PTFE-encapsulated magnetic core (Alnico5) axially mounted in a guide cage made of PTFE, universal chemical resistance. Autoclavable at 121 °C. Applications: No shear action on the bottom of the beaker, smooth running in glass beakers also on an uneven bottom. The cage acts like a baffel and thus provides optimum mixing results.
