All of the attached modules in the OMNIS Sample Robot System are sup-
plied with electricity through the main module Pick&Place.
The main lift with gripper and gripper arm is fastened to the main module
Pick&Place.
The gripper is used for transporting the sample beakers out of the sample
racks and into the processing stations intended for this purpose. Once the
processing of the samples has been completed, the gripper removes the
sample beakers out of the processing stations once again and transports
them back into the previously removed sample rack.
The control hardware is integrated in the interior of the main module
Pick&Place.
The samples in the OMNIS sample robot system are analyzed on the
Pick&Place module.
The sample beakers are transported by the sample robot into the front
sample position of the Pick&Place module. After the sample beaker has
been put into place, the slide with the sample beaker moves under the
titration head and the lift moves downward.
The sensors installed in the titration head analyze the sample.
After completion of the measurement, the sensors are cleaned with one
of the pumps that are integrated in the pump module. The solution that is
generated during this process is aspirated by an additional pump of the
pump module and the lift with the sensors rises.
Afterwards the slide moves back out again and the sample beaker is
removed by the sample robot.
2 or 4 peristaltic pumps are integrated on the peristaltic pump module.
2 peristaltic pumps are assigned to each workstation in the OMNIS sample
robot system.
The upper peristaltic pump (numbered with 1 or 3) rinses off the sensors
in the Pick&Place modules with solvent after the analysis of a sample. For
this purpose, the solvent is aspirated from the rinsing canister through the
peristaltic pump. If required, these pumps can also be used to dilute a
sample with solvent or to bring it into solution prior to an analysis.
The lower peristaltic pump (numbered with 2 or 4) aspirates the remaining
solution out of the sample beaker during and after the rinsing procedure
and routes it to the waste canister.
