Volumetric pipettes are used to dose liquids. Only one circular mark showing the defined volume is printed on volumetric pipettes. Volumetric pipettes are calibrated ”Ex” (to deliver): The imprinted volume refers to the delivered amount of liquid.
Classification:
Class AS
”A” stands for highest accuracy, ”S” for fast delivery (waiting time reduced to 5 secons). The tolerances of class AS are half of the tolerances of class B according to DIN ISO standards.
Graduation:
The amber stain graduation of our volumetric pipettes penetrates into the glass surface and is more resistant than a blue, fused-on enamel graduation
