Description
Watch glass, PTFE, 200 mm is a laboratory cover dish intended for securely covering beakers and similar vessels during sample handling, evaporation steps and general bench work. Isostatically moulded from pure PTFE, it is chemically inert and fully resistant to aggressive reagents, supporting use where glass or metal covers are unsuitable. The material is FDA-compliant and remains serviceable up to 280 °C, allowing both ambient and elevated-temperature applications. Its 200 mm diameter offers generous coverage for larger glassware while the smooth PTFE surface resists adhesion and simplifies cleaning between runs. Supplied as a single piece with a net weight of 0,100 kg, this watch glass from manufacturer Labbox suits analytical, research and industrial laboratories that need durable, non-reactive covering solutions. The inert polymer construction helps minimise contamination risk and maintains dimensional stability under typical laboratory conditions. Categories such as watch glasses and cover dishes benefit from this robust PTFE format whenever chemical resistance and thermal tolerance are essential for reliable daily workflows.

Questions about Watch glass dish, PTFE, 200 mm
What is this article?
Watch glass dish, PTFE, 200 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 Labware.
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.
