Radleys Reactor-Ready Lab Reactor - Disconnecting the Thermoregulator

40
Important information
→ Ensure that the thermoregulator has sufficient capacity to collect the full volume of thermofluid.
→ To achieve full drainage of the vessel, the thermoregulator needs to be at a lower height than the
lower sidearm of the reaction vessel. Ideally the thermoregulator should be positioned below the
Reactor-Ready assembly. If this is not possible, it may be necessary to raise the vessel support
clamp on the frame until the vessel is higher than the thermoregulator. Alternatively the vessel
can be drained to an external reservoir (see Step 3).
Step 3
To drain the thermofluid to an external reservoir, place a suitable container (with sufficient capacity to
collect the full volume of thermofluid) directly under the drain valve on the lower supply manifold.
Open the drain valve on the lower supply manifold. Then open the vent valve on the upper return
manifold. Allow the thermofluid to drain from the vessel jacket.
Close the drain valve and vent valve once the jacket is empty.
Useful notes
❖ The speed at which the thermofluid will drain is dependent on the height of the manifolds
relative to the vessel, and the exact positioning of the thermoregulator and hoses. Best results
will be achieved with the manifold as high as possible and the thermoregulator as low as possible.
6.4.9 Disconnecting the thermoregulator
Step 1
Once the thermofluid has been drained from the
vessel, the quick-release insulated hoses can be
detached from the vessel sidearms.
To do this, first unscrew the red Rodaviss screw
cap, and then gently ease the hose couplings from
the vessel sidearms.
