Ultrafiltration
Vivacon 2 PCR Grade
The Vivacon 2 PCR Grade units 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 human genomic DNA contamination. Tests were performed with a qPCR assay over 55 cycles with a verified detection limit of 2 pg.
Vivacon 2 are centrifugal devices for DNA concentration and buffer exchange applications for samples up to 2 ml. They are also the product of choice for protein fractionation applications. For optimal performance with very dilute samples, e.g. forensic specimens, Vivacon 2 is equipped with patented Hydrosart® regenerated cellulose membranes with extremely low unspecific binding properties and high flux. High recoveries and excellent reproducibility are paired with convenience offered by volume graduation and molecular weight cut-offs printed on individual devices. Vivacon 2 features a horizontal membrane design optimal for DNA fractionation (primer removal) as well as protein fractionation (peptide removal). The possibility of a reverse spin after sample processing assures complete concentrate recovery which is especially important when working with low sample concentrations.
