Advantages of Centrifugal Filter Devices
Efficient Separation
Centrifugal filtration can quickly separate particles from liquids, making it ideal for time-sensitive applications.
High Throughput
It allows for processing large volumes of samples relatively quickly, making it suitable for both small-scale and large-scale applications.
Automated Process
Using centrifugal machines makes the filtration process easier to automate, reducing human labor and the potential for errors.
Improved Purity
By rapidly forcing the solid particles or microorganisms to the bottom of the filter, the technique can achieve high levels of purity in the filtrate.
No Chemical Additives
Unlike other methods that may require chemical additives or solvents, centrifugal filtration relies solely on mechanical forces, which is often a cleaner process.
Energy Efficiency
It typically uses less energy compared to some other separation methods like ultrafiltration or evaporation, especially for smaller or medium-scale applications.

Biological Sample Processing-Concentrating and purifying biological samples.
Concentrate proteins and nucleic acids from solvent.
Buffer exchange or desalting of chromatographic components.
Viruses isolotion and bio-molecule harvest in culture media.
Chemical Separation
Separate solid particles from liquid phases in chemical reaction mixtures.
Separate components with different molecular weights in solvent.
Industrial Filtration-food and beverage ,environmental protection
Removal of primers, adapters or molecular markers from the reaction mixture.
Steps for Using Centrifugal Filter Devices
Preparation-Rinse Before Use
Add 4mL pure water, deionized water or buffer solution to the ultrafiltration device.
Centrifuge at 4000xg (swing bucket) or 5000xg (fixed angle 45°) for 5-10 minutes.
Discard all liquids from the ultrafiltration unit and centrifuge tubes.
If any interference persists, wash with 0.1N NaOH under the same conditions as mentioned above, followed by rinsing 2-3 times with ultra-pure water, deionized water, or buffer.
Ensure that the ultrafiltration membrane remains wet once wetted until it is entirely used.
Add Sample
Carefully add your sample into the filter device, taking care not to overfill it (Fix-angle rotor centrifuge should add less volume as shown in Diagram 2 above). After adding the sample, securely seal the filter's lid to prevent any leaks during centrifugation.
Centrifugation
After loading your sample into the filter device, you should determine the appropriate centrifuge speed and duration based on the guidelines and specific properties of your sample.
Retrieve the Sample
Once the centrifugation process is finished, retrieve your samples from the filter. Avoid opening the lid while the rotor is still in motion, wait until the centrifuge rotor has slowed down or come to a complete stop.
