Sartorius VS0142 VivaspinŽ 500. 100.000 MWCO PES. 100pc

pVivaspinŽ centrifugal concentrators are disposable ultrafiltration devices for the concentration of biological samples. VivaspinŽ 500 centrifugal filter units offer a simple, one step procedure for sample concentration with starting volumes up to 500 l. They can effectively be used in fixed angle rotors accepting 2.2 ml centrifuge tubes. The patented vertical membrane design and thin channel filtration chamber (US 5,647,990), minimises membrane fouling and provides high speed concentrations. VivaspinŽ 500 units are available with PES membrane in a wide range of molecular weight cut-offs. Concentrate recoveries of 90% can be reached in less than 30 min. The dead stop pocket prevents concentration to dryness./p ulliHigh flux PES membrane/liliHigh retentate recovery 90 %/liliVertical membrane design for ultra fast concentration/liliUniversal rotor compatibility/liliSafe sample concentration due to dead-stop volume/liliConvenient concentrate recovery by pipetting/liliVolume graduation for easy reading/monitoring/li /ul h3VivaspinŽ 500 Polyethersulfone, 100 kDa/h3 h3Performance Characteristics/h3 !-- Table - VivaspinŽ 5002 -- tabletheadtr th scope="col"/th th scope="col" Time to concentrate up to 30x [min.] at 20°C/th th scope="col" Concentrate recovery %/th/tr/theadtbodytr td Start volume/td td 500 ?l/td td 500 ?l/td/trtr td colspan="3" Aprotinin 0.25 mg/ml (6,500 MW)/td/trtr td 3,000 MWCO PES/td td 30/td td 96 %/td/trtr td colspan="3" BSA 1.0 mg/ml (66,000 MW)/td/trtr td 5,000 MWCO PES/td td 15/td td 96 %/td/trtr td 10,000 MWCO PES/td td 5/td td 96 %/td/trtr td 30,000 MWCO PES/td td 5/td td 95 %/td/trtr td colspan="3" IgG 0.25 mg/ml (160,000 MW)/td/trtr td 30,000 MWCO PES/td td 10/td td 96 %/td/trtr td 50,000 MWCO PES/td td 10/td td 96 %/td/trtr td 100,000 MWCO PES/td td 10/td td 96 %/td/tr/tbody /table
