The 2.0mm thick glass construction resists shattering. This 12-pack set includes twelve covers, each measuring 4 inches (10cm) in diameter. They can be used for a variety of laboratory functions - ideal for covering beakers and flasks, holding small samples for observation under a low-powered microscope, or evaporating liquids off of samples (i.e., growing seed crystals).
