3.2 Dosing unit – Function
Software controls can be used for accurate dosing of liquid volumes with
the dosing unit.
The dosing unit is comprised of the following units:
￭The dosing drive
￭The cylinder unit
The dosing drive is permanently installed in the housing of the instrument.
It is controlled via the OMNIS Software and is responsible for the accurate
dosing of the solution.
If the cylinder unit is placed on top of the dosing drive, the dosing drive
assumes responsibility for the following functions:
￭Raising and lowering the piston:
Solution is aspirated if the piston is lowered. The cylinder fills up.
Solution is dosed if the piston is raised. The cylinder empties.

￭￭￭￭￭￭￭￭ 13
￭Rotating the cylinder:
The rotation of the cylinder controls which of the four ports the solu-
tion flows through.
The valve disk with an opening is located in the middle of the cylinder
base.
The distributor disk with four openings corresponding to the four ports
of the distributor is located at the bottom in the cylinder attachment.
The dosing drive rotates the cylinder by 90° stages so that the opening
of the valve disk fits with an opening on the distributor disk. This
results in a passage for the solution to the corresponding port of the
distributor.
3.2.1 Cylinder unit – Function
The cylinder unit is an accessory set for the dosing unit in OMNIS instru-
ments with dosing function.
The movements of the piston and the cylinder are controlled via the
OMNIS Software.
An antidiffusion tip (6.1543.200) is part of the accessories of every cylin-
der unit. The antidiffusion tip is used whenever the titration tip is
immersed into the sample. The antidiffusion valve prevents the sample
from diffusing into the tip.
If accurate dosing is important, then you can order a dosing tip
(6.1543.100) as an alternative to the antidiffusion tip. The dosing tip must
not immerse into the sample.
