11.1.3 Notice
The centrifuge rotor can separate samples which density lower than 2.0 g/ml. If the separated samples density is over
2.0 g/ml, please calculate allowable speed depending on the following formula.
Allow Speed (rpm) = Maximum speed × (2.0 (g/ml) /Sample density (g/ml) )1/2
11.1.4 Autoclaving
The rotor is manufactured in high-strength aluminum alloy material and can be autoclaved: 121ć(1.0kg/cm2)20
minutes.

11.2.2 Cleaning PC tubes
PC material is low in chemical resistance against alkaline solutions. Avoid using neutral detergents with pH
higher than 9. Note that pH of some neutral detergents are still higher than 9 even if diluted according to the the
manufacturer’s instruction. Use detergent with its pH between 7 and 9.
