Connection couplings between stirring motor and magnetic stirrer coupling

Suitable for stirring tasks under vacuum. • Homogenising • Dispersing • Suspending • Gassing The S1 and S2 design with standardised ground joint (vacuum-proof, unpressurised) Magnetic stirrer couplings with NS 29/32 (S1) or NS 45/40 (S2) joint are specially designed for use in flasks and glass reactors with ground joint connections. The encapsulated inner magnet couples to the external drive magnet bell and provides the drive force. This process involves absolutely gas-tight stirring. The sealing takes place via O-rings on the conical part and is made of FKM as standard. Alternatively, these can also be equipped in FFKM of various qualities on request.

Suitable for stirring tasks under vacuum and pressure. • Homogenising • Dispersing • Suspending • Gassing The F design with flanges DN15 and DN50 (vacuum-proof, pressure-resistant up to 10 bar) Magnetic stirrer couplings with flanges DN 15 or DN 50 are intended in particular for use on glass reactors, thin film evaporators and extraction columns. This design is not only vacuum-proof but can also be used for applications with overpressure of up to 10 bar. Standard flat gaskets, e.g. made of PTFE, can be selected as seals. Variants in special materials such as Hastelloy C22, C276, B3 are available on request. Other flange sizes and systems such as KF and TriClamp can also be realised.

• Homogenising • Dispersing • Suspending • Gassing The G design (vacuum-proof, pressure-resistant up to 700 bar) Threaded magnetic stirrer couplings are the first choice for stirring processes under high to very high pressure. This design can be used for applications up to 200 bar (in the variant made of high-temperature-resistant alloy A-286, 1.4980 even up to 700 bar). Variants in special materials such as Hastelloy C22, C276, B3 are available on request.

• Homogenising • Dispersing • Suspending • Gassing The G-V design with thread (vacuum-proof, pressure-resistant up to 200 bar) The G-V design offers all the technical specifications of the G versions, but is additionally equipped with a side gas flush connection for gas flushing and inertisation. A suitable gas flush valve is included in the scope of delivery and is already pre-assembled.
