Description
Lid Ø 35 mm porcelain for low-form crucibles is a glazed porcelain cover sized for low-form (NF) melting crucibles used in everyday laboratory heating work. With a diameter of 35 mm, it fits matching low-form crucibles to shield contents during ashing, ignition, drying or fusion steps, helping to reduce splash, dust ingress and sample loss. The glazed porcelain construction offers the chemical resistance and thermal behaviour expected of standard porcelain labware and is straightforward to clean after use. Net weight is 0,012 kg, so the lid remains convenient to handle with crucible tongs. Ideal for research, quality-control and educational laboratories that standardise on porcelain crucible sets, this accessory from manufacturer Witeg provides a dedicated 35 mm lid for the low-form series. It is supplied as a single piece and serves equally well as original equipment or as a replacement cover when an existing lid is damaged or missing.
This article is part of Crucibles, in Dishes, crucibles & porcelain.

Questions about Cover Ø 35 mm porcelain for crucibles LF
What is this article?
Cover Ø 35 mm porcelain for crucibles LF is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Crucibles, inside Dishes, crucibles & porcelain, in Labware.
A crucible holds a sample in a furnace or over a flame, at temperatures that would soften a borosilicate beaker. Porcelain, platinum and glazed ceramic are different articles. The form, tall or wide, decides how fast a sample dries or ashes.
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.
