Replacing a Nozzle Filter
on Ovation QS Models
5. Pick up a new nozzle filter with tweezers and
place it into the tip end (non-threaded) of the
nozzle. The end of the filter with the visible
ridge should be inserted first.
6. Use the filter insertion tool to push the filter into
position. Firmly press down until the filter is
pushed to the bottom of the nozzle.
7. Tap the nozzle on the counter to remove any
loose cellulose material.
8. Re-insert the rubber nozzle plug into the front
end of the nozzle. The end of the plug without
side ridges is inserted first. Press in until plug
is even with surface edge of the nozzle. If filter
is not completely seated, the plug will extend
beyond the end of the nozzle. Remove plug
and firmly seat filter with insertion tool.
9. Place rubber tubing onto the nozzle, and screw
the nozzle onto the pipette in a clockwise
direction. Firmly tighten and remove tubing
from nozzle. Re-install ejector sleeve.
