Description
The Cometek 3" (7.5cm) Glass Watch Glasses offer a reliable, multi-purpose solution for core laboratory tasks. This comprehensive classroom set contains twelve concave glass covers specifically designed to fit over standard beakers and flasks to minimize dust contamination and prevent liquid splashing. Each piece is engineered with a robust 2.0mm thickness to offer improved resistance against shattering compared to standard thin glass. Beyond functioning as protective lids, their smooth concave geometry makes them highly effective as small scale evaporation dishes for growing seed crystals, or as stable platforms to hold chemical specimens under low-powered microscopes. Finished with professionally polished surfaces and cleanly ground edges, these durable watch glasses maximize handling safety, making them a cornerstone option for school science classrooms and industrial labs alike.
Features
:- Concave Shape Utility: Domed structure helps contain vapors or safely cradle small solids, powders, or liquids during observations.
- 2.0mm Thick Profile: Substantial glass wall density increases structural stability and helps prevent accidental breakage.
- Optically Clear Polishing: Highly clear glass allows unimpeded visual inspection and light transmission for micro-examinations.
- Bulk Laboratory Pack: Comes in a convenient 12-piece bundle to fully equip multiple student work benches or testing stations.
Applications
:- Preventing volatile loss, particle entry, and environmental cross-contamination during active reactions.
- Evaporating minimal liquid fractions off mixtures to cultivate salt or seed crystal structures.
- Carrying small geological, biological, or chemical materials underneath optical lenses.
- Providing budget-friendly, reusable, and safe testing apparatus for foundational chemistry or physics studies.
