PYREX® Glass Pestle Tissue Grinders

PYREX® glass pestle tissue grinders are designed to handle both initial grinding and final homogenization in the same sequence of operations. The lower conical section of these tissue grinders 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 of the tissue grinder is for the final homogenization.
