TD4C centrifuge machine is better than others, LCD screen, 4000rpm, brushless motor, lighter weight with larger capacity. how to use it Please read the user manual carefully before using the machine the benchtop centrifuge for up to 15ml tubes, please order the correct tubes to use. Note: The amount of sample added to the angle rotor centrifuge tube is no more than 80 of the capacity of the centrifuge tube. Please do not use broken rotors, they may explode. Specifications: Power supply-- 220V Noise-- 65dba rotor Capacity-- 8 x 15ml (can use 5ml 8ml 10ml 15ml centrifuge tube 5ml 8ml 10ml vacuum tube) Speed-- 0-4000RPM Time limited-- 1-99 minutes Centrifugal force-- 2200xg Product Size-- 32cm x 27cm x 21.5cm (13'' x 13'' x 11'') Weight-- 7kg Package includes: 1 Centrifuge 1 x manual in a bag 1 Power CableHOW TO CARE THE CENTRIFUGE: Please clean it with wipes after use, regularly check the rotors or tubes whether it is broken, and keep it in the dry space. Please keep the rotors balanced, which is good for long time use. Unplug when not in use. We focus on the quality of each product and try our best to deal with any problems. WIDE APPLICATION: Low speed desktop centrifuge is widely used in medicine, laboratory practice, research, genetic engineering, biochemistry, plant extraction, blood preparation, food processing, beauty, etc. EASY TO USE: You need to turn on the power at the back of the centrifuge, open the lid, put the samples into the rotors, they need to be the same distance, then set the time and speed you want, you can't walk away until the Speed ?reached is on the number you set, when the time shows "0" there will be a beep. We test the product many times, it is super safe and stable. INTELLIGENT OPERATING SYSTEM: When the speed exceeds 500RPM, the automatic protection function will slow down the speed, and if the cover is opened during operation, the centrifuge will stop, beep and hold the scale, protecting the samples. The machine will automatically save the previous parameters for direct use next time. UPGRADED FUNCTION: The 8 x 15ml laboratory centrifuge is a low speed centrifuge with LCD screen, you can adjust the time, speed and centrifugal force displayed on it. and the brushless motor does not need maintenance, 2200 x g, 4000 rpm, waterproof, non-slip, safe lock, they are better than cheap products, you can reset them even if they work. which can protect the samples.
