10.2 Mounting the Glass Flow Tube
Note: Use lint free gloves to keep the glass flow tube clean.
Important: Be aware that the glass flow tube is made out of thin walled glass and is very
fragile! Avoid scratches or dirt on the surface or inside the glass flow tube!
Follow these instructions to safely mount the glass flow tube on the tube holder:
• Insert an O-ring 5x1 over the tube holder rod. Insert another O-ring 5x1 over the glass flow
tube.
• Insert the glass flow tube in the flow tube protector. Squeeze it gently until you feel some
friction and push the glass flow tube with a slight turn over the two O-rings of the tube
holder rod. Push the tube with the tool to the far end. Avoid bending the rod of the tube
holder, as the tube may break. Release the pressure on the flow tube protector and
remove it from the glass flow tube.
• Push the twist cap to the far end of the tube. At this moment the markers on the twist cap
and the tube holder must be in the opposite direction (180°).
• Lock the twist cap by turning it 90°.
Note: Now the position of the markers on the twist cap and the tube holder must match (0°).
Only then will the glass flow tube be locked securely.
• Mount the tube protector so that it protects the glass flow tube.
