2. Overview
The Flexel ® Palletank ® for LevMixer
single-use mixing solution using the market
leading LevTech ® levitated LevMixer
and Sartorius Stedim Biotech Flexel
®
for LevMixer combined with the especially
developed cubical mixing tank based on
the proven Palletank ® technology. Major
improvements in bag installation and han-
dling paired with the efficiency and speed of
traditional mixing systems make the Flexel
® ®
Palletank for LevMixer the disposable
mixing system of choice in the biopharma-
®
ceutical industry. The Flexel
LevMixer ® is able to mix in sterile disposable
hermetically sealed standard or custom bags
with volumes up to 1000L.
The Flexel ® Palletank ® for LevMixer
comprises three main components:
® ®
1. Palletank for LevMixer or Palletank
Jacketed for LevMixer ®
2. LevMixer ® drive unit
3. Flexel ® Bag for LevMixer ®
Precautions for use
The Palletank ® internal surfaces must be
smooth, free of any particles and dry before
®
inserting the Flexel Bag for LevMixer
Traces of cleaning agents left on the
Palletank ® can potentially damage the bag.

3. Principle of Operation

® is a new The Flexel
on non-contact magnetic coupling between
® impeller conventional permanent magnets in the
® Bag impeller and superconducting material in the
drive. Superconducting material has the abi -
lity to trap the magnetic field generated by
the permanent magnets and "lock the mag-
netic field in memory" in an equilibrium
position.

between the permanent magnet and super-
conductors. The superconducting material
traps the magnetic field from the magnet,
resulting in stable mechanical coupling
without physical contact.

.
The trapped magnetic field behaves like
mechanical springs; if the magnet is moved
up, down or sideways by outside forces (e.g.,
gravity or angular torque), it will tend to be
pulled back to an equilibrium position. The
peculiar nature of magnet-superconductor

interaction ties the two bodies together

resulting in a very stable mechanical couple

peculiar stability cannot be attained in con-
(impeller)
ventional mixer designs that employ two
FXC114525 permanent magnets. In these mixers, the
two magnets strongly attract one another
FXC113382
and exert that force on the bearing in the
FXC113383 impeller. Thus, the magnet-superconductor
couple is the basis for a revolutionary design
FXC114524
of the non-contact magnetic levitation
FXC114526 mixer.

The Cryogenic temperatures (approx.
–200°C) required for the superconducting
material are achieved by an internal
cryocooler (Sterling cycle refrigerator),
which operates on 230V 50|60 Hz
AC power.
