DetailsTransparent Cover: It is designed to observe the operation of the machine and efficiently reduce noise during operation.LCD Display: It is equipped with an LCD display that shows the exact speed and time of centrifugation, making it easy to monitor its working status.ApplicationThis instrument is widely used in chemistry, and biochemistry laboratories for qualitative analysis of serum, plasma, etc.How to Operate1. Turn on the cover.2. Put the simple into the rotors.3. Press the power button.4. Set the time first, then set the speed. When you hear a beep reminder, then set the time. It will make a beep when just in time.5. Set the time and speed to "0".SpecificationMaterial: ABSColor: WhiteModel: 900-1sRated Voltage: 110VFuse: 1ATotal Instrument Power: 50WMax.

Please do not set a high speed at the beginning. You need to set the speed from low to high2. Please put the tube containing the same amount of sample into the rotor symmetrically.3. Please do not centrifuge materials with a density greater than 1.2 g/cm³.4. Please note that it is normal for the motor to generate heat during prolonged high-speed centrifugation.5. Before you are going to stop the machine, you should adjust the governor to "0" first.6. The actual centrifuge tube capacity should not exceed 80%.
