Product description
PTFEGlossaryPTFEPolytetrafluoroethylene -encapsulated magnetic core made of a very strong magnetic material (rare earth magnet samarium-cobaltGlossarysamarium-cobalt Alloy of the rare earth metal samarium and the metal cobalt which is used as permanent magnet. These magnets resist temperatures up to 250°C or 350°C, are very hard, brittle and resist to extremely opposing electromagnetic fields. A demagnetisation can virtually be excluded. ), torque loads transmitted are about 4 times larger than those of conventional magnetic stirring bars. No risk of demagnetization, sterilisableGlossarysterilisable Items which can be released from microorganisms of any development stage by heating or by applying chemicals are sterilisable. All BOLA vessels made of PTFE, FEP and PFA are sterilisable up to 121 °C. , extremely smooth surface avoiding contaminations, universal chemical resistance.

Applications
They are mainly used for agitating viscous liquids or for bridging larger distances between the magnetic stirring machine and the magnetic stirring bar. Optimum mixing in vessels with a big volume or in tall graduated cylinders
