MAINTENANCE
This chapter describes routine maintenance procedures that you should perform on a
regular basis. As the user, it is your responsibility to make certain that these procedures
are followed when necessary. Also, to keep your centrifuge in good working condition and
ensure accurate test results, we recommend that, in addition to these routine procedures,
you have the speed control, timer, rotor imbalance detector and temperature control
checked periodically by a Du Pont Service Representative or other qualified service
personnel because occasionally, these controls may need to be recalibrated. If further
service is needed, contact your local representative for SORVALL

Products.
WARNING
Because of the high voltages in this centrifuge, only personnel trained in
electronics should test or repair the electrical circuits.
If hazardous materials have been processed in the centrifuge, take all
necessary precautions when cleaning or servicing the centrifuge to avoid
personal exposure to contamination.
Inspection and Cleaning
a. Inspection
Inspect the centrifuge each week for signs of wear, encrusted biological deposits, and
general cleanliness. Follow the cleaning procedures described below when necessary.
b. Cleaning
Rotor Chamber
The rotor chamber should be kept clean and wiped dry. Wash the rotor chamber with
a mild, nonalkaline dishwashing liquid, then rinse and dry with a soft absorbent cloth.
Use 70% ethanol to disinfect the rotor chamber or a 2% glutaraldehyde solution to
sterilize it. For general radioactive decontamination, use a solution of equal parts of
70% ethanol, 10% SDS, and water. Follow this with ethanol rinses then deionized
water rinses. Dry with a soft absorbent cloth. Dispose of all wash solutions in proper
radioactive waste containers.
