Watch Glass, 2"

A Watch Glass of 2-inch diameter is a circular, slightly concave piece of laboratory glassware primarily used for evaporating liquids, weighing solids, and as a cover for beakers or flasks to prevent contamination or evaporation. These watch glasses are typically made from borosilicate glass, known for its heat resistance and chemical durability.

Specifications and features:

Diameter: approximately 2 inches (50.8 mm).

Thickness: typically around 2 mm.

Material: clear, high-quality borosilicate glass resistant to thermal shock.

Concave shape prevents solid samples from falling off and helps condensation return to the container.

Polished or fire-ground edges for safe handling.

Used for evaporating liquids gently, holding powders for weighing, as a lid for beakers, or for observing chemical reactions.

Durable and reusable for laboratory use.

Watch glasses provide excellent visibility and are essential for many standard lab processes including sample preparation, crystallization observation, and temporary storage of liquids or solids. The generated image shows a clear, round, slightly concave laboratory watch glass with polished edges
