Vivaflow® 200 is a ready to use and reusable laboratory crossflow cassette for concentrating up to 5 l samples. The membrane surface per device is 200 cm2. One unit comes with all necessary accessories for running the device with a laboratory pump and a size 16 pump head. For speeding up the concentration, two cassettes can be run simultaneously.
Vivaflow® 200 is optimally suited for applications like cell culture supernatant concentration, virus concentration and water concentration e.g. in 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 200 cm2 module typically concentrates 1 l by a factor of 50 in less than 30 min. Alternatively, two Vivaflow® 200 modules can be used in parallel for concentration of 5 l in under 75 minutes. Near total recovery of the concentrate is achieved with a single final rinse. Vivaflow® 200 can be easily 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® 200 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).

Running 2 Vivaflow® 200 cassettes in parallel
For speeding up the concentration, two Vivaflow® 200 cassettes can easily be connected using a Y connector which is preassembeled with the correct tubing sizes and fittings (size 16 tubing for connecting the two Vivaflow® 200 units, size 15 tubing for the pump). Please note that you need a size 15 pump head for running 2 Vivaflows® in parallel.
