Vivaspin® Centrifugal Concentrators

Vivaspin centrifugal concentrators offer the most comprehensive range of devices with initial sample volumes from 0.1 to 20 mL. They are available in MWCO's ranging from 2 to 1,000 kDa to provide optimal solutions for any ultrafiltration or buffer exchange application. Integrated dead-stops ensure the highest concentration factors while avoiding sample loss through concentration to dryness. There is no safer or easier way to concentrate, desalt or re-buffer your target molecule. These devices are used for a variety of applications by clinical diagnostic and biotech labs. Vivaproducts also provides centrifuges for use with these filters.

Urine Protein Concentration Calculations

This calculations app provides a table of concentration factors (CF) for your urine electrophoresis samples. It assumes that you first measure your sample Total Protein and then desire to adjust the CF accordingly.
