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
list includes tubing diameters, flow rates in µL/min and the
maximum flow rates at 6 rpm and 60 rpm. Tubing is listed by
part number. For best results, when using two tubes, select
tubes that provide flow rates within a 10:1 range.
(Tube diameter ratios should be within approximately 3.5:1.)
Silicone tubing should not be used with TYGON
NORPRENE ® .

Installing Tubing in Pump Head

WARNING: Be sure the Pump Drive is turned off
before proceeding. Loose clothing
could be caught in the rollers.
1. Place the Power On/Direction Switch, Figure 2, in the
center (Off) position.
2. Press down on the Occlusion Bed Latch, Figure 4, to
release the Occlusion Bed from the rotor.
3. Gently stretch the tubing and insert the tubing into the
spring-loaded left rear Retainer.
4. While maintaining the slight amount of stretching, wrap the
selected tubing around the lower Rollers and secure the
tubing in the right rear spring-loaded Retainer. If a second
tubing is to be installed, secure the tubing in the same
manner using the front spring-loaded Retainers.
5. Lift up on the outer edge of the Occlusion Bed until it locks
in position holding the tubing against the bottom Rollers.
