in this instrument nor handle or store them within the 30-cm (1-ft) clearance envelope surrounding
the centrifuge.
Mechanical Safety
For safe operation of the equipment, observe the following:
• Use only the Beckman Coulter rotors and accessories designed for use in this centrifuge.
• Before starting the centrifuge, make sure that the rotor tie-down screw is securely fastened.
• Do not exceed the maximum rated speed of the rotor in use.
• NEVER attempt to slow or stop the rotor by hand.
• Do not lift or move the centrifuge while the rotor is turning.
• If a glass tube breaks inside the chamber bowl, be careful when examining or cleaning the
gasket or chamber, as sharp glass fragments may be embedded in their surfaces.
• NEVER attempt to override the door interlock system while the rotor is spinning.
• Maintain a 7.6-cm (3-in.) clearance envelope around the centrifuge (secured with antirotation
kit) while it is running. During operation you should come within the envelope only to adjust
instrument controls, if necessary. Never bring any flammable substances within the 30-cm (1-ft)
area surrounding the centrifuge. Never lean on the centrifuge or place items on the centrifuge
while it is operating.
Chemical and Biological Safety
Normal operation may involve the use of solutions and test samples that are pathogenic, toxic, or
radioactive. Such materials should not be used in this instrument, however, unless all necessary
safety precautions are taken.
• Observe all cautionary information printed on the original solution containers prior to their use.
• Because spills may generate aerosols, observe proper safety precautions for aerosol
containment.
• Handle all infectious samples according to good laboratory practices and methods to prevent
the spread of disease. Ask your laboratory safety officer to advise you about the level of
containment required for your application and about the proper decontamination or sterilization
procedures to follow if fluids escape from containers. Biosafe containment should be used when
Risk Group II materials (as identified in the World Health Organization Laboratory Biosafety
Manual) are handled; materials of a higher group require more than one level of protection.
Because spills may generate aerosols, observe proper safety precautions for aerosol
containment.
• Other infectious samples must also be handled according to good laboratory procedures and
methods to prevent spread of disease.
• Dispose of all waste solutions according to appropriate environmental health and safety
guidelines.
It is your responsibility to decontaminate the instrument and accessories before requesting
service by our Field Service representative.
