Autoclave Engineers have added a new reactor to their extensive range of custom configurable stirred reactors (available in the UK through Merrow Scientific).
Featuring the inline Mag3 magnedrive this results in a very small footprint stirred reactor that can easily be configured to suit many research applications. Rated to 454degC and 227bar using metal to metal engineered seals throughout this unit can be easily integrated with MFCs, back pressure regulators, automated sampling systems and other devices.
Available in a range of materials and with 10 ports that can be set up with whatever fittings are required, plus a wide range of catalyst baskets.
Further information can be seen on the Mini-Ezeseal HTHP page or by contacting Merrow Scientific

From time to time we get a call from one of our customers who has an Autoclave Engineers stirred reactor in their lab to let us know that the system has started to make a weird squeaking noise.The first question we ask is “when did you last check the bearings?” – this is normally met by silence on the other end of the line… (so you’re not alone!!)
So let’s start off with a few basics, beginning with a photo of an example reactor, the mini reactor from AE (small scale stirred reactor rated to 200 bar and 315degC):
As you can hopefully see the arrangement is something like this:
- » Inline motor at the top, which is connected to the
- » Magnedrive magnets, these spin round at your required and specified rpm and through the cover (via the magnetic field coupling) accurately rotate the
- » Encapsulated inner magnet assembly which leads to the
- » Shaft and impeller
So the cover means that the reactor is a completely sealed environment and the use of the magnets allows accurate and positive control of the stirring of the product inside the reactor.(hope that makes sense!)This is the same throughout the range of reactors although sometimes the motor can be bigger and linked to the magnedrive via a belt.
