rotational wand mixing technology provides non-invasive mixing inside sterile
plastic bags. It is based on rotating of the curved rod pre-introduced in the sleeve of the
mixing bag. The rod is separated from the processed sterile fluid by sleeve which is
hermetically sealed on one end. Rotation of rod induces rotational motion of the sleeve
due to flexural shape changes. Flexural rotational motion of the sleeve results in
efficient mixing inside the bag.
Figure 1:
Rotational wand is pre-introduced inside the sleeve of the bag. 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 bag.
