A watch glass is a shallow, concave piece of glassware commonly used in laboratories for various tasks, such as holding small quantities of substances, evaporating liquids, covering beakers, and conducting simple experiments. Its versatility and simplicity make it a staple in both educational and professional laboratory settings.
Applications:
Evaporation: Used to evaporate small amounts of liquid solutions by spreading them over the surface of the watch glass. The wide surface area helps accelerate evaporation.
Covering Containers: Often used as a cover for evaporating dishes or beakers to prevent contamination by dust while allowing controlled evaporation.
Holding Samples: Ideal for holding small samples of solids, powders, or liquids during experiments or while weighing them on a balance.
Carrying pH Paper: Can be used as a holder for pH paper to prevent acidic or alkaline liquids from corroding the laboratory bench when dropped onto the paper.
Observation: Suitable for observing small chemical reactions or biological samples under a microscope or simply by visual inspection.
Simple Heating: Can be used to gently heat small amounts of substances, such as when drying a sample in an oven or under a heat lamp.
