Vivacon 2, 30,000 MWCO Hydrosart, 500pc

100 µl - 2 ml
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.

Order Number:  VN02H23

Availability:  On Request

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. Selected MWCOs are available sterile and DNA free (PCR Grade units). 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.

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 peptide fractionation (Filter Aides Sample Preparation, FASP1). The possibility of a reverse spin after sample processing assures complete concentrate recovery which is especially important when working with low sample concentrations.
