Microfilter Vivaclear™

Overview Vivaclear™ centrifugal microfilters provide fast, small-volume clarification of biological samples. The 0.8 µm polyethersulfone (PES) membrane enables reliable particle and precipitate removal for downstream processing. Typical filtration of micro sample volumes (up to 0.5 mL) takes 2–10 minutes; the integrated cap allows immediate storage of the filtrate in the same collection tube.

Features

• 0.8 µm polyethersulfone (PES) membrane
• Integrated cap for sealing the filtrate tube for storage
• Typical filtration time: 2 to 10 minutes for micro sample volumes
• Spin column format compatible with standard fixed-angle rotors

Applications

• Clarification prior to ion-exchange purification
• Prefiltration of plasma and serum
• Sample clarification before concentration with Vivaspin® 500
• Removal of particles or precipitates
• Cell culture or lysate clean-up
