Magnetic stirring bars, PTFE, triangular, Spinstar®

Triangular stir bars can be used for faster reaction times and smooth mixing of small samples in conical-bottom vials of the Thermo Scientific™ Reacti-Therm™ Derivatization System. The stir bars provide simultaneous stirring of samples in multiple vials when used with a Reacti-Therm Heating/Stirring Module equipped with appropriate Reacti-Block Aluminium Blocks.
