Sartorius Vivaspin™ Filtrate Centrifugal Concentrators

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
