SAFETY NOTICES
Using cleaning or sterilization method other than recommended in this instruction manual
may cause corrosion or deterioration of this centrifuge. Refer to chemical resistance chart
attached to the rotor or contact Hitachi Koki. (Chapter4)
For sterilization of the surface of the centrifuge and the rotor chamber, wipe them with a cloth
dampened with 70% ethanol. Using the method other than the above method might cause
corrosion or deterioration of the centrifuge. Refer to the chemical resistance chart provided
with the rotor, or contact Hitachi Koki.
While we recommend that 70% ethanol is used for sterilization, no guarantee of sterility or
disinfection is expressed or implied. When sterilization or disinfection is a concern, consult
your laboratory safety officer regarding proper methods to use. (Chapter4)
Do not pour any solution such as water, detergent and disinfectant directly into the rotor
chamber. Otherwise, the bearings of the drive unit may be corroded or deteriorated.

Clean the inside of the drive hole (crown hole) of the rotor and the surface of the drive shaft
(crown) of the centrifuge once a month. If the drive hole or the drive shaft is stained or any
foreign matter is adhered, the rotor may be improperly installed and come off during
operation. (Section4-2)
Your ultracentrifuge can be damaged if connected to a wrong voltage. Check the voltage
before plugging the ultracentrifuge into a power source. (Chapter6)
Be sure to remove the rotor from the rotor chamber when centrifuge is moved.
After installation and before any test-run, this ultracentrifuge always needs the internal check
by a Hitachi Koki authorized sales/service representative. (Chapter6)
