Operation ® SORVALL Centrifuges Table 3-1. Controls and Indicators (continued) (keyed to figure 3-1) Item Name Function REV/MIN x 1000 Indicates actual rotor speed from 0 to 6000 rpm ±100 rpm. indicator OPEN light* Lights at the end of the run to indicate that the door may be opened.
Operation ® SORVALL Centrifuges Air flow through the T6000B centrifuge is designed to minimize increase in rotor temperature. Air enters through an opening in the center of the lid and exits through the exhaust duct at the top of the rotor chamber. WARNING Blocking the air flow entering and/or exiting the T6000B rotor chamber will cause an increase in the temperature within the rotor chamber.
Operation ® SORVALL Centrifuges b. Precooling the Centrifuge Chamber Only If the rotor has been precooled outside of the chamber (e.g., in a refrigerator or cold room), the chamber should be precooled before the run. With the chamber door closed, set the CHAMBER TEMP° C dial to the temperature desired.

Operation ® SORVALL Centrifuges To prevent rotor failure, the total contents of any compartment, including specimen, tubes, cover, and adapters (if used), must not exceed the figure given on page 1-2 unless rotor speed is reduced proportionately. Strict adherence to the maximum allowable compartment mass or reduced speed is required to prevent rotor failure.
Maintenance ® SORVALL Centrifuges CAUTION Chlorides are extremely harmful to aluminum alloy rotors and can cause stress corrosion cracking. Therefore, if chlorides are used to disinfect the chamber, be sure to rinse the chamber thoroughly with water to remove all of the chloride cleanser.
Maintenance ® SORVALL Centrifuges Figure 4-1. REV/MIN x 1000 Indicator Adjustment Motor Brush Inspection and Replacement Unplug the centrifuge power cord. Remove the four screws from the access cover and remove the cover. Remove the plastic brush caps from the motor with a screwdriver, and pull the brushes from their holders, noting orientations.
Maintenance ® SORVALL Centrifuges in immediate brush burn and commutator pitting and will severly limit the life of the new parts. CAUTION Do not stone or burnish the commutator as this will increase brush wear and may result in smear metal on the surface of the commutator. Do not allow brushes to wear to the point where they do not make contact with the commutator.
If a centrifuge or rotor that has been used with radioactive or pathogenic material requires servicing by Du Pont personnel, either at the customer’s laboratory or at a Du Pont facility, comply with the following procedure to ensure the safety of all personnel:...
