Burettes are calibrated volumetric instruments with graduations and drain cocks.
They are used in chemical laboratories for quantitative measurements of small volumes of liquids in titrations.
The burettes are "Ex" calibrated: the printed volume corresponds to the quantity of liquid dispensed.
Class AS "A" stands for maximum precision, "S" for fast delivery.
The tolerances of class AS are half of the tolerances of class B according to DIN ISO standards.
