Sartorius VF05P9 VivaflowŽ 50. 3.000 MWCO PES. 2pc

pVivaflowŽ 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 cm˛. 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./p pOptimally 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 cm˛ 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. VivaflowŽ 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./p h3Equipment required/h3 pThe standard VivaflowŽ 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)./p h3Running more than two VivaflowŽ 50 devices in parallel and series/h3 pFor speeding up the concentration, as many as six VivaflowŽ 50 cassettes can easily be connected using 2 T-connectors for connecting 2 VivaflowŽ 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./p ulliHigh flow rate and recovery/liliClear housing for process monitoring/liliReady to use single cassettes/liliEasy set up of multiple cassettes/liliEconomical and disposable product/li /ul h3Unique in its performance/h3 pA single 50cm˛ module will typically reduce 500 ml to less than 15 ml in under 50 minutes.
