Vivacon® 500 ETO Centrifugal Concentrator

Up to 500 µl starting volume
Concentrate up to 50x

Vivacon 500 ETO devices allow rapid concentration of DNA and PCR primer removal for samples up to 500 µl volume. Vivacon 500 ETO uses low binding Hydrosart® regenerated cellulose membranes positioned horizontally for optimal results in these applications. They can be used in micro-centrifuges with fixed angle rotors accepting 2.2 ml centrifuge tubes. The Vivacon 500 ETO also allows reverse spinning of your sample for simplified recovery. 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 human genomic DNA contamination. Tests were performed with a qPCR assay over 55 cycles with a verified detection limit of 2 pg.
