Agate is a variety of quartz used for producing laboratory mortars. Agate mortars are ideal for preparing samples of high purity by mixing and grinding semi-hard or hard substances:

• High hardness (7 in Mohs scale) and extreme resistance to abrasion avoiding sample contamination by particles detached from the mortar
• High density (2.6g/cm3), it means, low porosity, minimizing sample lost and reducing cross contamination between different samples.
• High resistance to chemical agents’ action(acids, base, organic solvents, etc.) except from the action of hydrofluoric acid and aqua regia.

Our agate mortars are octagonal shape. The agate mortar are polished inside without defects as well as the pestle. The external surface is uniformly sanding. Mortars are supplied complete with pestle. Pestle can also be purchased separately. Please call for details.
