Description

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.

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.

Features and Benefits:

• 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, beveled and fire-polished
• Calibrated tips provide short and practice-oriented waiting time
• 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
• Tolerances: 50 : ± 0.006 ml, ± 0.006 ml, ± 0.007ml, ± 0.010 ml, ± 0.010 ml, ± 0.030 ml, ± 0.050 ml, ± 0.10 ml, ± 0.10 ml, ± 0.20 ml
• Class AS conformity certified options as well on request
