Key Features<br> Large Capacity: The centrifuge can hold six tubes, each with a capacity of 0.004gal. It can meet the need for simultaneous centrifugation of large volumes of mixtures and improve the working efficiency.<br> Low Noise Level: This centrifuge features a DC motor that produces a lower noise level of no more than 60db during operation, creating a comfortable and quiet working environment for you.<br> Small Size: Its small size, which takes up a desktop area of only 9.1*10.2in, allows it to be placed on most desktops without taking up much space.<br> Adjustable Speed Knob: This machine has a knob to set the speed(0-4000rpm/min), so you can choose your desired speed within the set range to separate the different liquids from the solid particles or the liquid mixture of different densities.<br> Adjustable Time Knob: It has a knob to set the time, so you can choose your desired time within the time range(0~60min) to achieve different levels of separation.<br> Alarm Design: This centrifuge is equipped with an alarm to remind you when the set centrifugal time is over, which is convenient for you to keep track of its progress.<br> Application<br> This instrument is widely used in hospitals, chemistry, and biochemistry laboratories for qualitative analysis of serum, plasma, immune, etc.<br> How to Operate<br> 1.Turn on the cover.<br> 2.Put the simple into the rotors.<br> 3.Press the power button.<br> 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.<br> 5.Set the time and speed to "0".<br> Specification<br> Material: ABS<br> Color: White<br> Model: 900-2<br> Rated Voltage: AC220V<br> Fuse: 10A<br> Total Instrument Power: 30W<br> Max.
