Automatic burettes acc. to Pellet

Automatic burettes acc. to Pellet

Burettes are calibrated volumetric instruments with graduations and ground-in stopcocks. They are used in laboratories for quantitative measurements of smaller liquid volumes in titration.

Burettes are calibrated ”Ex” (to deliver): The imprinted volume corresponds to the delivered quantity of liquid.

A Schellbach stripe (optional) facilitates reading precisely the meniscus of a liquid.
 
  • Class AS (fast delivery)
    ”A” stands for highest accuracy, ”S” for fast delivery.
    The tolerances of class AS are half of the tolerances of class B according to DIN ISO standards.
