Push the O-ring (2) about 1 cm onto the wide side of the injector.

Grease the joint of the inner and outer tubes with the supplied oiled cloth
until it shines transparently.
}
Carefully push the inner tube into the glass body in the holder as far as it
will go. Lightly rotate the tube while doing so to avoid jamming and to
make sure that the ground glass joint is sealed.

The injector tip must be exactly flush with the outer edge of the inner
tube.
The injector tip must not protrude beyond the outer edge of the inner
tube. The tip can, however, be a maximum of 1 mm below the outer
edge.

If the injector tip could not be properly aligned:
– Remove the inner tube from the holder and loosen the screw connec-
tion of the connection piece.
– Push the injector into the holder as far as it will go. Slight resistance
from the O-ring seal must be overcome.
– Afterwards reinsert the inner tube and check the proper fit of the in-
jector.

Insert the outer tube in the glass body with a rotating motion. Ensure
that the ground joint seal is tight.
