Manual pipette 200 series

volumetric1-channel

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. Class AS conformity certified Conformity means compliance with the German Calibration Regulations (DIN 12600) and the relevant standards. By imprinting the conformity symbol ”DE-M” we confirm that the measuring device complies with these conditions. A batch certificate of conformity is supplied together with every box. On request individual certificates of conformity are available. 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 made of soda lime glass acc. to DIN EN ISO 648 (except 3 ml, 4 ml and 15 ml) especially formed tips and ends, bevelled and fire-polished calibrated tips provide short and practice-oriented waiting time with colour coding for easy identification with indication of tolerance with 1 circular mark
