Pyrex Borosilicate Glass Tissue Grinder with Glass Pestle - 1ml Capacity - Lab Homogenizer for Cell Disruption & Sample Preparation - Ideal for Biology, Chemistry & Research Labs

These 1mL PYREX tissue grinders are designed to handle both initial grinding and final homogenization in the same sequence of operations. The lower conical section is intended primarily for the initial grinding. To assist in this work the clearance between mortar and pestle can be adjusted at will by raising or lowering the pestle. The upper cylindrical section is for the final homogenization.
