Description
Watch glass, PTFE, 125 mm is a laboratory cover dish designed for shielding beaker contents and other open vessels during everyday experimental work. Isostatically moulded from pure PTFE, the dish is fully chemically inert and highly resistant, ensuring compatibility with a wide range of laboratory chemicals. It is FDA-compliant and can be used at temperatures up to 280 °C, which suits both room-temperature handling and moderately heated steps. The 125 mm diameter provides effective coverage for medium-sized beakers, helping to control evaporation, exclude dust and reduce cross-contamination on the bench. Delivered as a single piece with a net weight of 0,100 kg, the product comes from manufacturer Labbox. The non-reactive PTFE construction and robust moulded form deliver dimensional stability and long service life under repeated thermal and chemical stress. This watch glass is a practical choice for general chemistry, sample preparation, teaching labs and any setting that benefits from an inert, heat-tolerant cover instead of conventional glass.

Questions about Watch glass dish, PTFE, 125 mm
What is this article?
Watch glass dish, PTFE, 125 mm is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Watch glasses & crystallising dishes, inside Dishes, crucibles & porcelain, in Matériel de laboratoire.
A watch glass is a shallow curved cover or a dish for drying a few grams. A crystallising dish is the flatter, wider dish a solution is left in while a solid comes out. Neither is volumetric. Diameter is the specification.
A dish is an open vessel for drying, evaporating or holding a solid. Porcelain and glazed ceramic take a higher temperature than borosilicate glass, which is why a crucible, not a beaker, goes into a furnace. A watch glass covers, or holds a small amount for drying. A mortar is for grinding. The temperature and the chemical, not the shape alone, choose the material. Laboratory ware of this family is listed under ISO laboratory ware.
