Sartorius, VF05H0, Vivaflow 50R, 10000 Dalton MWCO Hydrosart Crossflow CassetteVivaflow 50R is a ready-to-use and reusable laboratory crossflow cassette for concentrating up to 1 l samples. Optimally suited for applications like cell culture supernatant concentration, virus concentration and water sample concentration (e.g. environmental samples or water from fish breading facilities), this economical product offers a standard of ease of use, reliability and flexibility unrivalled by any laboratory filtration system in the market.The thin-channel, flip-flow recirculation path of the modules provides high crossflow velocities with minimum pump speed requirements. A single module with 50cm² active membrane area typically concentrates 250 ml by a factor of 20 in less than 30 min. Alternatively, two Vivaflow 50R modules can be used in parallel for concentration of 1 l in approx. 45 minutes. Near total recovery of the concentrate is achieved with a single rinse. Vivaflow 50R can easily be cleaned and re-used several times.All accessories for sample concentration, except a peristaltic pump with a pump head for size 16 tubing, are included in the package for using a single cassette. A 500 ml sealed diafiltration reservoir can be added to the system for rapid and convenient buffer exchange.The standard Vivaflow package comes with tubing, pressure indicator, flow restrictor and high pressure pump tubing. All you need is a peristaltic pump with a pump head capable of handling 6.4 mm OD tubing (size 16).FeaturesPlug and play laboratory cross flow cassetteFast and easy protein sample concentrationReusableConcentrates volumes from 0.1 l -1 lOptimal for cell culture supernatant and virus concentrationSmallest cross flow cassette with premium Hydrosart® membraneHigh flow rate and recovery.
