Graduated pipettes, glass

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.
    Conformity symbol
    By imprinting the conformity symbol "DE-M" along with the year 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".
