11.2.4 Condition and life expectancy of tubes
The life expectancy of plastic tubes depends on the characteristics of samples, speed of the rotor used, and
temperature applied, and so on. When the plastic tubes are used for centrifuge of ordinary aqueous samples
(pH between 5 and 9), their life expectancies are defined as follows.
Be operated at the maximum speed:
High quality tubes (PA、PC、PP): 30-50 operations
Ordinary tubes(PA、PC、PP): around 10 operations（Using in low speed can extend the tube life）.
Life expectancy of tubes also depends on the pretreatment conditions such as cleaning and sterilization,
lifetime can be cut down.
Notice: Do not use damaged or cracked tubes.
12. Calculate Relative Centrifuge Force(RCF)
Relative Centrifuge Force (RCF) can be determined with the following calculation formula.
RCF=1.118×r×n

R—rotating radius, unit: cm; n—rotating speed, unit: rpm
