100mL Centrifugal Concentrator, PES Membrane, MWCO 3kDa, Non-sterile

Centrifugal concentrator is an upgrade of centrifugal ultrafiltration tube technology. Optimized for 20–90mL large-volume biological samples, equipped with vertical PES membranes for fast concentration and high activity preservation. Easy to operate without pipeline assembly, perfectly suited for proteins, nucleic acids, viruses and other large-volume biological samples. Widely used in biopharmaceuticals, protein research and molecular biology.

Features Operating Temperature: 0-40℃ pH Range: 1-12 Compatible Rotor: 250mL swinging bucket rotor Maximum Relative Centrifugal Force: 2000 × g Non-sterile Equipped with vertical PES ultrafiltration membrane, enabling 30–50 fold protein concentration. Fast flow rate with negligible protein damage; recovery＞85%, protein binding＜10μg/cm². No tubing assembly needed; concentration of 90mL sample takes as short as 30 min. Built-in stop-volume design prevents sample degradation from over-centrifugation. Various MWCO specifications are offered to suit separation of molecules with different molecular sizes.

User Guide Before use, it can be disinfected and sterilized by filtering 70% ethanol through the device. Storage: Before use: at room temperature in a cool place; After use: stored by moistening with 20% ethanol or pure water.
