SETUP
Use only Microbore Autoanalysis tubing with
MASTERFLEX C/L pumps to ensure optimum
performance. Use of other tubing may void
applicable warranties.
Selecting Tubing Size
Appendix A provides a list of tubing sizes which will work
efficiently with the MASTERFLEX C/L Pump System. This
list includes tubing diameters, flow rates in µL/min and the
maximum flow rates at 10 rpm, 80 rpm and 300 rpm. Tubing
is listed by part number.
Installing Tubing in Pump Head
WARNING: Before installing tubing into the Pump
Head remove power or shut off the drive.
Fingers or loose clothing could be
caught in the rollers.
1. When the door is opened the Occlusion Bed moves back
away from the pump rollers,
Figure 4
.
2. Holding both ends of the tubing in one hand, form a loop and
wrap the tubing around the
Rollers
,
Figure 4
, making sure
that the tubing is centered on the rollers and keeping the free
ends of the tubing outside of the
Tubing Retainers
,
Figure 4
.
3. Once the tubing is in place, close the Door and the
Occlusion Bed will automatically align itself within the pump,
Figure 5
.
4. Insert the tubing into one of the
Tubing Retainers
,
Figure 4
,
by moving the retainer toward the center of the pump and
placing the tubing in the v-notch of the retainer. Release the
retainer so that the tubing is secured in place. Repeat for the
other tubing retainer. The tubing should be stretched slightly
around the rollers so that there is no excess tubing between
the rollers and the retainers – any excess can be removed by
pulling slightly on the tubing outside of the pump.
