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....
