Borosilicate glass tube, PTFE pestle with stainless steel shaft. Tissue grinders are used for controlled reduction of particle size and homogenisation of a variety of substances, especially biological material. The shearing forces generated by the movement of the rotating plunger in a precision bore tube cause size reduction, determining factors include clearance between the pestle head and tube, speed of rotation and viscosity of medium.

Grinding chamber clearance: 0,15 to 0,25 mm.

Diameter of stainless steel shaft: 6,5 mm.
