The tubing is compressed into the valve by the ferrule to ensure that the connection is
leak-tight. When making tubing connections:
1. Slide the nut over the tubing.
2. Slide the ferrule over the tubing, with the narrow end towards the end that will be
connected to the valve. Push the tubing through the ferrule until 3-4 mm of the
tubing projects from the narrow end of the ferrule.
3. Insert the end of the tubing in the valve connection until it touches the back of
the connection.
4. Hold the tubing in this position and screw the nut into the connection on the
valve.
5. Fasten the nut finger-tight.
Replacing cell transport fluid tube
As part of your regular maintenance routine, or whenever you suspect that the tubing
may have become blocked, this can be replaced as follows:

Undo the retaining connector from the top tube, where it connects to the right
side of the valve at the top of the syringe. Remove the tube. Replacement is a
reversal of the removal process.
Note: ensure that only parts supplied by Malvern Instruments are used.
