It features a smooth surface and excellent transparency for easy observation of experimental phenomena. With superior shatter resistance, it is sturdy, durable, and long-lasting. Used for evaporating liquids, it increases the liquid's surface area to accelerate evaporation. As a lid, it covers evaporating dishes or beakers to prevent dust ingress. As a container, it temporarily holds solid or liquid reagents. It also serves as a carrier for pH paper, preventing acid or alkali solutions dripped onto the paper from corroding the lab bench truly versatile.
