Sartorius Vivaspin™ Filtrate Centrifugal Concentrators

Remove proteins from difficult to filter samples, even whole blood. Sartorius Vivaspin™ Filtrate performs centrifugal ultrafiltration against the direction of centrifugal force for fast and simple preparation of protein-free ultrafiltrates. PES and CTA membranes for 5000 to 300,000 Dalton MWCO.

Supplier:  Sartorius 13269E

Catalog No. 14-558-223

Description

Offered with multiple MWCOs and two membrane options:

• Cellulose triacetate (CTA) features high hydrophilicity and very low non-specific binding.
  • Cast without a support that could bind filtered solutes, these membranes are ideal where high target molecule recovery from the filtrate is important.
• Polyethersulfone (PES) membranes exhibit low fouling characteristics, exceptional flux and broad pH compatibility.
  • Have a uniform surface, devoid of hydrophobic or hydrophillic interactions, offering excellent protein recoveries for most solutions.
• Typical applications for Vivaspin™ Filtrate include:
  • Sample preparation for free drug
  • Metabolite or hormone analyses
  • Sample deproteinization
  • Separation of proteins from low molecular weight substances in biological samples
• Sample capacity of 0.5 to 2.5 mL
• May be used in fixed angle or swing bucket rotors, accepting standard conical or flat bottom 15 mL centrifuge tubes
• Typically filter 90% of the initial sample volume in 30 minutes
• Avoid premature membrane blockage by particle loaded samples
• Retrieve the ultrafiltrate immediately after centrifugation without any disassembly
