Watch Glass

Product Code : TVT-GP-10775

The Watch Glass is a concave glass dish used for evaporating liquids off samples, such as when growing seed crystals, and doubles conveniently as a beaker cover.

How It Works

The dish's shallow concave shape holds a small volume of liquid or a solid sample in a slight depression, exposing a large surface area to the air to encourage even evaporation — useful, for example, when growing seed crystals from a small volume of saturated solution or forming lenses of ice or other liquids. Because its diameter is designed to match common beaker openings, the same watch glass can also be inverted and placed over a beaker as a cover, keeping dust out while still allowing some evaporation or venting as needed.
