High-Throughput Centrifugal Membrane Screening

CentrivaLab is a rotor-matched cartridge platform for rapid screening of nanofiltration (NF) and reverse osmosis (RO) membranes under controlled hydrodynamic conditions, based on Ortho-Centrifugal Membrane Filter (O-CMF) technology. Validated against bench-scale crossflow units, it delivers uniform pressure, minimal polarization, and scalable results.

Current Standard Configuration

CentrivaLab 50/34°
Designed for 50 mL fixed-angle rotors at 34°. Supports up to 50 bar pressure for NF/RO.

Custom versions available for other 50 mL or 96–100 mL formats.

Technology

CentrivaLab leverages the Ortho-Centrifugal Membrane Filter (O-CMF) principle, where centrifugal force drives permeation through a flat-sheet membrane positioned for uniform pressure and reproducible hydrodynamics. Introduced in seminal research and validated for scaled-down screening, O-CMF ensures minimal concentration polarization via centrifugal convection, as confirmed by CFD simulations.

Why CentrivaLab?

Validated against bench-scale crossflow units, CentrivaLab combines low sample consumption (<10 mL), rapid turnaround (~5 min assembly), near-zero permeate hold-up, and realistic (spiral-wound-like) concentration polarization for efficient membrane screening.

Scientific Validation

CentrivaLab is grounded in peer-reviewed research on O-CMF design, hydrodynamics, concentration polarization, and scaled-down membrane screening. An upcoming article co-authored with Professor Menachem Elimelech will further advance predictive modeling.
