Prepare aspirating tubing 68 68 68 68 : Cut a piece of the 6.1803.020
PTFE tubing to the required length (normally ca. 120 cm).
x
Insert one end of the aspirating tubing 68 68 68 68 into the rinsing
solution storage bottle and tighten it so that the tubing is
firmly held.
x
Insert the free end of aspirating tubing 68 68 68 68 into one of the
openings
5555
of the 792 Basic IC ( see Fig. 2 ) and pull it suffi-
ciently far into the interior.
