Disposable and reusable ultrafiltration (UF) columns from Sterlitech can easily concentrate, separate, or purify samples in the ultrafiltration range using positive pressure. The disposable units are available in 10K, 50K and 200K cut-offs. They also feature a clear filtration chamber to visually monitor the filtration process.
Our reusable unit performs a similar function using a centrifuge method and a 13 mm filter diameter to easily collect the concentrated sample solution, the filtrate, or both (13 mm filter sold separately). Consult our UF Flat Sheet Membrane section to select the corresponding membrane for your application.
