Description
Rotilabo® watch glass in PTFE with a diameter of Ø 75 mm is a mid-size laboratory dish intended for covering vessels, assisting crystallisation tasks, and presenting small to medium sample amounts during bench work. PTFE provides a robust, chemically resistant working surface for many standard laboratory procedures where a non-glass watch glass is desired. Supplied as 1 pc(s) and weighing 0,030 kg, the piece is straightforward to handle, rinse, and return to storage with other dishes and evaporating accessories. It can act as a temporary cover or shallow support during weighing, observation of residues, and intermediate sample holding. This ROTH SELECTION Rotilabo® watch glass offers a clearly specified Ø 75 mm format that pairs well with common beakers and crystallisation setups. Laboratories use such dishes within sample-preparation sequences, teaching demonstrations, and routine analytical support. The balanced diameter suits workflows that need more surface area than a 50 mm glass while remaining compact enough for crowded benches and shared labware drawers in research and quality-control environments.

Questions about Rotilabo®-watch glass, PTFE, Ø 75 mm, 1 unit(s)
What is this article?
Rotilabo®-watch glass, PTFE, Ø 75 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.
