2.4 858 Professional Sample Processor
For a detailed description, please refer to the 858
Professional Sample Processor manual. In general, you will
have to do the following: Plug in the Swing Head connection
cable, and plug in the power supply cable. The sample
processor initializes and lifts its Swing Head, once it is
connected to the IC device and the MSB connection is
recognized. Afterwards, it is possible to mount the retaining
plate (manual chapters 3.2 - 3.4).
Mount the Dosino holder (6.2057.040) on the side of the
tower and attach a 10 mL Dosing Unit (6.3032.210) and a
800 Dosino (2.800.0010) to it.
A rinsing station is mandatory for this setup.
The rinsing station is mounted onto the sample processor,
which is easiest when the rack is temporarily removed. The
exact position can be adjusted by directing the needle into
the rinsing station with the manual control (in the window
manual). The inner compartment approximately relates to a
swing head angle of ~116°, the outer one approximately
relates to ~110°. Memorize your angle settings.
Fig.: Rinsing station parts
A tubing is fixed at the bottom of the rinsing station to drain
the waste water. A bottle of ultrapure water is needed as
reservoir for the rinsing solution. The rinsing solution is
transported by one channel of the peristaltic pump of the
sample processor.
Mount the rinsing station on the sample processor.
Connect ultrapure water reservoir with the peristaltic pump
(via pump tubing (6.1826.360) and PEEK screws / tubing
olives) using a PTFE capillary (part of 6.1803.030). Then
connect the peristaltic pump (via pump tubing and PEEK
Screws / tubing olives) to the inner compartment of the
rinsing station also using a PTFE capillary (part of
6.1803.030).
The outer compartment of the rinsing station is connected to
the waste container.
