Description
Viva is a ready-to-use and reusable laboratory crossflow cassette for
concentrating up to 1 l samples. Optimally suited for applications like
cell culture supernatant concentration, virus concentration and water sample conc
(e.g. environmental samples or water from 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 module with 50 cm2 active membrane area typically
concentrates 250 ml by a factor of 20 in less than 30 min.
Alternatively, two Vivaflow® 50R modules can be used in parallel
for concentration of 1 l in approx. 45 minutes. Near total recovery of the
concentrate is achieved with a single final rinse.
Viva can easily be 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 Viva 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).
