Vacuum level in Radleys jacketed lab reactors ?
Posted: Tue 17 Feb 2015 20:11 What vacuum level can be achieved in Radleys jacketed lab reactors?
FAQ from Radleys
The vacuum obtained for a whole reaction system is typically approximately 10-50 mbar. The vacuum level that can be achieved in a specific reaction system will depend on various factors, including:
1) The type of reaction system – Reactor-Ready, Reactor-Ready Duo, Reactor-Ready Pilot and Lara have an advanced design with better sealing than a traditional reaction system, so particularly good vacuum can be achieved
2) The condition of all the seals/O-rings and piston – these are consumable parts and should be checked and replaced if required
3) The condition of other components such as stirrer guide, stirrer shaft and probes
4) Whether glass cone stoppers (optional accessories) are used to plug any unused lid ports (recommended), rather than Rodaviss sealing caps
5) Whether all joints are clean, assembled correctly and tight
6) Whether all valves are closed properly
7) Whether the vessel/lid clamp is tight enough
8) The temperature within the vessel
9) The stirring taking place (speed/viscosity etc.)
10) The reaction taking place within the vessel
11) The particular vacuum pump used (considering the pump’s ultimate vacuum and speed etc.)
12) Whether grease is used on joints
