* Single (0.5 mL) /Double-sided (5 mL, 15 mL) vertical filter structure provides an effective filtration area of up to 9.7 cm²
* Both 15 mL and 50 mL centrifuge tubes feature support ribs that are tightly integrated with membranes, facilitating enhanced structural stability and preventing membrane clogging or rupture under excessive centrifugal force
* Rapidly concentrates samples in 5–25 minutes, achieving a concentration factor exceeding 100-fold
* Minimal void volume, reduces sample loss during centrifugation
* Over 85% of protein recovery rate with excellent repeatability
* Precise black graduations on the tube body with clear MWCO indicators, and writing area for easy marking
*Membranes are secured into the filter shell using heat-pressing processes, without chemical leaching from adhesives that could contaminate samples and impact analysis results
