Interchangeable PTFE valve spindle, PP cap and retention device. Valve opening 0-25.5 mm.

Please note: PTFE valve spindle operates smoothly yet is tight, even without lubrication, so there is no grease residue on the burette. The valve spindle is replaceable. Tight seal without force, a gentle turn is all it takes to close the burette valve.
