Description
Stonylab
Watch Glass
A watch glass is a type of glass surface dish commonly used in chemical laboratories. It is a circular, concave piece of glass with a slight convex shape. The design resembles the shape of a shallow watch glass, hence the name.
Advantages
Stonylab watch glasses are made of borosilicate glass, providing them with good chemical resistance and thermal stability.
They can withstand moderate temperature changes and are compatible with common laboratory solvents, acids, and bases.
Design Features
Shape: Watch glasses are circular with a convex-concave shape, preventing moisture buildup.
Rim: Watch glasses feature a rounded rim for a safe and comfortable grip, reducing the risk of injuries from sharp edges.
Transparency: Our watch glass is high-transparent and provides clear visibility of the contents or samples placed beneath it.
Multiple Applications
Versatile Covers for Lab Containers
Watch glasses are essential covers for beakers, flasks, and containers, preventing evaporation of volatile substances and reducing contamination risks. Their concave shape enables convenient stacking and nesting during storage.
Evaporation and Sample Handling
They can be used for evaporating small volumes of liquid by placing the watch glass on a heated surface, promoting more efficient evaporation.
Watch glasses are also useful for holding small amounts of solids or liquids during weighing or transferring samples.
