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
