Clinical Diagnostic Labs
Clinical labs prefer either static or centrifugal concentrators. Static concentrators such as the BJP line and the VIVAPORE offer less interaction whereas the centrifugal concentrators are much faster. Both options use the same polysulfone membrane that guarantees the highest recovery rates.

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 characterized 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
5 - 20 ml
Unique twin vertical membranes In a single spin, sample can be concentrated up to 400x
500 µl - 2.5 ml
For very viscous or particle-containing liquids (i. e. serum/blood samples)
Static Filtration
0.5 to 20 ml starting volume
This technique uses an absorbent cellulose pad mounted behind the ultrafiltration membrane to draw solvents and micro solutes through the membrane. Retained macromolecules are concentrated into the bottom of the sample container. No additional equipment is required.
0.5 - 5 ml
BJP concentrators offer fast and convenient means to concentrate multiple clinical or research samples for analysis by electrophoresis or immunofixation.
1 - 10 ml
BJP concentrators offer fast and convenient means to concentrate multiple clinical or research samples for analysis by electrophoresis or immunofixation.
2 - 20 ml
BJP concentrators offer fast and convenient means to concentrate multiple clinical or research samples for analysis by electrophoresis or immunofixation.
0.5 - 2 ml
Optimal for urine concentration - no need for additional equipment, pressure or vacuum
0.5 - 5 ml
Optimal for urine concentration - no need for additional equipment, pressure or vacuum
0.5 ml - 20 ml
Optimal for urine concentration - no need for additional equipment, pressure or vacuum
