Description
BOLA watch glass, 125 mm, PTFE, machined design is a convex laboratory dish sized for broader weighing, covering and sample-handling tasks. Outer diameter is 125 mm and height is 12 mm, giving a generous surface for larger portions, residues or vessel covers compared with smaller PTFE watch glasses. The article is made from polytetrafluoroethylene (PTFE) in a machined design, so geometry and material are consistent with demanding bench work that benefits from an inert polymer surface. Net weight is 0,09 kg per piece, supplied as 1 pc for flexible stocking. In practice these BOLA watch glasses (Bohlender) function as classic Uhrglasschalen and Uhrgläser for temporary holding, light evaporation and covering steps in research, quality control and teaching laboratories. The convex form supports drainage and transfer of solids, while the documented diameter, height and mass simplify selection against existing glassware, balances and storage systems. PTFE construction keeps the contact surface free of glass-related constraints for many routine media. This 125 mm machined variant completes the larger end of the range for laboratories that standardise on durable PTFE watch-glass dishes across multiple diameters.
This article is part of Watch glasses & crystallising dishes, in Dishes, crucibles & porcelain.

Questions about BOLA Watch Dishes, 125 mm PTFE, turned
What is this article?
BOLA Watch Dishes, 125 mm PTFE, turned is the article on this page. Luminix Health distributes Bohlender 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.
