Vivaspin® Filtrate is a ready-to-use centrifugal ultrafilter that is ideal for isolating small drug molecules, hormones and metabolites for analytical results you can rely on. A broad range of molecular weight cut-offs (MWCOs) ensures suitability to effectively remove a broad range of proteins and nanoparticles from your sample. Furthermore, ultrafiltration in the opposite direction to centrifugal force (counterflow ultrafiltration) supports rapid filtration of even very viscous or particle-loaded samples, while the filtrate can be collected directly by pipette, with no disassembly required.
