Pipettes with a scale are used to dispense liquids. They 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 seconds). 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 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 in every packing unit. On request, individual certificates of conformity are available. - Graduation
The amber stain graduation 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 835 (except capacity 0.1 ml)
- low risk of breakage
- 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
- as from 5 ml capacity with constricted upper end to retain cotton plug. A cotton plug prevents an overflow of the pipette. But it can also extend the waiting time and thereby influence the accuracy of the measuring.
- circular graduation at main points, well legible numbers and graduations
- for complete delivery, zero at top
Do not mouth pipette! For recommended pipetting aids please see "Pipetting aids and accessories".
