The instrument will then perform the power on self-test protocol. The power on and self-test screen
will be shown:
If the module has been successfully installed the instrument will show ‘Passed’ alongside the
Accessory test… indicator.
If the module is incorrectly fitted to the instrument the message ‘none Found’ will be displayed. If
this occurs switch the instrument off and disconnect from the mains supply. Remove the module and
carefully refit. Reconnect the instrument to the mains supply and switch on. If the fault remains please
contact your local dealer for advice.
Fitting the Sipper Pump tubing
The Tubing Kit supplied with this module contains:
Sipper Pump Tubing (1 metre) – 023 029
Capillary Tubing (0.5 metre) – 023 030
Sipper Probe – 632 063
In addition a 2.5mm Sample Mask (035 242) for use with micro cell, is supplied with the accessory
module.
For traditional sipping:
note: It is recommended that all tubing runs are kept as short as possible. Tubes must not be allowed
to obstruct the light path.
For 1.8 ml flow through cells ensure that the sample flows into the smallest chamber i.e. the cell fills
from the bottom up. For 80µl flow through cells the direction of the flow is shown on the cell.
1. Connect the sipper pump tubing (023 029) to the outlet port on the flow-through cuvette.
2. Secure the tubing using the clip on the right hand side of the pump head.
3. Ease the tubing around the rollers by carefully rotating them clockwise, by hand. Clamp the tubing
into the clip on the left hand side of the motor.
4. Once secured, ensure the tubing is routed into the two retaining clips located on the module base
plate at the side of the pump head.
5. Cut the tubing at the point where it fits comfortably on to the left hand tube located on the inside
of the front bulkhead.
6. Connect a suitable length of this tubing to the external waste pipe.
7. Cut a small length (approx. 10mm) of the sipper pump tube (023 029) and push this over one end
of the capillary tube (023 030). Connect this to the inlet port of the flow-through cuvette.
8. Route the tube into the two retaining clips located on the module base plate at the side of the
pump head.
9. Fit the sipper probe (632 063) and secure using the thumbscrew. Feed the capillary tubing through
the tube and up through the sipper probe, allowing sufficient length for it to pass into a suitable
receptacle.
