Publish Time: 2025-06-25
In scientific research and industrial applications, a Large capacity benchtop low speed refrigerated centrifuge is ideal for processing large numbers of samples. This equipment not only meets the laboratory's demand for sample throughput, but also ensures sample integrity and separation results.
Temperature control and sample protection
Low temperature environments are critical for many biological samples, as they are easily damaged or denatured at room or high temperatures. The Large capacity benchtop low speed refrigerated centrifuge uses an advanced refrigeration system to maintain a stable low temperature during operation, usually in a temperature range of -20°C to +40°C. This precise temperature control helps prevent sample degradation or inactivation due to thermal damage, thereby ensuring sample integrity. In addition, some high-end models are equipped with a pre-cooling function that can pre-lower the temperature of the rotor before centrifugation, further reducing the time the sample is exposed to adverse temperature conditions.
Accurate speed regulation and balanced design
Speed regulation is one of the key factors to ensure sample integrity and achieve ideal separation results. Large capacity benchtop low speed refrigerated centrifuge allows users to precisely adjust the centrifugation speed (usually 1000 to 6000 rpm) according to different sample types and experimental needs. The appropriate centrifugation speed can not only effectively separate components of different densities, but also avoid the damage to the sample structure caused by shear force caused by excessive speed. In addition, these centrifuges also adopt a precision balanced design, which can maintain stable operation even in the case of uneven loading, reduce vibration and noise, and also reduce the risk of sample breakage.
Selection of rotors and centrifuge tubes
Correctly selecting the right rotor and centrifuge tube is essential to protect the integrity of the sample. Large capacity benchtop low speed refrigerated centrifuge provides a variety of rotor options, including fixed angle rotors, swing rotors, etc., each of which has its specific application scenarios. For example, fixed angle rotors are suitable for rapid precipitation of larger particles, while swing rotors are more suitable for fine separation of fine particles. At the same time, it is also important to choose the appropriate centrifuge tube material, common ones are polypropylene, polycarbonate, etc., which have good chemical stability and mechanical strength, and can withstand pressure changes during centrifugation without damage.
Intelligent control system and automated process
Modern large capacity benchtop low speed refrigerated centrifuge is equipped with intelligent control system, which allows users to easily set parameters such as temperature, speed, time and acceleration and deceleration rate through touch screen interface. The intelligent operation interface allows experimenters to focus more on the experiment itself rather than the complex operation of the equipment. What's more, some models support programming function, allowing users to create custom programs to suit specific experimental needs. In addition, the automated acceleration and deceleration function can be optimized according to the characteristics of the sample, reducing the possibility of sudden impact on the sample, thereby better protecting the sample.
The importance of maintenance and care
In order to maintain the best performance of the centrifuge for a long time and ensure the safety of the sample, regular maintenance and care are essential. This includes cleaning the internal and external components, checking the status of the seals, and lubricating the moving parts. Regular calibration is also a key step to ensure measurement accuracy and equipment reliability. Following the maintenance guidelines provided by the manufacturer can help extend the life of the equipment, reduce the occurrence of failures, and ultimately ensure that every experiment goes smoothly.
In summary, by properly using the various technical features of the Large capacity benchtop low speed refrigerated centrifuge, such as precise temperature control, appropriate speed regulation, correct rotor and centrifuge tube selection, and intelligent operating system, efficient separation can be achieved while ensuring sample integrity. This is of great significance for improving the accuracy of experimental results and promoting the development of scientific research. Whether it is biomedical research or food industry analysis, this centrifuge has demonstrated its irreplaceable value.
