Vivaflow 50 is a disposable and ready-to-use crossflow cassette for filtration and concentration of samples from 100 ml to 3 l. The membrane surface per device is 50 cm². One pack contains two devices and comes with all necessary accessories for running two devices with a laboratory pump and a size 16 pump head. For speeding up the concentration and increasing the volume throughput, six cassettes can be connected.   
   
Optimally suited for applications like cell culture supernatant concentration, virus concentration and water concentration e.g. in fish breading 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 50 cm² module typically reduces 500 ml to 15 ml in less than 50 min. Nearly total recovery of the concentrate is achieved with a single rinse. Up to six of the unique interlocking modules can be connected for easy scale up resulting in a capacity of several liters. Vivaflow 50 is intended for single use. All accessories for sample concentration, except a peristaltic pump with a pump head for size 16 tubing, are included in the package. A 500 ml sealed diafiltration reservoir can be added to the system for rapid and convenient buffer exchange.
