Vivaspin® Turbo 15 centrifugal concentrators by Sartorius Group

Vivaspin® Turbo 15 centrifugal concentrators offer the optimal solution to any concentration or buffer exchange application with their broad range of MWCOs.

Highest flow rates are achieved due to their twin vertical membranes which minimize protein polarization and subsequent fouling of the membrane. Additionally, their sleek internal profile ensures maximum process speeds right down to the last 100 μl.

Working Principle
Centrifugation provides the vector to clear solvent and micro molecules through an ultrafiltration membrane to separate macromolecular species and solvents primarily on the basis of size. It is particularly appropriate for the concentration of macromolecules and can also be used to purify molecular species or for solvent exchange. Ultrafiltration is a non denaturing method that is more efficient, flexible and gentle than alternative processes.

High Performance
In a single spin, 15 ml solutions can be concentrated up to 150x. Samples can be typically concentrated in 10–30 minutes with macromolecular recoveries in excess of 95%.

Optimized Design for Fastest Concentration Results
The Vivaspin® Turbo’s optimized design, its sleek internal profile, ensures maximum process speeds right the way down to the last few micro liters. The UV joining technology allows for a smooth joint transition between membrane and plastic housing, allowing all of your valuable sample to be collected into the unique pipette friendly dead stop pocket.

The ultimate in centrifugal ultrafiltration technology:
– Sleek internal design:
Ensures maximum process speed for
the complete filtration
 
– Large twin vertical membranes:
A fouling of the membrane is avoided due
to minimized protein polarization.

– Unique angular dead stop pocket:
The 100 μl dead stop pocket is easy to access with standard 200 μl pipette tips due to its patent pending angular design. It eliminates the risk of the sample running to dryness while allowing highest recovery of the concentrate.

Optimized Choice of Materials for High Chemical Compatibility
The combination of Polyethersulfone (PES), Polystyrene and Polypropylene (PP) allows sterilization
and depyrogenization of the Vivaspin® Turbo 15 units.

Polyethersulfone membranes are preferred for their low fouling characteristics, exceptional flux and broad pH range compatibility.

Applications
Sample preparation
– Sample (protein, lipid, virus, nanoparticle,
macromolecule) concentration
– Desalting | Dialysis
– Rebuffering

Your sample is often the result of several months of research. Your sample is valuable, and Vivaspin® Turbo 15 provides highest
recovery.

Summary
For scientists and lab technicians who need to quickly and safely concentrate biological samples of 4 ml to 15 ml up to 150 fold,
Sartorius offers the Vivaspin® Turbo 15 ultrafilters.

Unlike competitive ultrafiltration units, Vivaspin® Turbo 15 is equipped with an angular dead stop pocket, that enables reproducible and complete recoveries, while being the fastest in the market.
