Product Description
Titration endpoints are only as good as the buret that delivers them. These Class A glass burets give you a clear view of the liquid column and a smooth-turning stopcock, so you can add titrant drop by drop with confidence and get repeatable results run after run.
This listing is for catalog number 21310-50: Glass Buret, 50 mL. Each buret is made from borosilicate tubing with a low coefficient of expansion and carries large, permanent graduations that are easy to read. The PTFE stopcock needs no grease, avoiding sticking and lubricant contamination. They are calibrated to deliver and meet ASTM E287 Class A. Options include 10 mL, 25 mL and 50 mL capacities with fine graduation intervals. LIGHT LABS stocks the Heathrow Scientific line, so racks, replacement parts and consumables are easy to reorder.
