8.7. Assembling the vessel lid, stirrer guide and probe
8.7.1
Before attaching the lid to the reaction vessel the stirrer assembly must be mounted
in the lid.
8.7.2
Position the Stirrer Guide in the central B24 lid port. Hand tighten the central red
(Rodaviss) screw cap to secure.
8.7.3
Loosen the metal cap on the Stirrer Guide, then slide the stirrer shaft through the Stirrer
Guide from below, until the top of the stirrer shaft is sitting just above the top of the metal cap.
8.7.4
Hand tighten the metal cap to lock the stirrer shaft in place.
8.7.5
Locate the lid on the vessel by guiding the stirrer shaft through
the neck of the vessel and position it over the upper lugs of the o-ring
collar sitting on the vessel flange. Ensure that the vessel o-ring and
lid are all sitting flush.
8.7.6
Close the jaws of the vessel clamp so that they locate around the flange of the vessel
and lid. Hook the bolt of the fastening clip into the retaining recess on the clamp and snap the
clip shut. This clamps and seals the vessel and lid. Visual inspection of the o-ring through the
opening at the front of the clamp should indicate a witness line where it contacts the lid flange.
8.7.7
Adjustment of the clamp is possible by screwing the bolt of the fastening clip in or out
to tighten or loosen the grip. This is best achieved with the vessel clamp in the ‘open’ position.
8.7.8
Screw the PTFE temperature probe adapter into the the B19 joint/port, slide in the
PTFE probe to the required position. The PTFE probe can be bent slightly to ensure it does
not foul with the PTFE stirring blade. Tighten the light blue
cap to lock the probe in position.
8.7.9
The Pt100 probe is supplied with a Lemo connector
for connection to the thermoregulator.
8.7.9
Add any additional accessories (dropping funnels,
solids addition funnels etc to the lid ports and secure by
hand tightening the red (Rodaviss) screw cap fittings.
8. Set-Up & Operation
- Continued
Important Note -
When clamping the vessel and lid together there should
be minimal movement of the vessel or lid. If significant movement, either side-
ways or vertical, is observed it is likely that the vessel support collar is incor-
rectly positioned on the vessel neck. Remove the vessel from the clamp and
reposition the collar on the vessel (see 8.6.2).

The glass lid is supplied with
four (Rodaviss) red sealing caps that are used to
blank off the joints when not in use. The sealing caps
have PTFE face inners for an inert seal.
