Description
Concave beaker covers (also known as watch glasses) made with quality glass. Each cover features ground edges & polished surfaces for safe handling. The 2.0mm glass thick construction resists shattering. Can be used for a variety of laboratory functions – ideal for covering beakers and flasks, but can also be used to hold small samples for observation under a low powered microscope, or evaporating liquids off of samples (i.e. growing seed crystals).
