Description
Watch glass made of polytetrafluoroethylene (PTFE) with an outer diameter of 125 mm provides a chemically resistant, shallow concave surface for covering beakers, evaporating small liquid volumes or holding samples during weighing and observation. PTFE construction offers broad inertness toward many laboratory reagents and supports repeated use under typical bench conditions. The 125 mm diameter suits medium-sized vessels and balances common in analytical and preparative work. This watch glass from manufacturer Vitlab is supplied as a single piece and fits standard laboratory workflows involving sample protection, dust exclusion or short-term evaporation steps. Its smooth PTFE surface facilitates cleaning and reduces adhesion of residues compared with glass alternatives in certain applications. Suitable for general chemistry, materials testing and routine sample handling where a durable, non-glass watch glass of defined diameter is required.
This article is part of Watch glasses & crystallising dishes, in Dishes, crucibles & porcelain.

Questions about Watch glass, PTFE, diameter 125 mm
What is this article?
Watch glass, PTFE, diameter 125 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.
