Description
Lid for crucibles with 30 mm diameter is a glazed porcelain cover made to fit matching porcelain crucibles of that diameter in laboratory heating and sample-protection work. The glazed porcelain surface provides a smooth, durable finish consistent with standard porcelain crucible ware and supports clean placement and removal during thermal procedures. Using a dedicated lid helps limit contamination, reduce spatter loss, and moderate evaporation when samples are heated, ignited, or held at elevated temperature. The component is intended as a complementary accessory for 30 mm crucibles rather than a standalone vessel, enabling laboratories to complete or replace lid sets without changing the underlying crucible inventory. Packed in cartons of five pieces, the format suits routine replenishment for teaching laboratories, analytical benches, and multi-sample workflows. Produced by Marienfeld, this glazed porcelain lid offers a straightforward fitment option for 30 mm diameter crucibles used in general chemistry, materials preparation, and quality-control environments where porcelain crucible systems are standard equipment.
This article is part of Crucibles, in Dishes, crucibles & porcelain.

Questions about Lids for crucibles of 30 mm diameter,
What is this article?
Lids for crucibles of 30 mm diameter, is the article on this page. Luminix Health distributes Marienfeld 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.
