Vivaflow® 200 Laboratory Cross Flow Cassette

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 requiredThe 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).Equipment requiredThe standard Vivaflow^® 200 package comes with tubing, pressure indicator, flow restrictor and high pressure pump tubing.
