Stirrer Heads
Crescent-shaped stirring rotors, PTFE
![A click opens this product segment](/lab/shop/pic/150x150/owweb/9197121_3.jpg)
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....

Propeller stirring rotors, 3-blade, stainless steel 1.4305
![A click opens this product segment](/lab/shop/pic/150x150/owweb/s7071_2.jpg)
The 3-blade propellers produce axial flow, and reduce shear forces to a minimum, even at high stirring speeds, thanks to their optimised blade design. Recommended for medium to high speed operations.

Additional Stirrer Blades for Bola Stirrer Shafts, PTFE
![A click opens this product segment](/lab/shop/pic/150x150/owweb/6233277_3.jpg)
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....

BuddeMix Stirring System 1 - 4
![A click opens this product segment](/lab/shop/pic/150x150/owweb/s9330_1.jpg)
This novel stirring system has been conceived to mix low viscosity fluids as well as highly viscous media at slow speeds. Its special design creates inherent dynamic currents to produce perfectly homogeneous mixing results in very little time. Additional components like baffles, bottom bearings, etc. are not needed....
Centrifugal stirring rotors, 2-blade, stainless steel 1.4305
![A click opens this product segment](/lab/shop/pic/150x150/owweb/s7074_1.jpg)
The folding blades of this 2-blade centrifugal stirring rotor open with increasing speed, allowing use with narrow-neck vessels. The stirring effect it provides is similar to a standard diagonal blade stirring rotor. Recommended for medium to high speed operations....

Dissolver stirring rotors, stainless steel 1.4404
![A click opens this product segment](/lab/shop/pic/150x150/owweb/9779322_1.jpg)
The dissolver stirring rotor creates a radial flow with high turbulence. The mixture is drawn from top to bottom. High shear forces are created at the dissolver disk, which provides effective particle reduction. Recommended for medium to high speed operations....
Impellers VISCO JET®
![A click opens this product segment](/lab/shop/pic/150x150/owweb/9816595_3.jpg)
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 media
- Patented 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 beaker
- This technology allows for de-gassing of gels while preventing air intake and foaming
- Reduce process times significantly while performing the best mixing result ever
Paddle stirring rotors, stainless steel
![A click opens this product segment](/lab/shop/pic/150x150/owweb/s7075_2.jpg)
