Burettes are calibrated volumetric instruments with graduations and groundin 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, circular graduation at main points). ”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.
