Vivaspin® centrifugal concentrators are disposable ultrafiltration units for the concentration of most macromolecules - including proteins
these devices are simply spun in a large capacity centrifuge (carriers accepting 250 mL bottles)
PES Vacuum Filtration Units includes the following materials: a polyethersulfone (PES) membrane filter
Designed specifically for research purposes and with user experience and daily workload in mind
Vivaspin® 100 can be pressurized on a laboratory benchtop or in a refrigerator
Vivaspin® 6 Centrifugal Concentrator Polyethersulfone, 25 pc cell culture filtration Vivaspin® centrifugal concentrators are disposableVivaspin 6 is suited for the concentration of most macromolecules, including antibodies, proteins, nanoparticles and viruses, from initial sample volumes up to 6 mL. The high performance twin PES membranes provide fast sample concentration and high recoveries. An integral low volume dead stop pocket enables more than 100 fold concentration factors while eliminating the risk of sample loss and simplifying retentate retreival. Volume graduations on the
