Since more than five years ago, all of Beckman Coulter's high-speed centrifuges have come standard with the company's patented Friction Reduction System (FRS). Because of the Beckman Coulter FRS, traditional high-speed centrifuges have seen significant improvements in terms of both their capacity and their efficiency. Due to the implementation of this technology, Beckman Coulter is now in the position to use rotors that have improved centrifugal power and capacity, faster acceleration, longer centrifuge drive life, better temperature control, and lower operating costs. The Comprehensive Capital Analysis and ReviewA powerful vacuum pump is an essential element of the FRS (Figure 2). This pump removes air from the centrifuge chamber as the rotor rotates, thereby lowering the internal pressure to a level that is one-fourth that of the pressure in the surrounding atmosphere. The overall dependability of the centrifuge has been improved as a result of the FRS, which helps reduce the strain that is placed on the centrifuge's motor as well as the cooling systems. The amount of friction and inherent drag caused by the spinning system is significantly reduced as a further benefit of removing some of the surrounding atmosphere from the chamber. Because of this, the total amount of heat that is produced is reduced, and an energy-efficient driving mechanism is produced as a result.
Increased amounts of force exerted by the centrifugal fieldThe power of the motor, the weight and shape of the rotor, the amount of resistance caused by friction caused by the mechanics of the rotor, and the amount of resistance caused by wind are some of the factors that determine the maximum acceleration that a centrifuge is capable of achieving. The utilization of FRS leads to a reduction in the frictional force brought on by air drag, which in turn results in an increase in centrifugal acceleration. Because of this, it is a lot easier to get the centrifuge up to its optimum speed and keep it there than vacuum dryer would be otherwise. Improved temperature controlWhen it comes to rotors that have large surface areas, like those found in the High-Performance Series, employing a method that reduces friction is beneficial for improving temperature control because it lowers the amount of heat generated by the rotor. We will use the rotor JA-14.50 as an example to demonstrate the benefits that come along with utilizing FRS. This will be done in order to illustrate our point.
The rotor is rotating at its maximum speed of 14,000 revolutions per minute and its surface velocity is approximately 845 kilometers per hour (about 525 miles per hour) when it is located at the point in the tube cavity that is furthest from the axis of rotation. When moving at extremely high speeds, there is a significant increase in the amount of friction that occurs, which in turn results in an increase in the amount of heat that is produced. The amount of friction that contributes to wind resistance is reduced as a result of the environment being more contained, which has the effect of reducing the amount of wind resistance. Without FRS, it is difficult to maintain a constant temperature in a centrifuge because the device has difficulty balancing large temperature changes. This makes it difficult to maintain a constant temperature in a centrifuge. Because of this, it is going to be difficult to keep the temperature stable. In addition to that, we require compressors that are noticeably larger and more powerful than those that are currently available. Permanent centrifugeThe Beckman Coulter centrifuges are built to last for a significant amount of time and use. Because of the more controlled environment that the FRS provides, the refrigeration compressor, drive system, and rotors are all expected to have a longer lifespan.
increased efficiency in the process of energy conservationA quarter of an atmosphere is the operating pressure for Avanti JXN centrifuges. This results in an additional reduction in the amount of heat generated by friction as well as the resistance to wind. Even though it is working at a pressure that is only a quarter of an atmosphere, the rotor is able to maintain the speed that has been set for it. The operation of the vacuum pump stops as soon as the desired level of pressure is reached within the space being pumped. The FRS will not start operating the vacuum pump again until there is a loss in the system, which will signal that additional vacuum is required. Once this occurs, the FRS will begin to function as a smart system. As a consequence of this, the expenses related to the consumption of energy are decreased, and improved temperature control is accomplished. decreased operating costs on a global scaleThe Beckman Coulter centrifuge/rotor systems with FRS assist laboratories in lowering their costs by lowering maintenance requirements, extending the life of the centrifuge, and improving the centrifuge's energy efficiency.
Centrifuges have an easier time reaching and keeping their maximum speed because the revolving rotors experience a lower amount of frictional air resistance than other types of devices do. This makes it possible for centrifuges to process more material in a shorter amount of time. The instruments can be kept at a cooler temperature while still operating at a higher level of efficiency because the refrigeration compressor can use less energy to reach and maintain the required temperature in the rotor chamber. This allows for the instruments to be more effective. In laboratories, it is not uncommon to find an abundance of equipment that generates an excessive amount of heat, such as freezers, refrigerators, and other pieces of machinery. This is due to the nature of the work that is performed there. Because there is less heat being generated, the environment of the laboratory can be preserved with fewer resources and at a lower cost. This is possible because the amount of heat being generated has decreased. As a result of this, the laboratory has less of an effect on the environment around it, its expenses as a whole are reduced, and the lifespan of the equipment is increased.
a heightened sense of safety and protectionA higher level of laboratory safety is achieved by utilizing FRS in Beckman Coulter centrifuges, which is one of the most significant advantages of using FRS in these machines. Because the vast majority of researchers work with radioactive or biohazardous materials, the Avanti JXN's centrifuge chamber generates a partial vacuum, which allows for the installation of a pharmaceutical-grade sterilizing filtration system in the space that exists between the vacuum pump and the rotor chamber. This filter is designed to collect potentially hazardous particles, such as pathogens and aerosols, in the event that a bottle or tube is broken, preventing them from escaping into the surrounding environment. It is possible to make the workers in the laboratory more secure by lowering the concentration of sample fumes that they are exposed to. In addition to this, the FRS improves mechanical safety because it enables an evaluation of the compatibility and safety of rotors by employing wind resistance as a measurement, which in turn makes this evaluation possible. It would be difficult to make this assessment if one did not know the pressure inside the rotor chamber. This could lead to catastrophic damage and the collapse of the rotor if one did not know the pressure.
