8.3 Pulse operation This function is used to remove the residual samples adhered to the interior of the tubes or for quick spins. Note:The button works only while the rotor stopped and the door is locked. (1) Turn on the power switch and load the rotor to the shaft, tighten the rotor lid and make sure it is in secured position, and then close the door. (2) The centrifuge gets into preparation mode and displays last running values.The values can be reset. (3) Press Pulse knob and hold, the centrifuge will speed up to the setting speed. While releasing Pulse knob during acceleration, the centrifuge will start to decelerate and stop.

9. Maintenance ！CAUTION ● If do not follow the recommended instructions for cleaning or disinfecting may damage the centrifuge. (1) Centrifuge ● If the centrifuge is exposed to ultraviolet rays for a long time, the color of the door may be changed or the label may be came off. After using, cover the centrifuge with a piece of cloth to protect it from direct exposure. ● If the centrifuge needs cleaning, clean it with a cloth or sponge moistened with a neutral detergent solution. ● Sterilize the centrifuge by wiping with a cloth moistened with 70% ethanol solution. (2) Rotor chamber

！CAUTION ● Do not directly pour water, neutral detergent or disinfectant solution into the rotor chamber, otherwise fluids may leak into the drive units and cause corrosion or deterioration to the bearings. ● If the rotor chamber needs cleaning, clean with cloth or sponge moistened with a neutral detergent solution. Sterilize the centrifuge by wiping with a cloth moistened with 70% ethanol solution. (3) Drive shaft ● We recommend regular maintenance for drive shaft. You can wipe the drive shaft with soft cloth, and then apply a thin coat of silicon grease. (4) Door ● Clean and sterilize the door using the same method as the section(1)above. (5) Rotor ● To prevent corrosion, remove the rotor from rotor chamber. If not in use for a lone term, then detach the rotor lid and turn upside down to dry the tube holes and keep clean. ● For sample leaks in the rotor, rinse the rotor with water. Apply a thin coat of silicon grease to the rotor when it is completely dry. ● The rotor should be checked every 3 months to ensure the tube and rotor holes keep are clean and apply a thin coat of silicon grease.

11.2.3 Autoclaving PA、PC and PP tubes PA begins softening at about 120℃, PC and PP at about 130℃. Autoclave PA tubes at 115℃（0.7kg/cm2）for 30 minutes, PC and PP tubes at 121℃（0.1kg/cm2）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 shapedue 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. 11.2.4 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 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 RCF Relative Centrifuge Force (RCF) can be determined with the following calculation formula. RCF = 1.118 × r × n2 × 10-5 R - rotating radius, unit: cm; n - rotating speed, unit: rpm
