The needle-valve stopcock

PTFE valve spindle
Operates smoothly and is yet tight, even without lubrication, so there are no grease residues on the burette. The valve spindle is replaceable.

Tight seal without force
A gentle turn is all it takes to close the burette valve.

Precision burette tip

   Precise drop by drop control. Drop size remains
   constant - from the first to the last drop.
   The liquid stream breaks off precisely and
   does not creep along the outside edge.
