This Beckman Coulter rotor has been manufactured in an ISO 9001 or 13485 facility for use with the
specified Beckman Coulter centrifuges.

The Rotor

The SX4400 is a four-place swinging bucket rotor. This rotor carries adapters that allow
centrifugation of a wide range of tube and bottle sizes (from 1.5-mL reaction vials to 400-mL
bottles). The SX4400 rotor develops centrifugal forces that are suitable for rapidly sedimenting
protein precipitates, large particles, cells, and cell debris.
The rotor yoke and buckets are made of aluminum and are black-anodized for corrosion protection.
The buckets are run by placing them over pivot pins on the arms of the yoke. Buckets swing out to
a horizontal position during centrifugation. This rotor was tested
microbiological aerosols under normal operating conditions of the associated Beckman Coulter
centrifuge, when used and maintained as instructed. A tie-down screw is used to secure the rotor
to the drive shaft during centrifugation.
The centrifuge identifies rotor speed during the run by means of a magnetic speed sensor system in
the centrifuge rotor chamber and magnets imbedded in the rotor. The overspeed system ensures
that the rotor does not exceed its permitted speed.

Buckets and Accessories

Threaded-top buckets with screw-on transparent covers hold several sizes of labware in modular
or one-piece adapters. Each cover requires an O-ring that seats in a groove at the top of the bucket.
Although the covers are not designed to contain aerosols that may result from tube breakage, they
will contain most liquids and broken tube particles, allowing you to take appropriate precautions
before opening the covers in the event of tube breakage.
A variety of tube sizes can be centrifuged in the rotor, supported in tube adapters listed in
The adapters can also serve as tube racks in the laboratory.
* Validation of microbiological containment was done at an independent third-party testing facility (CAMR, Porton Down,
UK, or USAMRIID, Ft. Detrick, MD, U.S.A.). Improper use or maintenance may affect seal integrity and thus
containment.
