BOLA PTFE Covered Stirrers ...

Range of PTFE covered stirrers with stainless steel PTFE encapsulated shafts and PTFE blades

BOLA PTFE Stirrer Blades ...

Range of PTFE stirrer blades for fixing to stirrer shafts

BOLA Magnetic Stirrer Heads ...

C450 Gastight permanent magnetic coupling with ball bearing encapsulated in ceramics and square connection for cardan joint. PTFE cone size 29 with release nut made of PTFE with glass fibre for easy removal of the ground joint.
All products which are exposed to the medium do not contain any metals. The 8 mm shaft guide provides guidance without friction of stirrer shafts up to a speed of 800 rpm. The stirrer head can also be fixed directly into the chuck by mounting the included metal adaptor on the square connection (6 mm).
C463 BOLA Conductors for Magnetic Stirrer Heads, Glass.
C502/C504/C512 BOLA Magnetic Stirrer Heads (G-MRK), PTFE Perfect combination of drive shaft with ball bearings, rotor and lower bearing made of PTFE/PEEK and a conductor made of borosilicate glass. Requires little space due to compact construction. No leakage or memory effects due to non-porous, welded rotor. This rotor holds the stirrer shaft by means of three stud screws which are fixed in the counterbores of the stirrer shaft. This provides optimum power transmission and a safe fixing. The 6 mm square can be fixed into the stirrer coupling or into the agitator.
C520/C522/C530/C532/C540 Perfect combination of drive shaft with ball bearings, rotor and lower bearing made of PTFE/PEEK and a conductor made of borosilicate glass. Requires little space due to compact construction. No leakage or memory effects due to non-porous, welded rotor. This rotor holds the stirrer shaft by means of three stud screws which are fixed in the counterbores of the stirrer shaft. This provides optimum power transmission and a safe fixing. The 6 mm square can be fixed into the stirrer coupling or into the agitator

BOLA Stirrer Coupling ...

Made of POM, a plastic material with good mechanical strength. For compensation of a misalignment of axes between stirrer shaft and stirring drive of up to 10 mm. Powerful transmission of max. 300 Ncm and suitable for a speed of up to 1200 rounds per minute and for both left- and right-handed rotation (except for version with female thread GL 10).
Different versions for assembly of glass, metal or PTFE coated shafts by means of a clamp screw to accept shafts with O.D. 4.0 mm, 6.5, 8.0 or 10.0 mm. An additional reducing sleeve for O.D. 6.5 / 8.0 mm is included in delivery.
Shafts with male thread GL 10 are screwed directly into the respective model with female thread GL 10. The coupling with inner square SW 6 is simply pushed on its counterpart.
The chuck adaptor is fixed directly in the drill chuck of the stirring drive and can be shortened if necessary.
