Replacing Parts
Replacing Tubing
It is important to keep all tubing clean and free of
crimps. Tubing that has become dirty, blocked, or
crimped can result in poor accuracy and precision.
Replacing Parts
Replace tubing as needed. See Appendix A for part
numbers for replacement tubing.
To replace the calibrated tubing:
1 Disconnect the calibrated tubing from the
injection port. To fully remove the fitting, do the
following:
a) Loosen the two knurled screws that secure
the injection module to the liquid handler.
See diagram on page 2-2 if necessary.
b) Lift and tilt the injection port plate from the
top of the injection module with one hand
while loosening the fitting with the other
hand.
2 Disconnect the calibrated tubing from the
injection valve.
