10 and 120 µl pipettes 300 and 1000 µl pipettes 5000 µl and 10 ml pipettes
Parts and materials:
1. Tip ejector collar (polyvinylidenefluoride (PVDF)) in 10 µl, 120 µl, 300 µl and 1000 µl pipettes, (polypropylene (PP)) in 5000µl and
10ml pipettes.
2. Locking ring (polyetherimide (PEI) in 10 ml pipettes, polyamide (PA) in all other pipettes)
3. Tip cone (polyvinylidenefluoride (PVDF) in 10 µl pipettes, polyetherimide (PEI) in 200 and 300 µl pipettes, polyphenylenesulphide
(PPS) in 1000 µl, 5000 µl, and 10 ml pipettes)
4. Piston (stainless steel (SS) in 10µl pipettes, polyphenylenesulphide (PPS) in 120 µl, 5000 µl and 10 ml pipettes, polyetherimide (PEI)
in 300 µl and 1000 µl pipettes)
5. Piston seal (fluoroelastomer (FKM) in 10 µl and 10 ml pipettes, ethylene propylene diene monomer (EPDM) in 120 µl, 300 µl,
1000 µl and 5000 µl pipettes)
6. Spring (stainless steel (SS) in 10 µl, 120 µl, 300 µl and 1000 µl pipettes)
To clean and decontaminate the lower parts of a single-channel pipette, follow the steps below:
To disassemble and clean the pipette:
1. Remove the tip cone filter using the tweezers provided.
2. Unscrew the tip ejector collar (1) counterclockwise and remove it.
3. Depending on the pipette volume:
a. With all pipettes other than the 5000 µl or 10 ml models, unscrew the locking ring (2) counter clockwise and carefully remove
it together with the tip cone (3).
OR
b. With a 5000 µl pipette, hold the locking ring (2) firmly with your fingers and turn the tip cone cylinder counter clockwise with
the other hand (see image below). Do not turn the locking ring as you turn the tip cone (3) as this will break the pipette.
