Description
PTFE watch glasses Ø 125 mm are laboratory watch dishes manufactured from polytetrafluoroethylene for chemical handling, sample preparation and general wet-chemistry work. With an outer diameter of 125 mm, the white dishes are supplied without a foot, giving a simple, stable profile that sits flat on the bench or under a fume hood. PTFE offers broad chemical resistance and a non-stick surface, making these watch glasses suitable for evaporations, weighing of corrosive solids, covering beakers and temporary storage of aggressive reagents where glass may be less appropriate. The smooth, inert surface supports easy cleaning and reduces carry-over between steps. Each pack contains 10 pc(s), providing a practical stock quantity for routine laboratory use. Net weight is 0,078 kg per unit. These PTFE watch glasses from manufacturer Witeg fit standard workflows in analytical, synthesis and teaching laboratories that require durable, chemically inert open dishes in a defined 125 mm diameter. They complement glassware sets where PTFE contact surfaces are preferred for demanding media.

Questions about Watch glasses PTFE Ø 125 mm
What is this article?
Watch glasses PTFE Ø 125 mm is the article on this page. Luminix Health distributes Witeg 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.
