Product description

Ideal stirrer head for PTFE-jacketed stirrer shafts from BOLA. Consisting of capsuled drive shaft (stainless steel) with ball bearings, rotor and lower bearing made of PEEK-Compound and a Hastelloy® receiver. Requires little space due to compact construction. No leakage or memory effects due to non-porous, welded rotor. Compression fittings for safe fixing of stirrer shaft and optimum power transmission. Joint-Cone with nut (Safe-Lab) made of PTFE for easy locking and unlocking of the ground joint. Square size 6 mm for accepting an agitator or a stirrer coupling.

Product advantages

» gastight stirrer head for perfect vacuum
» stirrer shaft's height adjustable, approx. 40 mm
» also suitable for shortened stirrer shafts
» powerful transmission of up to 90 Ncm
» excellent chemical resistance
» no grease required / save to run dry
» high speed of up to max. 1.500 rpm
» drive shaft fixed for your safety
» high durability
» easy disassembly of all parts for cleaning
» with receiver made of Hastelloy® for improved durability

Applications

>> Suitable for all BOLA Stirrer Shafts jacketed with PTFE. Ideal for reactor lids with center ground joint.
>> L1: The max. shaft length corresponds to the internal height from the top of the ground joint to the vessel bottom.

Product description

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.

Product advantages

» very low centrifugal forces due to low weight
» suitable for both left- and right-handed rotation (except for GL 10 thread: no left-handed rotation possible)
» no resonance
» simple assembly by means of screw joints with clamp rings
» chuck adaptor (length 90 mm) can be shortened by the user

Applications

Ideal for balancing misalignment of axes between stirring drive and stirrer shaft, suitable for glass, metal or BOLA stirrer shafts.

Product description

Ideal stirrer head for PTFE-jacketed stirrer shafts from BOLA. Consisting of capsuled drive shaft (stainless steel) with ball bearings, rotor and lower bearing made of PEEK-Compound and a borosilicate glass receiver. Requires little space due to compact construction. No leakage or memory effects due to non-porous, welded rotor. Compression fittings for safe fixing of stirrer shaft and optimum power transmission. Joint-Cone with nut (Safe-Lab) made of PTFE for easy locking and unlocking of the ground joint. Square size 6 mm for accepting an agitator or a stirrer coupling.

Product advantages

» gastight stirrer head for perfect vacuum
» stirrer shaft's height adjustable, approx. 40 mm
» also suitable for shortened stirrer shafts
» powerful transmission of up to 90 Ncm
» excellent chemical resistance
» no grease required / save to run dry
» high speed of up to max. 1.500 rpm
» drive shaft fixed for your safety
» high durability
» easy disassembly of all parts for cleaning
» receiver made of borosilicate glass for universal chemical resistance

Applications

» Suitable for all BOLA Stirrer Shafts jacketed with PTFE. Ideal for reactor lids with center ground joint.
» L1: The max. shaft length corresponds to the internal height from the top of the ground joint to the vessel bottom.
