Crescent-shaped stirring rotors, PTFE
The stirrer shafts consist of a PTFE-jacketed, stainless steel shaft and a stirrer paddle made of solid PTFE. The stainless steel core assures stability of the stirrer shaft and allows safe attachment of the stirrer chuck. Thanks to the thick PTFE coat and the paddle made of solid PTFE, the medium will only come into contact with PTFE. High chemical resistance makes it almost universally suitable. PTFE is extremely nonstick so that residues are repelled from shaft and paddle. The stirrer shafts are similar in size to (KPG) glass stirring rods and are therefore interchangeable easily.Operating temperature: -200°C to +250°CAdditional sizes and accessories are available on request.Information on the mixing effects of the different stirring geometries can be found in the descriptions of the stainless steel stirring rotors.The semi-circular shape of the paddle is ideal for mixing in round-bottom flasks. The pivoting blade allows insertion into vessels with narrow necks and/or ground joints.

Additional Stirrer Blades for Bola Stirrer Shafts, PTFE
Useful extension to the existing range of Bola stirrer shafts. The additional blades can optionally be fixed in your preferred position on every stirrer shaft with diameter 8,10 or 16 mm (a flat spanner is included). The stirrer blades are entirely made of PTFE, the mounting devices are made of a special PTFE-compound. A high chemical and thermical (-200 to +250 °C) resistance is assured. This "building block system" allows the user to define a stirrer of their own special requirements.

Impellers VISCO JET®
The worldwide patented VISCO JET® Mixing System is the result of the so-called cone-principle. Turbulent flows are created at the taper end by acceleration, displacement and retardation. These flows advance through the stirred medium and result in the new dynamic mixing motion.One system for literally all mixing tasks for low to high viscosity mediaPatented cone-principle creates even at low speeds a turbulent flow which is unique to the VISCO JET®Even with high-viscosity media and gels which naturally do not mix by using common impellers you will observe an immediate flow through the entire beakerThis technology allows for de-gassing of gels while preventing air intake and foamingReduce process times significantly while performing the best mixing result everThe stirring systems are made of stainless steel (V4A or AISI 316 Ti) or polyoxymethylene (POM).Other versions available.
