AseptiMix™ VB Vented Bottle Mixer Assemblies

mdi AseptiMix™ VB are gamma-sterilized vented bottle mixer assemblies, suitable for mixing, safe transfer, and storage of biopharmaceutical products and reagents. The assembly does not require any additional hardware and can directly be placed on a magnetic mixer for mixing with a stir bar or impeller placed inside.

The stir bar/impeller inside the mixer assembly has wide chemical compatibility and it ensures the proper mixing of solution without any particle shedding.

These assemblies are fitted with a self-supporting lightweight, sterilizing grade 0.2μm PVDF vent filter to prevent ingress of microorganisms during filling and removal of high-value products.
