9.4 Tubing
Danger of injury from defective tubing.
The bath fluid tubing is a potential source of danger at high working
temperatures. Large volumes of hot bath fluids can be pumped out of
a damaged tubing in a short period of time.
Possible consequences:
• Skin burns
• Breathing problems due to the hot atmosphere
Danger from unsealed pump connections.
• If the pump connections are not sealed, bath fluid may be
pumped out without any control.
• Set the lever on the pump to internal circulation.
• Unused pump connections must always be sealed with sealing
screws.
Danger from the incorrect use of tubing.
• The tubing must be suitable for the pressure and temperature
range which results from operation and for the bath fluid (for
example silicon oil must not be used with silicon tubings).
• Secure the tubing connections to prevent them sliding off. Use
tube clamps.
• Do not kink the tubing. This will reduce throughput and may
cause the maximum pressure in the system to be exceeded (glass
reactor). The tube length should therefore be kept at a
reasonable level.
• Prepare a maintenance plan.
Check tubing at regular intervals, at least once per year, for signs
of material fatigue (for example cracking)
The tubing must be replaced at regular intervals if they are in
constant use.
We recommend that you select suitable tubing on the JULABO
homepage.
