Graduated pipettes, glass

Pipettes with capacity graduation are used to dispense liquids. They are calibrated ”Ex” (to deliver): the imprinted volume refers to the delivered amount of liquid. Graduated pipettes for complete delivery are called serological pipettes. 

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 ”H” 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.

Amber graduation: the amber stain graduation penetrates into the glass surface and is, therefore, 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".
