50 ml Burette, Glass Bead Stopcock

PLEASE NOTE: Due to supply issues, this product may be temporarily replaced with a 50 mL burette with a pinch-clamp stopcock. 

This economical glass burette, with 0.1 ml divisions, regulates fluid flow with a glass-bead stopcock. Burettes are used to accurately measure out chemical solutions.

Note: To regulate fluid flow with this glass bead stopcock, squeeze the rubber tubing right on the bead while pushing it a little to one side, thus creating a gap along the side of the bead for liquid to pass through.

Replacement rubber tubing can be found here. To replace the tubing, first remove the old tube (take if off of the burette, remove the glass ball, take off of the glass tip) then put the put the glass ball inside the new tube and attach both ends to the tube.

NOTE: Actual product may vary from the one pictured due to differences in suppliers.
