Description

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
