50mL Automatic Burette, Class A

by United Scientific

   This 50mL burette is automatic and self-zeroing. It features two PTFE stopcocks, one being a screw type (rotoflo) controls flow out of the buret itself, and the other is a traditional stockcock which allows any excess liquids to be drained from the buret and back into the reservoir. The burette features a ground glass ring where it connects to the top of a 2000mL glass reservoir with matching ground glass neck. The glass tubing of the buret sits down inside the reservoir near the bottom. A silicone bellows with rubber tubing connects to the buret near the bottle neck to make filling easier and more precise. Above the top of the buret, a small, open-air reservoir is present to allow airflow into the buret and prevent air bubbles from forming in the tube.

Each burette is made from Class A glass, is individually calibrated, and comes with a calibration certificate.
