Description
Rotilabo® watch glass in PTFE with a diameter of Ø 50 mm is a compact laboratory dish for covering beakers, supporting small-scale crystallisation work, and handling modest sample portions on the bench. The PTFE construction offers a chemically resistant surface suited to many routine laboratory environments where glass alternatives are less preferred. With a unit weight of 0,015 kg and supplied as 1 pc, this watch glass is easy to place, clean, and store alongside other crystallisation dishes and evaporating labware. It serves as a simple lid or shallow vessel during weighing transfers, solvent observation, and short holding steps in sample preparation. From manufacturer ROTH SELECTION, the Rotilabo® line provides consistent geometry for everyday lab use. The Ø 50 mm format is convenient for smaller vessels and limited sample volumes, helping keep work areas organised within dishes, evaporating dishes, and mortar-related workflows. A practical consumable for teaching labs, research benches, and quality-control stations that require a durable PTFE watch glass in a clearly defined diameter.

Questions about Rotilabo®-watch glass, PTFE, Ø 50 mm, 1 unit(s)
What is this article?
Rotilabo®-watch glass, PTFE, Ø 50 mm, 1 unit(s) is the article on this page. Luminix Health distributes Carl Roth 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.
