Beskrivelse
Kombinerer høj hastighed med overlegen retentatgenvinding for at koncentrere meget fortyndede opløsninger. Sartorius Vivaspin™ 2 Centrifugalkoncentratorer: PES-membranen har dobbelte lodrette membraner, små indre overfladeområder og tynde kanaler. Fås i en række MWCO- og emballagemængder.
Vivaspin concentrators are disposable ultrafiltration devices for concentrating biological samples. Vivaspin 2 is designed for use with samples from 500μl to 2mL in rotors that accept 15mL centrifuge tubes. The unique design provides high-speed concentrations for even particle-laden solutions and near-total concentrate recovery.
Twin vertical membranes and optimal design for fast, safe concentration
- Patented twin vertical membrane design for ultra-fast processing speeds
- In a single spin, solution volumes up to 4mL can be concentrated up to 30x in 5-30 minutes
- Thin-channel filtration chamber minimizes membrane fouling and increases filtration speed
- Dead stop pocket built into the bottom eliminates the risk of sample filtration to dryness
- High-flux PES membranes feature very low protein binding and low extractables
Designed for maximum flexibility and sample recovery
- Low internal surface and membrane area for superior recoveries from very dilute solutions
- Two methods for easy concentrate recovery:
- Directly pipet the concentrate from the dead stop pocket in the concentrator
- Reverse-spin the concentrate into the recovery cap, which can be sealed for storage
- Both methods provide near-total concentrate recovery of greater than 90%
- Volume graduation for easy monitoring of concentrate volume and 8μl dead-stop volume
- Universal compatibility with swing bucket or fixed angle rotors accepting 15mL centrifuge tubes
