Mortars and Pestles
Tools used to grind and crush substances into fine powders or pastes, Mortars are bowl-shaped containers and pestles are heavy, rod-shaped tools. Commonly sold as sets but also available separately, mortar and pestle sets may include mortars, pestles, adapters, housings, or other items in several materials.
Mortar and pestle implements have been used since ancient times to crush and grind substances. Mortars can be made of hard materials like wood, metal, ceramic, or hard stone such as granite or marble. Pestles are held in the hand and usually have a tapered, club-like shape. A wet or dry substance is placed in the mortar and the pestle is pressed against it and rotated until the material is pulverized.
What Is the Best Material for a Mortar and Pestle?
The implements must be made of materials that are hard enough to crush the substance without wearing away, but they cannot be brittle or break from the pressure of manipulation. The material should also be cohesive to reduce chipping and non-porous to avoid absorbing or trapping substances. Some rough porcelain mortars and pestles can reduce substances to very fine powders, but are brittle and stain more easily. Porcelain mortars can be pre-conditioned by grinding sand in them to produce a rougher surface. Glass mortars and pestles are stain-resistant and suitable for liquids, but are fragile and do not grind as finely as ceramic sets. Metal mortars and pestles are popular for food preparation.
Mortars and pestles are commonly used to grind and mix substances for dilution, to mask negative qualities, or to add volume to facilitate handling. Drugs can also be finely ground when not available in liquid form, and supplements can be processed to for addition to parenteral nutrition.

Electron Microscopy Sciences Dounce Tissue Grinder, 15 ml, 22 mmx 94 mm Mortor, 210 mm OAL
This grinderis ideal for soft tissue and will retain a high percentage of cell nuclei and mitochondria in soft tissues from cell cultures. When in use, the pestle ball is encircled in liquid, which avoids heat buildup by reducing friction. The initial grinding is performed using the "loose" pestle. The grinding process is completed using the "tight" pestle. This grinder is used by moving the pestle up and down, and work best with cell suspensions or very soft tissues. The mortar has a large reservoir and pouring lip and is supplied with "loose” and "tight” pestles. Made of Wheaton 33 low extractable borosilicate glass. Autoclavable.
Size: 15 ml
Mortor: 22 mmx 94 mm
OAL: 210 mm
Electron Microscopy Sciences Potter-Elvehjem Tissue Grinder, 10 ml, 16 mmx 74 mm Mortor, 219 mm OAL
These grinder are precisely constructed with completely interchangeable parts to allow easier cleaning or replacement of damaged mortars. Ideal for tissue homogenates and other similar applications. The Teflon pestle is for soft tissues such as brain or liver. The stainless steel rod is 0.25" (6.3 mm) diameter. The grinding chamber clearance is 0.004" to 0.006' (0.1 to 0.15 mm). This unit is autoclavable and can be used for power homogenization as with overhead stirrer.

Research Products International Corp SpiralPestle Grinder Kit, 100 each pestle and 1.5ml micro-tube
Unique SpiralPestle Grinder features screw-like pestle to homogenize culture cells, small tissue samples, centrifugal pellets, precipitates and other soft solids. SpiralPestle Grinder actively rotates and conveniently draws 10-100 mg of sample suspended in 200-500ul of extraction solution downward to bottom of 1.5 ml conical micro-tubes.
Ideal pestle disperses soft plant or animal tissues quickly and effectively by macerating and mechanically dispersing samples between the wall of the pestle and micro-tube. Adding glass grinding beads can further enhance sample grinding and its recommended for efficient cell lysis of tissues and microorganisms. Suppied 100 each (pestle and 1.5 ml micro-tube) plus black rubber coupler for use with BioVortexer.
