Feed the sample line through the rubber grommet in the middle of the
wash pump tubing ducting and then slot the sample line into the tube
anchor clip between the colored markers on the tubing as shown in
Figure 14 . The tube markers on the sample line define the optimal
sample length of sample line from the sample probe to the exit point of
the autosampler.
The following lists the color of the tube markers on the sample probe
tubes.
• Red: Sample probe kit, 0.25 mm ID
• Yellow: Sample probe kit, 0.5 mm ID
•
Green: Sample probe kit, 0.8 mm ID
• Blue: Sample probe kit, 1.0 mm ID
• Black: Sample probe kit, 1.2 mm ID
•
Red: Sample probe to suit microtiter plate

Connect the sample line to the input of your instrument's sample
introduction system, adjusting the length from the exit point as
required.
Fitting the Wash Pump Tubing
A wash pump is fitted on the rear of the autosampler and is used to
supply fresh rinse solution to the fixed wash reservoir. The wash pump is
a three channel peristaltic pump with four rollers and an individual
pressure plate for each channel. One and two channels of the wash pump
are used to feed rinse solution into the single and dual port fixed wash
reservoirs respectively. The third channel can also be used to pump the
used rinse solution to the waste container (optional).
The wash pump is controlled by the instrument control software and
rotates clockwise.

It is important to ensure that the length of the tubing allows the probe arm to move
freely in all axes. If it is too tight, it will restrict the probe arm and may cause a
movement failure. If it is too loose, the probe arm may become tangled in the tubing as
it moves.
