Description
Porcelain pestle with 30 mm diameter and 135 mm length supports efficient manual grinding and mixing of laboratory samples in matching mortars. An unglazed grinding surface maximises friction for thorough trituration of crystalline solids, powders and other dry materials commonly processed in analytical, pharmaceutical and materials laboratories. The porcelain construction provides the chemical durability expected of ceramic labware and avoids metallic abrasion of the sample. At 135 mm overall length and Ø 30 mm head size, the pestle offers a larger working face than smaller models, suited to medium sample loads and steady hand pressure. Net weight is 0,139 kg, giving a balanced feel during prolonged grinding. This unglazed porcelain pestle from manufacturer Witeg is supplied as a single piece for routine sample preparation, homogenisation prior to dissolution or extraction, and teaching demonstrations. Use with a compatible unglazed porcelain mortar to maintain grinding performance and minimise contamination of the prepared material.
This article is part of Mortars & pestles, in Dishes, crucibles & porcelain.

Questions about Pestle Ø 30mm length 135mm unglazed
What is this article?
Pestle Ø 30mm length 135mm unglazed is the article on this page. Luminix Health distributes Witeg 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.
