WATCH GLASS (Superior Quality)

• A Watch Glass is a round, concave glass dish used in chemistry for evaporation.
• Chemists use it to evaporate liquids, weigh solids, and cover beakers during sample preparation.
• It helps them observe the formation of precipitates or crystals.
• The available sizes are 3″ and 4″, and the pack sizes are 12pcs.

In a chemistry laboratory, a watch glass is a versatile piece of equipment with various applications. One common use for a watch glass is to cover an evaporating dish or beaker during the process of heating a liquid. This approach helps prevent splattering and contamination, while still allowing vapors to escape. Additionally, it can serve as a surface for observing and examining solid samples, as a lid for beakers to prevent contamination, and as a weighing platform for solids on a balance.

Due to its transparent and polished nature, a watch glass is also suitable for examining small substances under a microscope, making it a multi-functional tool in the chemistry lab.

In a chemistry lab, it provides practical benefits for both researchers and students. Its ability to cover vessels during heating not only prevents the loss of volatile substances but also helps avoid cross-contamination between different materials. Moreover, the watch glass’s transparent and clear surface enables easy visual observation of reactions or sample examination without the need for direct handling. This not only ensures safety in handling hazardous substances but also allows for precise measurement and observation during experiments.

Overall, the utilization of a watch glass in a chemistry lab is essential for various experimental and observational tasks. Its utility in covering vessels, protecting samples, and facilitating observation and measurement makes it a crucial tool for conducting experiments safely and effectively. Whether used in student demonstrations or professional research settings, the watch glass proves to be a valuable and versatile asset in the chemistry laboratory.
