8. Grease the cleaned parts with the lubricant recommended by the manufacturer.
9. Reassemble the pipette components.
All 0.2-50 µl: First, slide the spring 14, spring support 15 and tube 16 back on the piston.
Compress the spring with fingers by pressing piston and spring support 15 agains eachother.
5-50 µl: Slide bigger O-ring 17, smaller O-ring 18, (2-20µl bigger O-ring 18a, smaller O-ring
18b), spring support 19 (sharp edges against spring) and small spring 20 on the piston.
0.5-10 µl: First slide O-ring tube 17 (larger hole first), bigger O-ring 18, smaller O-ring 19
and O-ring support 20 on the piston. Then slide small spring 21, spring support 22
(sharp edges against spring) and O-ring 22 on the O-ring support 20.
0.2-2 µl: First slide O-ring tube 17 (larger hole first) and sealing combination 18 on the
piston. Then slide small spring 19, spring support 20 (sharp edges against spring) and O-ring
21 on the sealing combination 18.
All 0.2-50 µl: Carefully slide the entire assembly into the tip cone and release your fingers.
10. With the push button depressed all the way carefully attach the tip cone to the handle
so that the adapter opening is on the tip ejector side. Do not bend the thin piston wire when
assembling. Press in the snap joints.
11. Assemble the tip ejector and check the calibration according to the instructions.
DISASSEMBLING 50-1000 µl PIPETTES
1. Press the tip ejector.
2. Insert the pliers under the ejector bar to release the tip ejector.
3. Remove the tip cone using the maintenance pliers.
4. Pull out the piston.
5. Remove the O-ring, O-ring support and spring from the tip cone.
6. Clean the piston, the piston spring and the O-ring with a dry napless cloth.
7. Check the cylinder for foreign particles.
8. Grease the cleaned parts with the lubricant recommended by the manufacturer.
9. Slide parts over the piston pressing down the large spring. Attach the tip cone to the handle
so that the adapter opening is on the tip ejector side, and press in the snap joints.
10. Check the calibration according to the instructions.
DISASSEMBLING 1-10 ml PIPETTES
1. Press the tip ejector.
2. Insert the pliers under the ejector bar to release
the tip ejector.
3. Remove the part 2 from part 1 of the tip ejector
using the maintenance pliers to release the
snap joint.
4. Remove the cylinder by pressing part 1 of the tip
ejector firmly towards the cylinder. This action
releases the snap joint so you can remove
the cylinder.
5. Clean the O-ring and cylinder. Regrease the
O-ring ang the cylinder.
6. Assemble the parts in the opposite order of
disassembly. All joints are snap fit and can be
pushed together by hand. Be careful not to bend the pipette during assembly because this
could damage the snap joints or the piston.
7. Check the calibration according to the instructions.
