The COBETTER Ultra Centrifugal Filter 15mL ultrafiltration tube features a regenerated cellulose (RC) membrane with a 3kDa cutoff, enabling rapid concentration (80-100x) of proteins and biomolecules within 10-60 minutes. Designed for both fixed angle and swing bucket rotors, it delivers over 90% protein recovery with minimal adsorption. Its durable construction and optimized membrane area (7.4cm²) make it ideal for protein purification, buffer exchange, and biomolecule isolation in professional lab settings.
