100 different designs of Bohlender stirrer shafts

Stirrer shafts by Bohlender are protected against breakage by solid stainless-steel core and universal chemical resistance - the thick fluoroplastic-jacket assures the medium is exposed only to PTFE

Bola-stirrer shafts consist of a PTFE-jacketed stainless-steel shaft and a stirrer blade made of solid PTFE.

The stainless-steel core provides high mechanical stability that is required for the chucks of the agitators.

The stirrer blade is firmly fastened with the shaft.

When stopping the agitator, the blade will not be unscrewed by the medium running after.

Stirrer shafts are suitable for right or left hand rotations and all parts exposed to the medium are made of fluoroplastics.

Thus, the stirrer shafts are resistant to virtually all chemicals and can be used at high operational temperatures.

Bola stirrer shafts offer many advantages over glass or stainless steel.

Unbreakable - glass stirrer shafts commonly used in laboratories are very fragile.

Dropping of the stirrer shafts, stirring solid materials in the medium or too much power transmitted from the agitator to the medium can cause broken glass.

Stirrer shafts by Bohlender are protected against all these possibilities of breakage by virtue of their very solid stainless-steel core and universal chemical resistance - the thick fluoroplastic-jacket (not a thin layer which can easily be damaged) assures that the medium is exposed only to PTFE.

Thus, the stirrer shafts are resistant to virtually all chemicals.

Fluoroplastic-jacketed stainless-steel stirrer shafts can be used in extreme applications, where the chemical resistance of PP (polypropylene), glass or stainless-steel stirrer shafts is not adequate Temperature Resistance - Stirrer shafts made of PP (polypropylene) become deformed at temperatures exceeding 100C and then cannot be used any longer.

Fluoroplastic-jacketed stainless-steel stirrer shafts can be used at temperatures up to +250C (without any effects on their chemical resistance).

Non-adhesive - the surfaces of glass and stainless-steel stirrer shafts allow the adhesion of mediums (in particular such as dyes and glue).

This is not the case with the stirrer shafts by Bohlender.

PTFE is extremely non-adhesive and thus, eliminates adhesion of materials such as dyes or adhesives.

Interchangeability - At present most stirrer shafts used in laboratories are made of glass.

Fluoroplastic-jacketed stainless-steel stirrer shafts by Bohlender are available with the same diameters, lengths and KPG surface qualities as stirrer shafts made of glass.

Thus, the user can easily replace his glass stirrer shaft with a fluoroplastic-jacketed stirrer shaft, without having to change his existing agitators/driving machines, couplings and guiding devices.

A range of stirrer guides and bearings as well as magnetic stirrer couplings are available.
