03 High retention rate

Effectively retain impurities and particles to ensure filtrate purity and the accuracy of experimental results.

04 High-quality materials

Syringe filters are made with high-quality polypropylene housing to ensure durability and robustness, enabling a longer lifespan and greater reliability during experiments.

05 Strong pressure resistance

Syringe filters are designed with high-pressure resistance, able to withstand high pressures without deforming or breaking, which maintains their integrity and filtration efficiency even in high-pressure filtration environments.

06 Low dissolution

High-quality materials and precise manufacturing processes ensure extremely low extractables. It is particularly important to avoid bringing in impurities during the filtration process for sensitive analytical experiments.

07 Double-layer syringe filters with pre-filtration

Syringe filters incorporate a pre-filtration feature, specifically designed for handling samples with high particle content. This effectively increases filtration efficiency and extends the filter membrane's lifespan, reducing resistance for challenging samples and enabling faster filtration.

08 High-throughput Filter Plates

Designed for high-throughput sample processing, the High Throughput Filter Plate is available with 24/96 wells to filter 24/96 samples at a time for improved filtration efficiency.

Copure^®Syringe Filters Performance Data

Flow rate data performance comparison: Ensure that the liquid maintains a consistent flow rate when passing through the filter, and avoid any influence on the filtering effect and the uniformity of the sample due to changes of the flow rate.


Method for testing the flow rate: Wet the filter with pure water or alcohol (ues pure water when using the NY, PES, Hydrophilic PTFE filters). Measure the volume of the corresponding liquid passing through under 10 psi for one minute.

Retention rate performance comparison：Effectively retain impurities and particles to ensure the purity of the filtrate and the accuracy of experimental results.


Selection of standard particle: 0.22 μm membrane filters are tested with 0.3 μm standard particles, and 0.45 μm membrane filters are tested with 0.46 μm standard particles.

Dissolution performance comparison：By following high-quality materials and precise manufacturing processes, the extractables of the syringe filter are extremely low. It's important for sensitive analytical experiments to ensure that no impurities are introduced during the filtering process to affect the accuracy of the experimental results.
