5.2 Inserting the pipette
5.3 Pipette types
Measuring pipettes and volumetric pipettes are divided into 3 classes: A, AS and B. Class
A and AS pipettes are more precise than Class B pipettes. They vary according to the
elapse time. The elapse time depends on the nominal volume and the design of the
pipette. Class AS pipettes are quick-drain pipettes.
Volumetric pipettes have 1 or 2 marks and are adjusted to flow-out. Measuring pipettes
have a scale and are divided into 4 types.
WARNING! Risk of cuts from shattered glass pipettes.
Glass pipettes are fragile and may cause severe cuts if they break.

Do not insert the glass pipettes using force.

Wear your personal protective equipment (PPE).

Use a towel to protect the hand used for insertion.

Pick up the pipette from above and
carefully insert it in the aspirating cone
until is positioned securely and air-tight. Abb. 5-2:Inserting the pipette

Eppendorf Serological Pipets are pipettes that are calibrated to flow-out. The
zero line is located at the upper end of the graduation. Dispensing can be carried
out to any scale graduation on the scale or until the pipette is completely empty.
