Vivaspin® Turbo 4 can handle up to 4 ml sample volume in 4 swing-out and fixed angle rotors accepting 15 ml centrifuge tubes. The Vivaspin® Turbo 4 optimised design, the sleek internal profile, ensures maximum process speeds right the way down to the last few micro litres after > 100 fold concentration. The UV joining technology allows for a smooth joint transition between membrane and plastic housing, allowing the collection of the complete concentrated sample into the unique pipette friendly dead stop pocket. Sleek internal design as well as large vertical twin membranes for ultra fast concentration High retentate recovery > 95 % x pH 1-14 suited polystyrene housing with high chemical compatibility High flux PES membrane Universal rotor compatibility Safe sample concentration and easy recovery due to unique, angular and pipette friendly dead-stop pocket Volume graduation for easy detection / monitoring of the concentrate volume > 100-fold concentration with twin vertical membranes Performance Characteristics
