PES Ultrafiltration Centrifugal Tube 50mL
Protein Concentration & Desalting Filter Tube

    ✔ 8 cut-off options | Hydrophilic PES | Low protein binding | OEM ready                   🔬 Product Overview
The PES Ultrafiltration Centrifugal Tube 50mL is a high-performance centrifugal filter device engineered for protein concentration, desalting, buffer exchange, and particle/microorganism             removal in life science, biopharma, and environmental labs. The hydrophilic PES (Polyethersulfone) membrane ensures low protein binding, broad chemical resistance, and outstanding mechanical strength.
        🎨 Color: Clear / Transparent — fully transparent tube wall allows easy visual monitoring of sample residual volume during centrifugation.
