Description
Watch glass PTFE, Ø 50 mm is a laboratory watch glass manufactured from polytetrafluoroethylene for use where chemical resistance and a non-stick surface are required. With an outer diameter of 50 mm it is sized for small-scale weighing, covering beakers or evaporating dishes, and observing samples under corrosive conditions. PTFE construction offers broad inertness toward many acids, bases and organic solvents, helping to limit vessel attack and cross-contamination compared with conventional glass when aggressive media are handled. The smooth fluoropolymer surface also aids cleaning and sample recovery, which supports reproducible work in research, quality-control and teaching laboratories. Supplied as a single piece from manufacturer Vitlab, this compact watch glass fits micro-scale tasks, balance pans and small reaction setups that need a chemically durable cover or weighing surface. Its 50 mm diameter keeps the footprint modest while still providing a practical working area. The component is intended for routine laboratory operations involving reactive substances where a PTFE watch glass of defined diameter is specified.
This article is part of Watch glasses & crystallising dishes, in Dishes, crucibles & porcelain.

Questions about Watch glass, PTFE, diameter 50 mm
What is this article?
Watch glass, PTFE, diameter 50 mm is the article on this page. Luminix Health distributes Vitlab 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.
