The Pipette Controller is normally maintenance-free. When
necessary, the housing can be wiped occasionally using a damp
cloth.
Cleaning the Pipette Adapter and Replacing the Filter
If liquid has entered the nozzle or if the aspirating efficiency has
decreased, observe the following instructions:
1. Hold the pipette over a container and remove the pipette.
2. Gently unscrew the nozzle.
3. Remove the filter.
4. Remove the pipette adapter from the nose cone by pushing it
upwards.
5. Rinse the pipette adapter with demineralized water and allow to
dry at room temperature.
6. The filter’s smooth sided connector must be facing the pipette
adapter. The filter’s stepped, larger diameter connector should be
facing the filter adapter. Push the filter adapter onto the filter.
7. Reassemble the instrument by reversing the steps above.
8. Test instrument for leaks, see “Checking for Leaks” (below).
Notes
— Not all membrane filters are suitable for use with the instrument.
For proper performance, only use the manufacturer’s
recommended replacement filters.
— The pipette adapter, nozzle, and filter adapter may be steam
sterilized at 121°C for 20 minutes.
—It is the user’s responsibility to ensure proper sterilization.
Checking for Leaks
When the pipette has been filled, liquid should not drip from the
pipette. Should the pipette drip, disassemble the pipette adapter,
filter, and filter adapter. Carefully reassemble. If necessary, replace
worn parts. See “Ordering Information”.
Maintenance
Caution!
When cleaning and exchanging the filter, wear protective gloves
and safety goggles to avoid the risk of splashes and
contamination.
