Watch Glasses

The watch glass is an essential laboratory accessory, designed with a concave-convex shape that offers resistance to various chemical liquids. Primarily made from soda glass, this product stands out for its chemical and physical properties, making it ideal for procedures that do not require withstanding extreme thermal loads or sudden temperature changes.

Main Uses:

    • Container Covering: Acts as a non-airtight lid to protect against environmental contaminants.
    • Evaporation and Crystallization: Used in educational settings to facilitate direct observation of processes such as crystallization or precipitate formation.
    • Substance Support: Ideal for placing small amounts of solid or wet substances, whether for mixing, weighing, or examining under a stereo microscope.

In weighing processes, it is important to perform an initial tare. Place the watch glass on the balance and zero it before measuring the desired substance, ensuring accurate results.

This versatile instrument is an indispensable resource in both professional and educational laboratories, facilitating a wide range of scientific applications. Its practical and efficient design makes it an excellent choice for any environment requiring precision and reliability.
