hold samples under high heat conditions. This video demonstrates.

Types of Evaporating Dishes

This labware can be found in shallow (low) and standard (high) form. In general, shallow form dishes are 2/3rds the height of standard form, providing greater surface area. The walls may be gently sloped or vertical.

Evaporating Dish Specifications

Evaporating dishes are commonly small, with volume capacity ranges of 25 ml (or less) to 400 ml.

Ceramic, glass, plastic, and metal (platinum) are common materials. Ceramic and metal have the highest heat tolerances; platinum is costly; glass is transparent; plastic may be less prone to breakage, chemically inert, non-contaminating, and easier to clean.

Features and Applications

  • Bottoms may be rounded or flat.
  • Limited use labware can be disposable.
  • A few dishes have no pouring lip and may be called crystalizing dishes.
  • Evaporating dishes, usually made from glass, can be graduated or marked with regular measurement intervals.
  • Handles can be extended from the lips of this labware, causing it to be renamed casserole dishes.
