For homogenizing delicate tissues such as intestines, liver, and heart

Interchangeable pestles and tubes are made of Wheaton 33® low extractable borosilicate glass. Clearance between pestle and grinding chamber is 0.09–0.16mm (0.0035–0.0065"). Glass meets ASTM Type 1 Class A and USP Type 1 standards.

Designed for hand operation, grinders can also be slow-speed motor driven by inserting a rubber stopper (size 00) and metal rod into the pestle. Hollow handle permits packing with ice. Grinders also feature an expanded reservoir and pouring lip.
