The Vivaflow Range of Tangential Flow Concentrators
for Volumes from 500 ml to over 5 Liters
Ultrafiltration and Cell Harvesting Filtration
Vivaflow 50
The novel Vivaflow system (patents pending)
standardly provides of ease of use, performance,
flexibility and economy which is
unrivalled by any laboratory or pilot scale
filtration system on the market.
Thin channel flip-flow recirculation path
provides high cross flow velocities with
minimum pump requirements. Unique
interlocking modules with series connectors
make it easy scale up.
A single 50 cm 2 module will typically reduce
500 ml to less than 15 ml in under 50 minutes.
Less than 500 µl of non-recoverable
hold up volume remains.
Vivaflow 200
Concentrate 250 ml to under 20 ml in just a
few minutes or concentrate one liter 50 times
in less than 30 minutes. Alternatively, use
two Vivaflow 200 parallel to one another and
concentrate 5 liters in under 75 minutes.
Near total sample recoveries can be expected
with most solutions. Desalting or buffer
exchange is just as quick when using the
optional recirculation assembly available
from Vivascience.
The economical standard package comes
complete with tubing, pressure control gauge,
flow restrictor and high pressure pump tubing.
All you need is a peristaltic pump capable
of handling 6.4 mm OD (size 16) tubing.
