Attention!
When cleaning and/or exchanging the
membrane filter (5), wear hand and eye
protection to avoid the risk of splashes
and contamination. Remaining liquid can
run out.
9. Replacing the membrane filter/
Cleaning the adapter
If liquid has entered the adapter (6) or rather
the membranfilter (5) or if the aspirating ef-
ficiency has decreased, proceed as follows:
1. Hold the instrument over a suitable
vessel to allow all liquid to drain from the
pipette.
2. Grip the pipet as near the top as possible
and carefully pull it out while turning.
3. Unscrew the adapter support (7).
4. Pull out the membrane filter (5).
5. Remove the adapter from the adapter
support (7) by pushing it upwards.
6. To clean adapter (6), carefully rinse it by
using an appropriate compatible solvent
(e.g., water) in a wash bottle.
Blow out the liquid and allow to dry
completely.
7. Place the new membrane filter (5) with
the thicker end facing downwards into
the adapter (6) (with the smaller conical
side up).
