MAIN FUNCTION This centrifuge can be used in various fields such as biology, medicine, chemistry, food, education, beauty, life science, etc.It mainly be used for the appraisal radioactivity and separate cell or particle. 6 Tubes More Efficency The centrifuge can hold 20mlX6 tubes one time.On the top of centrifugal head equipped with cover, effectively reduce noise and air resistance. Timing and Speed Electric Laboratory Centrifuge Machine with two knobsl to control speed and time.The speed ranges from 0-4000rpm and it has a 0 to 60 minute timer. Anti Skip Sucker There are three suction cups installed on the foot of the machine, which makes the machine more stable and not easy to slip when running. Bench-Top Centrifuge Low noise, smooth operation and easy to use.Compact and quiet enough to install in an office or classroom as well as in laboratories and medical settings. Voltage AC110V 60 HZ Power 25W Max Speed 4000r/min Time Rang 0~60min Capacity 20ml×6 Max relative Centrifugal Force 1790×g Centrifugal Capacity 20ml per tube Dimensions 24.5x23x10.5cm Using Description 1.Put the machine on a level and strong table and keep the woring room clean, dry and ventilated. Indoor tempeture 5-32°is ok.2.Clean die rotor and container before operating.3.Put the test tube(with the same weigjt) into the centrifugal hole.4.Put down the cover of the machine, adjust the timer as you requirement and turn on the power switch.5.Adjust the speed knob as your requirement.6.The motor iwll automatically stop supplying the electricity if oprn the cover during the working time.7.After finishing the work, adjust file speed knob to file lowest position and turn the timer to 0, and then cut off the power supply.8.Clean the container and rotor, then put dowen the cover.
