CentrivaLab logo CentrivaLab™
Pump-free membrane screening

Screen multiple NF, RO and OSN membranes in a single centrifuge run.

CentrivaLab™ replaces the pressurised dead-end cell with a compact cartridge that generates 10–60 bar from centrifugal acceleration alone. Up to 8 membranes per run, with 13–22 mL of feed each, in a benchtop or floor centrifuge you may already own.

Built on the Orthogonal Centrifugal Membrane Filter (O-CMF) principle — peer-reviewed in Journal of Membrane Science (2024) and Separation and Purification Technology (2025). Suitable for aqueous NF/RO and organic solvent nanofiltration (OSN).

How CentrivaLab works

O-CMF uses centrifugal acceleration to create the hydrostatic pressure required to drive liquid through a membrane. This allows membrane screening experiments to be performed with compact sample volumes and without a full pump-driven filtration rig.

1

Load the cartridge

Feed solution and a flat membrane coupon are assembled in a compact cartridge prepared for screening.

2

Spin in a centrifuge

Centrifugal acceleration generates the pressure needed for permeation through the membrane.

3

Measure membrane performance

Flux, permeate volume and rejection can be compared across membranes, solvents and operating conditions.
