A.SAFEGUARDS & PRECAUTIONS
1. Read and follow all instructions in this manual carefully, and
retain this manual for future reference
2. Do not use this instrument in any manner inconsistent with
these operating instructions or under any conditions that exceed
the environmental specifications stated.
3. Be sure the power supplied to this instrument matches the
specifications indicated on the control box and described on
the Copy of Equipment Nameplate page.
4. If the drive unit is transported or stored in temperatures colder
than the operating environment it is necessary to wait 1-2 hours
to equalize the internal temperatures of the drive unit before
powering on.
5. Be sure all power is disconnected before opening, assembling
or disassembling the superconductive drive unit or its control
box.
6. For full compliance with CE specifications, be sure the
appropriate ground connection is made.
7. For technical assistance contact the sales organization from
which you purchased the product or Pall Life Sciences directly
8. Each LevMixer®mixing bag contains a magnetic impeller,
which is a source of strong magnetic field within close proximity
(12 inches) of the impeller. PEOPLE USING ANY ELECTRONIC
MEDICAL DEVISES, SUCH AS PACEMAKERS, SHOULD NOT BE
INVLOVED IN THE CLOSE HANDLING OF LEVMIXER MIXING BAGS,
MAGNETIC CHARGERS, IMPELLERS OR TEST IMPELLERS.
Document #: 020-17475-00 Revision: E Page #: 3 of 63
9. Keep the supplied magnetic shields on bags, magnetic
chargers, and impellers when not in use.
DO NOT open the machine or control box while the Drive Unit is
plugged in.
DO NOT submerge the drive in water. The unit outer surfaces
may be cleaned and sanitized by wiping with a mild detergent
solution.
DO NOT cut the ground plug.

D. OVERVIEW
The LevMixer®utilizes a levitating impeller in a sterile closed bag, driven and levitated by
asuperconducting drive. The LevMixer® is able to mix within sterile disposable
hermetically sealed standard or custom bags with volumes up to 2000L.
The mixing system hardware has three major components:
1. Superconducting drive unit
2. Elevated Retaining Tank (either on dolly or with integrated legs)
3. Drive Port that couples drive unit with bag
The mixing system can accommodate a variety of standard and custom-designed
single-use mix bags available from PALL LifeSciences.
E. PRINCIPLE OF OPERATION
The LevMixer®’s mixing technology is based on non-contact magnetic coupling
between conventional permanent magnets in the impeller and superconducting
material in the drive. Superconducting material has the ability to trap the magnetic
field generated by the permanent magnets and “lock the magnetic field in memory” in
an equilibrium position.
Figure 1: Noncontact magnetic coupling between the
permanent magnet and superconductors. 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-
Document #: 020-17475-00 Revision: E Page #: 7 of 63
superconductor interaction ties the two bodies together resulting in a very stable
mechanical coupling with finite equilibrium separation. This peculiar stability cannot be
attained in conventional mixer designs that employ two permanent magnets.
The Cryogenic temperatures (approx. –200oC) required for the superconducting
material are achieved by an internal cryocooler (Sterling cycle refrigerator).

bearing (red in far left picture) should rest on the surface of the levitation head of the drive unit.

Magnetic Charger & Test Impeller Chart:
*Note: the appropriate magnetic charger must be used to set the drive machine for
use with the corresponding impeller. The machine will not properly drive an impeller
which does not have the corresponding magnet configuration.
