Agate is the preferred material for mortars and pestles for laboratory use. It is harder than glass and porcelain and has a very fine grain structure, so a previous grinding product can be cleaned out with ease to reduce cross-contamination.
Do not use agate with liquid nitrogen as it is liable to crack.
Sterilise with alcohol or other chemical, heat could damage the mortar.
Because of their natural origin, the agate mortars and pestles may vary slightly in appearance from the picture.
