Deactivating spring loading
For the following dispensing tasks, it may be helpful to deactivate the spring loading action of the
tip cone.
• A pipette tip is to be used for a long period.
• The pipette tip is slightly bent during dispensing.
Deactivating this action may also be helpful for pipette tips that are not designed for the
Eppendorf pipette tip cone.
Single-channel pipettes
Multi-channel pipettes
The spring loading of the tip cones can be deactivated in the 10 μL, 100 μL and 300 μL
multi-channel lower parts by installing 2-3 locking clips. The locking clips are part of the delivery
package.
Requirement
• Multi-channel lower part is open and has been removed from the upper part (see p. 57)
• Channels removed (see p. 57)
1. Remove the spring from the channels.
2. Insert the channels without the springs.
3. Firmly press the locking clips onto the channels.
4. Assemble the pipette (see p. 58).
The spring loading action of the tip cone can be deactivated by installing the locking ring. The
locking ring is included in the delivery package.
1. Push the black locking ring onto the lower part from the top by slightly squeezing the
clamps on the lower part.
2. Insert the lower part into the upper part until it audibly engages.
3. Keep the ejector pressed. The ejector rod protrudes from the upper part.
4. Fit the ejector sleeve onto the ejector rod. If correctly fitted, it will engage slightly.
Remove the locking ring to reactivate the spring loading action.
