Vivaflow® 50R

Vivaflow^® 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 breeding 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 50 cm² 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 final 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.

Equipment required

The standard Vivaflow^® 50R 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).
