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 SureStrain™ PolyPestile Dual-sided Pestle
The SureStrain Premium Cell Strainer is a fast and easy-to-use system for detaching, isolating and straining cells from clusters and tissues. A polypropylene frame supports a nylon mesh and an unique interlocking stackable design makes tiered filtration possible.
The molded grip and unique geometry ensure aseptic handling. The sterile strainer can be easily removed from the special blister packaging without touching its interior surface or mesh.
The advanced frame/housing design reduces processing time, by eliminating the air-lock effect. Improved aeration allows air to escape while filtrate is entering the tube, preventing messy spillovers. Simply open the sterile package, attach the strainer to the top of a 50 ml tube and add your cell suspension/sample. The provided reducing adapter is for use in 15 ml tubes. Sure Strain produces an optimized filtrate for maximum flow in separate columns and cytometers.

Cole-Parmer Replacement Pestle/Mixer Adapter for Motor, 1 each
Use the battery-operated motor mixer with pestles and microtubes to drastically reduce hand fatigue when mixing multiple samples. Cell tissue and pellets are completely homogenized within seconds by means of high-speed vortexing action. Order pestles and tubes separately. The replacement rubber adapter, model 44468-26, is the adapter only, and is only compatible with the 44468-25 pestle mixer. This adapter atteches the motorized mixer to the pestle connector.

Electron Microscopy Sciences Dounce Dura Grind Tissue Grinder, 15 ml, 35 mm x 114 mm Mortor, 171 mm OAL
Wheaton Dura-Grind Stainless Steel Dounce Tissue Grinder provides a rugged alternative to glass Dounce tissue grinders. Smooth pestle action requires less effort than glass tissue grinders. This unit is precision machined of No. 316 stainless steel to the tolerance of 0.0005 in. (0.013 mm). The mortar has flat bottom allowing it to stand upright. Single pestle and mortar are supplied as a matched set; they are NOT autoclavable. Weight 2 lb (0.9 kg)
Size: 15 ml
Mortor: 35 mm x 114 mm
OAL: 171 mm
Electron Microscopy Sciences Potter-Elvehjem Tissue Grinder, 15 ml, 19 mm x 94 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.
Size: 15 ml
Mortor: 19 mm x 94 mm
OAL: 219 mm
Electron Microscopy Sciences Dounce Tissue Grinder, 40 ml, 32 mmx 140 mm Mortor, 185 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: 40 ml
Mortor: 32 mmx 140 mm
OAL: 185 mm
