Description
Watch glass, PTFE, 100 mm is a laboratory cover dish intended for protecting open vessels during routine chemical work. Formed isostatically from pure PTFE, it is completely resistant and chemically inert, so it does not interact with common reagents or solvents. The material is FDA-compliant and remains usable up to 280 °C, supporting both ambient and moderately heated procedures. With a diameter of 100 mm it is well suited to covering typical beakers and similar glassware, helping to limit contamination, reduce evaporation and keep dust away from samples. The piece is supplied as one unit with a net weight of 0,100 kg and originates from manufacturer Labbox. Its inert PTFE surface and stable moulded shape make it practical for general chemistry, analytical preparation, teaching laboratories and other workflows where a non-reactive, heat-tolerant cover is required. The watch glass can be cleaned and reused under normal laboratory conditions without loss of chemical resistance, offering a durable alternative to glass covers when aggressive media or elevated temperatures are involved.
This article is part of Watch glasses & crystallising dishes, in Dishes, crucibles & porcelain.

Questions about Watch glass dish, PTFE, 100 mm
What is this article?
Watch glass dish, PTFE, 100 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.
