Vivaflow 200 reusable laboratory crossflow cassette From Sartorius Stedim Biotech

 

New, Unused, from a Lab Clearance, still in Manufacturers packaging. Half Price £145.00 Each

We also have Masterflex pumps with EasyLoad 2 and Easy Load LS Heads. Which are needed to set up the system.

 

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 simultaniously.

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 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 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 required

The 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).
Running 2 Vivaflow 200 cassettes in parallel

For speeding up the concentration, two Vivaflow 200 cassettes can easily be connected using a Y connector which is preassembeled with the correct tubing sizes and fittings (size 16 tubing for connecting the two Vivaflow 200 units, size 15 tubing for the pump). Please note that you need a size 15 pump head for running 2 Vivaflows in parallel.
