Vivaproducts stocks a variety of concentrators and methods in sizes, MWCO's and materials to provide concentrations and purifications for many applications.
Centrifugal Filtration
100µl - 20 ml starting volume
Centrifugation provides the vector to clear solvent and micro molecules through the ultrafiltration membrane and into a filtrate container positioned below. This is a gentle process that is characterised by quick set up and fast filtration speeds with most solutions.
100 µl - 500 µl
One step procedure for small sample amounts
0.4 - 2 ml starting volume
Vivaproducts offers ten alternative centrifugal devices covering volumes from 0.4 ml up to 2 ml for fast and safe sample
1 - 4 ml
In a single spin, sample can be concentrated up to 200x
2 - 6 ml
Unique twin vertical membranes In a single spin, sample can be concentrated up to 100x
2 - 15 ml
Compatible with different collection tubes through narrow design In a single spin, 15 ml can be concentrated up to 300x
2 - 15 ml
Available with modified regenerated cellulose membrane; Hydrosat®
5 - 20 ml
Unique twin vertical membranes In a single spin, sample can be concentrated up to 400x
Pressure-Fugation
10 ml to 250 ml starting volume
Pressure-fugation is a unique Vivaproducts method that combines gas pressure with centrifugation. This is the fastest concentration method with process times typically 30% to 50% faster than centrifugation alone.
10 - 70 ml
Option of Pressure-fugation or Gas pressure filtration in addition to centrifugation
20 - 100 ml
Option of Pressure-fugation or Gas pressure filtration in addition to centrifugation
50 - 250 ml
Easy gas pressure filtration in ready-to-use device
5 - 20 ml
Unique twin vertical membranes In a single spin, sample can be concentrated up to 400x
