Safety Notice
Safety Notice
• Components or accessories designed for other rotors may cause rotor mishap if used in this
rotor. Use only components and accessories that have been designed for use in this rotor. The
safety of rotor components and accessories made by other manufacturers cannot be ascertained by
Beckman Coulter. Use of other manufacturers' components or accessories in the rotors may void the
rotor warranty and should be prohibited by your laboratory safety officer. If tubes, microplates, or
other labware made by manufacturers other than Beckman Coulter are used, reduce rotor
speed to prevent breakage. The strength of glass and plastic tubes can vary between lots, and
will depend on handling and usage; we highly recommend that you pretest labware in the rotor
using water samples to determine optimal operating conditions. Scratches (even microscopic
ones) significantly weaken glass tubes.
• Do not substitute a metal fastener for the plastic tiedown nut supplied with the rotor. If a tie
down nut comes off the shaft during centrifugation, the plastic nut furnished will break apart
in the chamber, causing minimal damage to the instrument. A loose metal object could
substantially damage the rotor, chamber, and lid, and could potentially escape the chamber
into the laboratory, causing personal injury or property damage.
• The rotor must be run with a full complement of buckets and/or multiwell plate carriers
attached to the yoke. You can run four buckets, four multiwell plate carriers, or two buckets
and two carriers (with like components loaded opposite each other). If only two buckets are
loaded with blood bags, bottles, or modular disk adapters, the other two buckets should contain
at least a minimal "blank" load (e.g., empty modular disk adapters) to achieve optimal results
and to avoid rotor imbalance.
• The maximum allowable run speed (3750 rpm) listed in the rotor specifications is for operation
when all conditions are within the standard specifications (using buckets). Maximum allowable
run speed when using Micro Plus multiwell plate carriers is 3250 rpm. Do not overload the rotor
without reducing the speed (see SPEED DERATING). Failure to derate will reduce the safe useful
life of the rotor.
• If disassembly reveals evidence of leakage, you should assume that some fluid escaped the
rotor. Apply appropriate decontamination procedures should be applied to the centrifuge and
accessories.
