Overview
The Wand Mixer single-use technology (SUT) biocontainer mixing system is a revolutionary mixer that provides
efficient mixing utilizing a patented rotational wand technology in a sterile, closed SUT biocontainer. The Wand
Mixer system can mix in sterile single-use hermetically sealed SUT biocontainers ranging in nominal volume from
5 L to 200 L.
The Wand Mixer system consists of a bench top or floor-based drive, a plastic or stainless-steel tank to support the
SUT biocontainers, a rotating stainless-steel wand for mixing and a coupling assembly to connect the wand to the
drive and SUT biocontainer.
The Wand Mixer can accommodate a variety of standard and custom-designed single-use mixing biocontainers
available from Pall Corporation.

Principle of Operation
The Wand Mixer single-use biocontainer mixing technology provides non-invasive mixing inside sterile plastic
biocontainers. The technology is based on rotating a rod of predetermined shape introduced in the sleeve of the
mixing biocontainer. The rod is separated from the processed sterile fluid by a sleeve that is hermetically sealed on
one end. Rotation of the rod induces the rotational motion of the sleeve due to flexural shape changes. The flexural
rotational motion of the sleeve results in efficient mixing inside the biocontainer.

Once rotation of the wand is activated by external drive, sleeve performs rotational motion based on its flexing. The
mixing procedure is non-invasive leaving the processed fluid contained in sealed biocontainer.
