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 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 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.
The standard Vivaflow® 50 package comes with two cassettes, tubing, flow restrictor, one series interconnector 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 more than two Vivaflow® 50 devices in parallel and series
For speeding up the concentration, as many as six Vivaflow® 50 cassettes can easily be connected using 2 T-connectors for connecting 2 Vivaflow® cassettes at the inlet and at the outlet and series interconnectors for connecting the devices inbetween. A pressure indicator needs to be built in the inlet for optimal control.
High flow rate and recovery
Clear housing for process monitoring
Ready to use single cassettes
Easy set up of multiple cassettes
Economical and disposable product
Unique in its performance
A single 50cm2 module will typically reduce 500 ml to less than 15 ml in under 50 minutes. Less than 10 ml minimum system recirculation for highest concentrations. Less than 1.5 ml non recoverable hold up volume. Near total recoveries achievable with a single 10 ml rinse.
