c. With a 10 ml pipette hold the tip cone cylinder firmly and turn the locking ring (2) clockwise with your fingers (see image
below). Do not turn the tip cone (3) as this will break the pipette.
4. Clean the tip ejector collar (1), the tip cone holder, the tip cone cylinder, and the piston (4) with a disinfectant liquid or mild
detergent and a soft, lint-free cloth.
5. Clean the interior of the tip ejector collar (1) and the tip cone cylinder with a cotton swab. Be careful with 3, 10, 20, and 100 µl
pipettes to ensure the seal inside the tip cone is not damaged.
6. Rinse the parts with distilled water if necessary and allow them to dry.
7. Depending on the pipette volume:
a. With a 10 µl or 120 µl pipette, apply a thin layer of grease on the piston (4).
OR
b. With a 300 or 1000 µl pipette, apply a thin layer of grease around the seal (5).
OR
c. With a 5000 µl or10 ml pipette, apply a thin layer of grease on the interior of the tip cone cylinder and around the seal (5).
NOTE: Avoid excess grease. Only use the grease provided with the pipette.
NOTE:
Before reassembly, check that there is no lint or particles on the surface of the piston.
NOTE! Always check the performance of the pipette after cleaning or maintenance.
To reassemble the pipette:
1. Depending on the pipette volume:
a. With a 10, 120, 300, or 1000 µl pipette, carefully place the tip cone (3) on the piston (4) and attach it by screwing the tip cone
holder clockwise.
OR
b. With a 5000 µl pipette, carefully place the tip cone cylinder on the piston (4) and screw clockwise. Make sure the tip cone
cylinder is properly tightened. Avoid over-tightening.
OR
c. With a 10 ml pipette, carefully place the tip cone cylinder on the piston (4) and screw the locking ring (2) counterclockwise.
Make sure the tip cone cylinder is properly tightened. Avoid over-tightening.
2. Attach the tip ejector collar (1) by screwing it clockwise.
3. Insert a new tip cone filter.
4. Press the operating button several times to ensure that the grease has spread evenly.
