Sartorius VN02H82 Vivacon 2, 125,000 MWCO Hydrosart

Vivacon 2 are centrifugal units for fast DNA concentration and buffer exchange of 2 ml samples. They are also the product of choice for protein fractionation applications. The use of Hydrosart ultrafiltration membranes results in high recoveries from dilute samples. Complete recovery of the concentrate is guaranteed by a reverse spinning step. Vivacon 2 is optimized for the concentration / recovery and buffer exchange applications of genomic DNA and peptides for samples up to 2 ml initial volume. They are also the product of choice for peptide fractionation applications in this volume range. For optimal performance with highly diluted samples, e.g. forensic specimens, Vivacon 2 is equipped with patented Hydrosart regenerated cellulose membranes with extremely low unspecific binding properties and high flux. They have been treated with a dual-cycle ethylene oxide (ETO) gas process to ensure they are sterile to a safety assurance level of 106 and free of detectable genomic DNA contamination. Tests were performed with a qPCR assay over 55 cycles with a verified detection limit of 2 pg.
