8.7. Place Assembled Capped Tube in Carousel
Place the capped tube into the assembled Carousel at the required location, push the Easy-
On Cap onto the connector pin, until the Reaction Tube is fully located in the base.
The stainless steel Gas Outlets feature an upper and lower replaceable Nitrile o-ring as
standard with an optional Viton replacement. These O-rings may be subject to chemical
attack and will require periodic replacement.
RR91060 Nitrile O-Rings 4mm Gas Outlet - Bottom, pk 50
RR91061 Nitrile O-Rings 3mm Gas Outlet - Top, pk 50
RR91062 Viton O-Rings 4mm Gas Outlet - Bottom, pk 50
RR91063 Viton O-Rings 3mm Gas Outlet - Top, pk 50
8.8. Connect Reflux Coolant Supply
For cooled reactions, reflux cooling is not required. Please refer to the Carousel 12 Plus
Instructions for full details of the set-up and operation of reflux cooling.
Important Note
Do not attempt to dismantle the Reflux Head – THIS WILL INVALIDATE
YOUR WARRANTY. Dismantling the Reflux Head may compromise the
silicone seal between the surfaces and cause a water leak during operation.

8.9. Connect Gas/Vacuum supply
The central gas inlet and radial distribution system combined with gas tight Easy-On PTFE
Caps allows reactions to be performed under an inert (nitrogen/argon) atmosphere.
For use under an inert atmosphere attach tubing to the central quick-release coupling and
connect via a 3-way tap or stopcock to a vacuum source and inert gas supply (recommended
maximum pressure 1psi).
Then, by alternately evacuating the system and filling it with a suitable inert gas (repeating
2 to 3 times) will achieve an inert atmosphere within the tubes.
The tubes can be isolated or removed during synthesis by simply closing the valve on the
Easy-On PTFE Cap and removing the tube.
Important Note
The Reaction Tubes can be isolated or removed during synthesis by simply
closing the valve on the Easy-On PTFE Cap ensuring the other reactions
remain under controlled inert conditions.

Important Note
If all gas connector positions are not in use, unused positions can be blocked
off with a Silicone Septa to ensure a satisfactory supply of gas to all reaction
tubes.

Warning
When applying gas to the reaction station gas inlet system do not exceed 1
(one) psi as the Reaction Tube and Easy-On PTFE Caps are not rated for
pressure, (they are however suitable for applying a vacuum).
