Sartorius Ultrafiltration -

Concentrators Vivaspin

Applications:
• Concentration, purification and desalination of biological solutions: proteins, enzymes, antibodies, viruses, immunoglobulins
• Elimination of "primers" (PCR), amino acids, nucleotides
• Highest filtration surface enables excellent flow rates and quick concentrations to be obtained
• Low adsorbent materials and anti-drying out system for a maximum recovery rate
• Sloping membranes, single or double, parallel to the centrifugal force: no clogging, greater efficiency
• Highest concentration factor: between 120 and 400 times depending on the unit types
