3) Notice
⚫
The centrifuge rotor can separate samples with a density lower than 2.0g/ml. If the samples density is
over 2.0g/ml, please calculate allowable speed depending on the following formula.

Table 12-2 Cleaning and sterilizing conditions for tubes
1) 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 manufacturer’s instructions. Use detergent with its pH between 7 and 9.
