0.5 to 5L and more
Vivaflow® 200 is a ready to use and reusable laboratory crossflow cassette for concentrating up to 5L samples. The membrane surface per device is 200cm2. 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 (such as in fish breeding facilities). This economical product offers a standard of ease of use, reliability, and flexibility unrivaled 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 200cm2 module typically concentrates 1L by a factor of 50 in less than 30 min. Alternatively, two Vivaflow® 200 modules can be used in parallel for concentration of 5L 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 500mL sealed diafiltration reservoir can be added to the system for rapid and convenient buffer exchange.
The standard Vivaflow® 200 package includes: tubing, pressure indicator, flow restrictor, and high pressure pump tubing. All you need is a peristaltic pump with a pump head capable of handling 6.4mm OD tubing (size 16).
