2.4.1 ETFE cylinder
• Insert the dosing piston into the cylinder as de-
scribed in the previous section.
• The centering tube for the plastic cylinder has a
recess on its lower surface.
•
Place the centering tube on the lower part of the
cylinder so that the recess encloses the double
rib on the outside of the lower part.
• Just as for the dosing unit with glass cylinder,
care must be taken that the marking ribs on the
distributor coincide with those on the outside of
the cylinder when placing the complete plastic
part on the distributor.
• The housing can now be attached in the same
way as described for the dosing unit with glass
cylinder.
⇐ Exception:
The 50 mL ETFE cylinder is similar in construction
to the glass cylinders and is assembled similarly.
