For the following dispensing tasks it can 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 bended during dispensing.

Eppendorf pipette tip cone.
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. Slightly
squeeze the clamps on the lower part when doing so.

part.
4. Fit the ejector sleeve onto the ejector rod. It is fitted correctly if it
engages slightly.
Remove the locking ring to reactivate the spring-loading action.
