Vivaspin 20 Centrifugal Concentrator, 100 kDa MWCO, 12/PK, Sartorius, VS2041

Sartorius® Vivaspin® 20 Centrifugal Concentrator, 100 kDa MWCO, 12/PK, VS2041

Features:

• Increased volume flexibility and performance
• Handles up to 20 mL in swing bucket rotors and 14 mL in fixed angle rotors accepting 50 mL centrifuge tubes
• Twin vertical membranes for unparalleled filtration speed and >100-fold concentration
• Volume graduation allows easy reading/monitoring of concentration process
• Modified dead stop pocket simplifies pipetting of final concentrate
• Available with unique accessories and operating methods—for one-step desalting following concentration, diafiltration cup filled with buffer is placed on concentrator and spun to achieve 98% salt removal, instead of two spins to achieve same result as traditional refill and re-spin procedure
• Single sample processing, for gas pressure filtration, Vivaspin™ 20 can be filled with up to 15 ml and then pressurized for bench top concentration
• For even faster processing, gas pressure filtration can be combined with centrifugation—pressure-fugation is particularly useful for difficult or viscous samples such as serum, when using low process temperature, or generally when minimum process time is essential
• High flux PES membrane
• High retentate recovery > 90 %
