Vivacon® Centrifugal Concentrators
For High Recovery Concentration of Diluted DNA and Peptide Samples
Vivacon centrifugal units for DNA concentration and
buffer exchange are available for 500 μl to 2 ml initial
volume samples. They are also the product of choice
for peptide fractionation applications, like FASP*.
Selected cut offs are available sterile and DNA-free**
for DNA concentration and rebuffering applications
when even traces of DNA contamination are harmful.
The use of Hydrosart® membranes results in high
recoveries from even highly dilute samples.
Features & Benefits
Hydrosart® modified regenerated cellulose membrane
Membrane with lowest binding characteristics. Highest concentrate
recoveries, even when working with only ng amounts of sample, like
case work DNA.
Reverse spin possibility
Allows complete and reproducible concentrate recovery in a new
collection tube.
PCR Grade devices for DNA-free products**
Especially important in applications, when even traces of DNA are
harmful, like in forensic laboratories.
Horizontal membrane design
Ultrafiltration membranes in a horizontal configuration lead to
better results when concentrating extremely dilute DNA samples and
fractionating dilute samples.
Applications
– Genomic DNA concentration of e.g. forensic samples
– Peptide fractionation (FASP*)
– Primer removal
– Plasmid DNA concentrations / desalting
