for 30 minutes, PC and PP tubes at 121℃ （0.1kg/cm
） for 20 minutes. If a certain temperature is exceeded,
the tubes may be deformed.
When use a sterilizing chamber, please operate as follows:
(1) Place tubes in vertical position, mouths upward. If tubes are placed sideways, they may deform into an
oval shape due to gravity.
(2) Remove locking nut and lid to prevent from deformation or rupture.
(3) Wait until the sterilizing chamber cools down to the room temperature before removing tubes.
4) Conditions and life expectancy of tubes
The life expectancy of plastic tubes depends on the characteristics of samples, speed of the rotor used,
temperature applied and so on. When the plastic tubes are used for ordinary aqueous samples (pH between
5.0 and 9.0), 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.
