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 apparance from the picture.
Physical properties of agate
Chemical composition: 99.9% Si02, which makes it a quartz species, with trace contaminants alumina and iron oxide common
Crystal system: hexagonal-R; 32 (trigonal-trapezohedral)
Crystal habit: usually as banded or layered botryoidal masses with microfibrous structure
Zoning: colour banding and layers of inclusions are common
Specific gravity: 2.57 - 2.64
Mohs hardness: 6.5-7
Index of refraction: 1.53-1.55
Birefringence: weak, 0.005 to 0.009
Enhanced grinding capability for tough samples.
The pestle tips of the new BMP ultra tissue grinders have been vitrified using a proprietary silica casting process. The result is a glass-like abrasive surface, which provides a more aggressive grinding action, to enable efficient processing of difficult and fibrous samples.
BMP ultra tissue grinders incorporate the same patented closed system as our standard grinders.
Available in 15mL and 50mL sizes, supplied gamma sterilised in an easy-to-open Tyvek package with an extra cap for storage and transport plus a patient identification label for traceability.
Glass with PTFE pestle
These homogenisers are made of borosilicate glass with PTFE pestles. Pestle shaft is stainless steel, diameter 6.5 mm. Pestle clearance with mortar is 0.15 - 0.25 mm. Volumes stated are working volumes. Ideal for small amounts of tissue. Serrated pestle can be used on tough materials such as tumours.
