Vivacon 500 ETO

PCR Grade Vivacons achieved by Ethylene Oxide Treatment

The new Vivacon 500 PCR Grade units, in addition to all features described for Vivacon 500, have been treated with a dual-cycle ethylene oxide (ETO) gas process to ensure they are sterile to a safety assurance level of 10-6 and free of detectable human genomic DNA contamination tested by using a qPCR assay over 55 cycles with a verified limit of detection < 2 pg.

Vivacon 500 are centrifugal concentrators for the concentration of DNA or proteins and buffer exchange applications with samples up to 500 µl. For optimal performance with very dilute samples, e.g. forensic specimens, Vivacon 500 is equipped with the patented Hydrosart® regenerated cellulose membrane that guarantees extremely low binding properties and high flux. High recoveries and excellent reproducibility are paired with convenience offered by the molecular weight cut-off printed on individual devices.

Vivacon 500 features a horizontal membrane design that is preferred by some users for reasons of consistency with previously used procedures and high reproducibility. The possibility of a back-spin after sample processing assures complete concentrate recovery which is especially important when working with low sample concentrations.
