Vivacon® 2 centrifugal concentrators offer the optimal solution for DNA and protein concentration and buffer exchange applications. For optimal performance with very dilute samples, e. g. forensic samples, Vivacon® 2 is equipped with the patented regenerated cellulose membrane Hydrosart®. High recoveries and excellent reproducibilities are paired with convenience offered by volume graduation and molecular weight cut-off printed on individual devices. The possibility of a re-spin after sample processing assures complete concentrate recovery which is especially important when working with low sample concentrations.
