Burette, Automatic Zero, Amber Glass, Class A

Medilab Automatic Zero Burette is mounted on an Amber Glass Reservoir with a straight bore PTFE key stopcock & Rubber Bellow. Class ‘A’.

Amber Glass is used when working with Light-Sensitive Chemicals.

• With Batch Certificate
• Complies with DIN/ISO 385 standard

An automatic burette is connected with a bottle containing the titration solution. The rubber bellow pumps the air into the bottle, creating pressure inside the bottle further which rises the solution to the top of the burette. As soon as the burette is full, the valve is released, which makes the pressure fall in the bottle and simultaneously the burette automatically sets itself to zero.
