As a critical piece of equipment that leverages centrifugal force to achieve material separation, centrifuges are widely used across various fields—such as biomedicine, food processing, and environmental monitoring—thanks to their efficient and precise separation capabilities. Heng'er Biotech specializes in the research and development of tabletop centrifuges, offering high-speed and low-speed product lines that stand out for their compact footprint, user-friendly operation, and reliable separation performance. These features make them the preferred choice for laboratories and small-to-medium-sized production lines in diverse industries. Below, we’ll explore the application principles, equipment selection criteria, and tangible outcomes of Heng'er Biotech’s tabletop centrifuges through real-world cases in the biomedical field, highlighting their core value in specialized scenarios.

Food Processing Field: Juice Clarity Testing and Fine Impurity Separation

In the quality control phase of juice production, it is necessary to separate and detect tiny fruit pulp particles and pectin impurities in the juice to determine whether the product’s clarity meets the standard. At a juice-producing company’s laboratory, traditional filtration methods were previously used to measure juice turbidity, but these techniques failed to effectively remove fine impurities smaller than 5 μm in diameter. As a result, the test results often deviated significantly from the actual product quality, impacting production adjustment decisions. 

(1) Application Requirements and Challenges 
Companies need to test the clarity of products such as apple juice and orange juice, with a key indicator being turbidity no higher than 5 NTU. It’s essential to separate pulp particles and pectin impurities—measuring between 1 to 10 μm in diameter—from the juice. Each sample for testing should be 5–10 mL in volume, and laboratories are required to process 20–30 batches daily. The separation process must be quick (no more than 20 minutes) while preserving vital nutrients like vitamin C in the juice, ensuring that subsequent ingredient analyses remain unaffected. Additionally, given the high density of laboratory equipment, centrifugal devices used for this task must be compact, quiet, and designed to minimize interference with other ongoing experimental procedures. 

(2) Centrifuge Selection and Application Principles 
For your needs, we recommend the Heng'er Bio desktop high-speed centrifuge (Model: PRO2415). This device boasts a maximum speed of 15,060 rpm and can generate a centrifugal force of up to 21,300 × g. It is perfectly suited for use with 24 × 1.5/2.0 mL centrifuge tubes, features compact dimensions of 365 × 288 × 260 mm, and operates at a noise level of ≤60 dB—making it ideal for laboratory settings. Its powerful high-speed centrifugation capability ensures efficient separation of even the tiniest impurities, while the included rotor is crafted from aluminum alloy, providing uniform heat dissipation to prevent sample temperature increases. 
During the test, take a 10 mL juice sample and transfer it into a centrifuge tube. Place the tube into the device’s angular rotor, then set the centrifuge speed to 12,000 r/min and the centrifugation time to 18 minutes. Under high-speed rotation, the tiny fruit pulp particles (density of 1.08–1.10 g/cm³) in the juice, along with pectin impurities—since their density exceeds that of the juice (1.03–1.05 g/cm³)—are rapidly flung toward the bottom of the centrifuge tube, forming a fine sediment. Meanwhile, the upper layer remains as clear, filtered juice. After centrifugation is complete, carefully remove the upper layer of juice for turbidity testing. If the turbidity is ≤5 NTU, the product is deemed合格 (qualified). Additionally, the equipment features a program storage function, allowing users to save the centrifugation parameters used for juice analysis. This eliminates the need to reconfigure settings for subsequent tests, significantly improving operational efficiency. 

(3) Application Outcomes 
The application of Heng'er Biotech's benchtop high-speed centrifuge has boosted the accuracy of enterprise juice clarity testing from the original 85% to 99%, effectively preventing substandard products from reaching the market. Additionally, the time required for testing a single batch of samples has been reduced from the traditional filtration method’s 40 minutes to just 18 minutes, while daily testing capacity has increased from 20 batches to 35 batches—meeting the rapid quality-control demands of the production line. Moreover, the equipment operates with remarkable stability, maintaining a monthly failure rate below 1%, which significantly lowers maintenance costs. Its low-noise design also ensures a pleasant working environment in the laboratory, earning unanimous approval from testing personnel.
