EV-Spinner is a 2.5 ml non-stick ultrafiltration (UF) concentrator to enhance the recovery of extracellular vesicle (EVs) during the concentration or buffer exchange step. The ultrafiltration works in the opposite direction to the centrifugal force, providing higher particle recovery. The low protein binding membrane (polyethersulphone) reduces the EV loss, compared to V-shape concetrators, and the reverse design of the EV-spinner ensures that the filter does not clog.
Applications: Concentration of solutions containing EVs, exosomes or nanoparticles. Concentration of diluted matrices as cell media or urine prior to EV isolation. Removal of small molecules and unbound dyes from solution containing EVs/exosomes and nanoparticles. EV and exosomes dialysis. Concentration of EV suspensions post SEC isolation.
Advantages: Non-stick, easy recovery of the retentate, washable, reusable multiple times.
