Wondering how your washing machine removes the water from your wet laundry? You will be glad to know it’s a centrifuge!
A washing machine is a type of centrifuge. During the washing cycle, the paddle agitates the clothes in the soapy water. When it comes to spin, holes in the drum let the water out. So, if you need a big force quickly, a centrifuge is a really handy way to generate one. Since the spinning happens on the spot, there is not much space required. That makes it perfect for use in scientific laboratories. One of its most common use is separating substances of greater and lesser density.
Laboratory centrifuges are used to separate things like blood, plasma and serum. They are of different types like micro centrifuges, clinical centrifuges, high speed centrifuges, ultracentrifuges etc. Ultracentrifugation is a process involving spinning the rotors under vacuum, eliminating air resistance and enabling exact temperature control. Ultracentrifuges can be preparatory or analytic.
Because of the heat generated by air friction, many types of laboratory centrifuges are refrigerated and temperature generated. The refrigerated centrifuges have refrigerated rotor chambers and are used to collect substances that sediment rapidly. The centrifuge tubes are precision-made, high strength tubes of glass or plastic made to fixed exactly in rotor cavity. A micro centrifuge is an important lab equipment that is used to spin small liquid samples at high speeds. Features to look for include programmable controls, rotor size, capacity, speed and quiet operation.
Centrifugal filters are porous or have perforations and are rapidly rotated to drive off liquid by centrifugal action.
Precautionary Measures with Centrifuges
Centrifuge machines can be very dangerous if not properly used and maintained. Manufactures should ensure effective lid locks. They should have imbalance detectors, over speed detectors and ability to contain any failure of rotor. Access to the rotor chamber should be avoided when the spin is in process. Care should be taken when you buy centrifuges machine online to ensure that the moving rotor is not touched and the long hair and clothing does not get caught in any rotating part. This is especially important for older centrifuges where lid can be opened even before the rotor has stopped rotating.
Samples should be kept in air tight and leak-proof containers, when centrifuging hazardous materials like infectious virus, carcinogenic or radioactive materials, majorly in low speed non-refrigerated centrifuges, in which rotor temperature is controlled by air flow. This is done in order to get rid of any kind of aerosol formations which may arise from any kind of accidental spillage of sample, which would in turn result in contaminating the rotor, centrifuge and possibly the whole of the laboratory. Also, avoid cleaning plastic tubes in automated dishwashers, which may produce excessively hot temperatures. Get the best centrifuge machine price when you buy Laboratory Equipment online.
