Centrifuge machine is a common laboratory equipment that have been used in many clinical laboratory, hospital, research centre and industrial laboratory. The main purpose of centrifuge is to separate various component from a solution.
It utilizes the sedimentation principle which involve the centrifugal force from the rotor speed and density to separate the component according to their size, shape, and viscosity. The centrifugal force is proportional to the rotation rate of the rotor. During this centrifugation process, the centrifugal force will cause the denser component to form a sediment (pellet) below the centrifuge tube while another low low-density component (supernatant) will rise-up.
Centrifuge rotor categories:
1. Fixed-angle Rotor Fixed angle rotor holds the tube in rigid manner as exactly same fixed angle, usually 45 degrees angles all the time with high rpm for a high separation of samples. This rotor is commonly used in research or microbiology laboratory for pelleting application of bacteria, yeast, or mammal cells debris. When centrifugal force is applied, the mixture in the tube will reorient, hence causing denser component (pellet) to form a sediment in bottom of the tubes.
2. Swing-out Rotor Swing-out rotor does not rigidly attach to the bucket that holding the tube. During the centrifugation process, applied centrifugal force causing the bucket to spin horizontally at 90 degrees angle. This swing-out bucket rotor taking advantages by separating the sample mixtures into a gradient density, thus ideal for separation of multiple mixtures in a solution such as blood. The longer the path length for permit allow a better separation of the mixtures.
Centrifuge comes with different categories and features to cater various laboratory purposes and applications. Below are the types of centrifuges according to their necessities:
• Micro-centrifuge This compact benchtop centrifuge is use to accommodate small volume tubes ranging from 0.2ml PCR tubes to 2ml microcentrifuge tubes. Gyrozen mini model can be operated at maximum speed of 13,500 rpm and offers an interchangeable rotor to facilitate the use of larger tubes along with the smaller ones.
• Low-speed centrifuge Low-speed centrifuge is a common type used in the clinical and hospital laboratories for routine separation of blood samples and other biological samples. This centrifuge usually operates at maximum speed of 4000-5000 rpm, allowing for excellent mixtures separation without causing trauma and affecting the integrity of the samples. They are usually operated under room temperature as they are not provided with a system for controlling the speed or temperature of the operation.
• Multipurpose high-speed centrifuge This benchtop multipurpose centrifuge, can be operated at maximum speed of 15,000 rpm with large volume capacity and comes with both refrigerated and non-refrigerated type. Gyrozen 1248 and 1248R is all-in-one solution for various sophisticated laboratory application to increase productivity of routine lab analysis. 1248R designed with a temperature control function range from -20 ℃ to 40 ℃ to protect temperature sensitive samples such as live cells, DNA, RNA, and proteins.
• Floor standing high-speed centrifuge If bench space is a limitation, then a floor standing type of centrifuge would be beneficial. Gyrozen 1238R is a floor standing refrigerated centrifuge ideal for large volume daily working laboratories as they can hold a lot more loads at one time. The maximum speed is 12,000 RPM with an ergonomic height of 84cm for easy samples load and unload. It is equipped with various features, large capacities, and versatile rotor selection for various centrifuge application.
