• For scientists and lab technicians who need to quickly and safely concentrate biological samples of 4ml to 15ml up to 150-fold.
• Can handle up to 15ml sample volume in swing bucket rotors and 11ml in fixed angle rotors accepting 50ml centrifuge tubes.
• Ultra-filtration is a non-denaturing method that is more efficient, flexible and gentle than alternative processes.
• In a single spin, 15ml solutions can be concentrated up to 150X.
• The fastest sample concentration with highest recoveries.
• Offers the optimal solution to any concentration or buffer exchange application with its broad range of MWCO’s.
• Applications include sample concentration (protein, lipid, virus, nanoparticle, macromolecule), desalting/dialysis and rebuffering.
• Highest flow rates are achieved due to their twin vertical membranes which minimize protein polarization and subsequent fouling of the membrane.
• Sleek internal profile ensures maximum process speeds right down to the last 100µl.
• Samples can be typically concentrated in 10 to 30 minutes with macromolecular recoveries in excess of 95%.
• Polyethersulfone membranes are preferred for their low fouling characteristics, exceptional flux and broad pH range compatibility.
• Centrifugation provides the vector to clear solvent and micro molecules through an ultra-filtration membrane to separate macro-molecular species and solvents primarily on the basis of size.
• Particularly appropriate for the concentration of macromolecules. Can also be used to purify molecular species or for solvent exchange.
• The UV joining technology allows for a smooth joint transition between membrane and plastic housing, allowing the sample to be collected into the unique pipette-friendly dead-stop pocket. The 100µl dead stop pocket is easy to access with standard 200µl pipette tips.
• It eliminates the risk of the sample running to dryness while allowing highest recovery of the concentrate.
• The combination of polyethersulfone (PES), polystyrene and polypropylene (PP) allows sterilization and depyrogenization.
• Universal rotor compatibility.
• Volume graduation for easy detection/monitoring of the concentrate volume.
• Made of styrene butadiene copolymer, with a polypropylene filtrate vessel, polypropylene concentrator cap and polyethersulfone (PES) membrane.
• Dimensions: Total length (concentrator insert) 77mm; Total length (in tube with cap) 118mm; Diameter (concentrator insert) 27mm.
• Active membrane area: 7.2cm2.
• Hold up volume of membrane: <10µl.
• Dead stop volume in swing out: 100µl.
• Dead stop volume in fixed angle: 60µl.
• Maximum speed: 4000 x g.
• Sterilization: ETO or 70% EtOH.


NOTE: Vivaspin® Turbo 15 (30mm x 118mm) is designed to fit into rotors that can accommodate Falcon 50ml conical bottom tubes. These devices are not designed to fit into rotors that only accept round bottom 29mm x 105mm tubes. If your rotor accepts only 29mm x 105mm round bottom tubes, please use the Vivaspin® 15, which can be used in either round bottom or conical centrifuge tubes.
