Description
Pestle 135×30 mm (length × diameter) is a porcelain laboratory grinding implement designed for efficient trituration in mortar-based sample preparation. With an overall length of 135 mm and a 30 mm grinding-surface diameter at the head, it offers a larger contact area suited to medium-capacity mortars and higher sample loads. The head is finished with a rough grinding face that works against the unglazed interior of porcelain mortars to reduce particle size of solids, powders and crystalline substances. Constructed from porcelain throughout, the pestle delivers mechanical strength and chemical resistance for everyday laboratory use. Supplied as a pack of 2 pieces, it supports multi-user benches or spare inventory. This pestle from manufacturer Marienfeld is appropriate for analytical chemistry, pharmaceutical compounding, materials testing and educational laboratories that depend on manual grinding. Match the 30 mm head diameter to a compatible mortar to ensure stable handling and reproducible homogenisation prior to weighing, extraction or further analysis.
This article is part of Mortars & pestles, in Dishes, crucibles & porcelain.

Questions about Pestles 135x30 mm (length x diameter),
What is this article?
Pestles 135x30 mm (length x diameter), is the article on this page. Luminix Health distributes Marienfeld for laboratory use. It sits in Mortars & pestles, inside Dishes, crucibles & porcelain, in Labware.
A mortar and pestle grind a solid by hand. Porcelain is the ordinary laboratory set. Agate and glass are chosen when the sample must not pick up porcelain dust. The unglazed grinding surface, not the glossy outside, does the work.
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.
