Vivaflow® 50R is a ready-to-use, reusable laboratory crossflow cassette for concentrating samples up to 1 L. Ideally suited for applications such as cell culture supernatant concentration, virus concentration, and water sample concentration, for example environmental samples or water from fish farming facilities, this economical product offers an unmatched standard of ease of use, reliability, and flexibility compared with any laboratory filtration system on the market.
The modules’ thin-channel, reverse-flow recirculation path provides high crossflow rates with minimal pump speed requirements. A single module with 50 cm² active membrane area typically concentrates 250 mL by a factor of 20 in less than 30 minutes. Alternatively, two Vivaflow® 50R modules can be used in parallel to concentrate approximately 1 L in about 45 minutes.
Nearly complete recovery of the concentrate is achieved with a single final rinse. Vivaflow® 50R can be easily cleaned and reused several times.
All accessories required for sample concentration using a single cassette are included in the package, except for the peristaltic pump with a size 16 pump head. For fast and convenient buffer exchange, a closed 500 mL diafiltration reservoir can be added to the system.
