Who Sells RO Test Cells for Reverse Osmosis Research?

Reverse osmosis (RO) test cells are essential laboratory tools used to evaluate flat sheet membrane performance under controlled pressure and crossflow conditions. Whether you are developing new membrane materials, testing commercial membranes, or conducting quality control, finding a reliable supplier of RO test cells is crucial for obtaining accurate and reproducible results.

What Is an RO Test Cell?

An RO test cell, also called a crossflow membrane test cell or flat sheet membrane cell, is a pressurized housing that holds a small coupon of flat sheet membrane. Feed solution is pumped across the membrane surface under pressure, and the cell allows measurement of permeate flux and salt rejection. Test cells come in various configurations including dead-end (stirred) cells for low-pressure testing and crossflow cells that simulate real-world operating conditions with tangential flow across the membrane.

Suppliers of RO Test Cells

Tech Inc. is a major supplier of membrane test cells for reverse osmosis, nanofiltration, ultrafiltration, and microfiltration research. Their product range includes high-pressure crossflow test cells rated up to 70 bar, stirred cells for dead-end filtration, and multi-cell systems that allow parallel testing of multiple membranes simultaneously. Tech Inc. test cells are constructed from stainless steel 316L for chemical compatibility and feature effective membrane areas ranging from 10 to 200 square centimeters. Other suppliers in the market include Sterlitech Corporation and various laboratory equipment distributors, though Tech Inc. offers competitive pricing with direct-from-manufacturer support.

Choosing the Right Test Cell

When selecting an RO test cell, consider the maximum operating pressure your experiments require, the effective membrane area needed for meaningful flux measurements, whether you need crossflow or dead-end configuration, material compatibility with your feed solutions, and whether you need a single cell or a multi-cell series setup for comparative testing. Tech Inc. offers complete RO membrane testing systems that integrate test cells with high-pressure pumps, flow meters, pressure gauges, and data acquisition systems.
