Centrifuges & Centrifuge Manufacturers
Centrifuges use accelerated centrifugal force to effectively separate particles from solutions according to their size, shape, density and viscosity. The uses and applications of centrifuges permeate industrial, commercial and even residential settings. From medicines and fuel to groceries and laundry, centrifuge use is dynamic and diverse.
Capable of creating forces up to twenty thousand times that of normal gravity, centrifugal separators are essential to both isolating suspensions and isotope separating. Basket centrifuges accomplish this by containing materials in an enclosed space that is fixed around a constant axis. Spinning the suspensions and solutions at high speeds around this central point increases the pull of gravity causing denser particulates to separate out first creating layers of materials based on specific gravities. Beyond separation industrial centrifuges are used for product washing, extraction and purification. Laboratory centrifuges perform the same functions on a much smaller scale and are often implicated in both preparative and analytical contexts. Both applications often utilize high speed centrifuges or ultracentrifuges which allow for faster sorting and accumulation of elements. While batch operations are more common to laboratory centrifuge use, industrial mechanisms such as gas centrifuges and oil centrifuges are often continuously run to allow for increased productivity. Decanter centrifuges utilized in water treatment applications are likewise used in continuous operation to accommodate large facility and city water supply. For both batch and continuous centrifuges balance is an important consideration as even slight imbalances will throw off the equilibrium of the spinning cycle inflicting unnecessary and potentially dangerous stresses on the device. This should be considered when purchasing new or used centrifuges. Manufacturers and retail associates can help consumers determine the necessary centrifuge requirements for a given application.

Centrifuges can be used in industrial, commercial and residential settings. They are used to separate particles from solutions based on their size, shape, density and viscosity. Aerospace, medical, chemical, seismology, biotechnical and other research or explorative industries and applications utilize the unique properties of centrifuge operation to study everything from astronaut and pilot physiology under extreme conditions to virus and serum analysis in controlled environments. More accessible applications include the use of these mechanisms in washers and dryers to extract not only water, but dirt and debris as well. Many food and beverage processing industries also utilize the purification and degumming capabilities of centrifuges in the production of wine, beverages, edible oil products such as olive oil and dairy products such as cheese, milk and cream. Gas centrifuges in particular are used to enrich uranium for the production of nuclear energy. These devices are carefully monitored by several national and international agencies as they provide the possibility for nuclear weaponry. Pharmaceutical, agriculture and textile industries also utilize centrifuges to varying degrees in both daily and specialized operations. Centrifuges do not follow the idea that one size fits all because they are not mass produced and come in many different shapes, sizes and uses and are selected for a single and known application. With uses abound, the size and degree of force that a specific device can exert will help to determine its applicability and usage.
In any of these applications the basic function of the centrifuge remains relatively the same. An enclosure or arm-like apparatus is attached to a fixed central axis about which it can move in rotary motion. Often made of metal or plastic, this is what holds the items or materials to be isolated, analyzed or tested. Industrial centrifuges have a large cavity for materials while laboratory capacities are much smaller. Many small or micro-centrifuges hold several vials in order to process multiple samples at once. In some applications the solutions and suspensions are secured and in place prior to rotation while others require they be introduced during acceleration. An attached motor facilitates spinning. Force is applied to the axis perpendicular to the central axis in order to promote circular motion. This movement creates what is known as centrifugal force. The acceleration rather than speed is the integral consideration as centrifuges with different diameters will have variable acceleration even at the same speeds. At high enough acceleration the rotational pull causes more dense substances to separate out first in a radial direction. Heavier particles collect around the walls or the bottom of the device while lighter particles move up. This accelerated force can be used to augment normal gravitational pull to cause layered sedimentation based on mass or in the case of screening centrifuges drive the materials through a filtration sieve in order to facilitate particulate separation.
Centrifuges may be categorized by style of design as well as purpose. By purpose, there are two types of centrifuges: preparative and analytical. The former encompasses all those devices designed to sort or isolate specific particles or materials from slurries or liquids. Differential models separate particles from slurries or other particulates while density centrifuges separate types of fluid. Analytical centrifuges are more commonly used for inquisitive or research based applications as they measure the physical properties of a suspension or solution. Common data procured include molecular weight, sedimentation coefficients and macromolecular behavior. Designs are far more variable than purpose. Basket models are popular as are bowl models which may be classified as tubular or chamber types. Tubular bowl centrifuges use a tube-like enclosure that is much longer than it is wide. Chamber centrifuges are similar but use a series of bowls to progressively sort sediment. In addition to design and purpose, the acceleration or speeds a given centrifuge is capable of achieving are also important to consider. Acceleration is measured in G or gravitational force while speed is measured in RPMs or revolutions per minute. Additional application specific considerations include particulate size, sorting needs, slurry density, material viscosity and overall size. Centrifuge operation is relatively simple to understand on a basic level, though the complex physics of the devices should be carefully understood before use.
