Eppendorf Xplorer® (plus) — Operating manual
7.4.3 Multi-channel
Loosen and open the 10 μL, 100 μL and 300 μL multi-channel lower part
1. and : Slide the lever on the lower part to the left or right. Pull the lower part down to cancel
the magnetic coupling of the lower part to the upper part.
This separates the lower part from the upper part so that it can be removed.
2. Put down the lower part with the lever facing downwards.
3.
: Slide the two latches (right and left at the side) down using a coin.
The lower part is still lying on the table with the lever facing downwards.
4. Remove the cover panel facing upwards with the integrated ejector rail.
Do not remove the ejector rail from the cover panel. The spring for the ejector rail may
accidentally come off and get lost in this step.
Removing and installing channels
Channels must only be removed and installed if the multi-channel lower part is separated from
the upper part! The channels in the lower parts consist of piston, cylinder and spring. The
channels for 100 μL and 300 μL are equipped with an O-ring at the tip cone (see Replacing
O-rings on p. 52).
1. and : Position a pipette tip under the piston and carefully take the piston off the upper rail.
2. Carefully pull the piston out in an upward direction. Do not bend the piston.
3. Hold the tip cone at the lower end and push it upwards slightly .
This compresses the spring.
4. : Lift the tip cone slightly and release it from the lower rail.
5. : Relax the spring by letting the tip cone slide back again above the lower rail.
6. Remove the tip cone, along with the cylinder and spring, from the upper rail.
Before installation, slide the piston into the cylinder. Install the channels in reverse order.
