VWR PTFE Tissue Grinders Plain Plungers. The tissue grinders ensure dry operation because no liquids can be trapped between the PTFE head and the glass vessel. The tissue grinders allow only small tissue pieces to pass through. PTFE is the color of the grind and cannot be seen or felt on the skin of the hand or plunger. PTFE is also inert and non-contaminating. This is important during the isolation of pathogens from clinical specimens.
