This tissue grinder is designed to retain a high percentage of cell nuclei and mitochondria in soft tissues or from cell cultures. In operation, the pestle ball is encircled in liquid, which avoids heat buildup by reducing friction. This grinder is ideal for enzyme studies. 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 works best with cell suspensions or very soft tissue. The mortar has a large reservoir and pouring lip and is supplied with a "loose" pestle and a "tight" pestle. Two complete sets per case. Tight Pestle "A" Specification: 0.0010-0.0030 in (0.025 - 0.076 mm), Loose Pestle "B" Specification: 0.0035-0.0055 in (0.089 - 0.14 mm)
