Forward Osmosis Equipment and Systems by Tech Inc.: A Complete Product Overview

Why Precision Equipment Matters in Forward Osmosis Research

Forward osmosis (FO) research is only as reliable as the equipment used to conduct it. Whether you are characterizing a novel thin-film composite membrane, evaluating draw solution performance, or optimizing operating parameters for a specific industrial application, the accuracy and reproducibility of your results depend directly on the quality, precision, and design of your laboratory testing systems.

Tech Inc. — a membrane research equipment manufacturer with roots in a 30-year-old manufacturing group specializing in filtration and separation technology — designs and develops precision-engineered FO equipment for universities, government research laboratories, and industrial R&D facilities worldwide. With leadership from Stanford University and University of Cincinnati graduates and decades of professional experience spanning Europe, the USA, and Asia, Tech Inc. brings global engineering expertise to every system it manufactures.

FO Membranes: The Foundation of Every Experiment

The FO Membrane from Tech Inc. is a commercially available flat-sheet forward osmosis membrane designed for laboratory and bench-scale testing. These membranes are engineered for high water permeability combined with excellent salt rejection, and are designed to minimize internal concentration polarization (ICP). They are suitable for draw solution screening, flux characterization studies, fouling investigations, and membrane modification research.

FO Membrane Test Cells: Precision-Engineered for Accurate Results

The Flat Sheet Rectangular SS 316 RO + FO Test Cell is a versatile, high-pressure membrane test cell manufactured from marine-grade stainless steel 316L. With a pressure rating of up to 69 bar and a 3 cm × 7 cm active membrane area, this cell is designed for both atmospheric-pressure FO experiments and high-pressure RO, nanofiltration, and pressure-assisted osmosis (PAO) studies.

The SS316L construction ensures exceptional corrosion resistance across a wide range of feed and draw solution chemistries. The rectangular channel geometry provides well-defined, uniform cross-flow conditions essential for accurate flux measurements. The dual-purpose design — supporting both FO and RO experiments in a single cell — makes this an exceptionally cost-effective investment for laboratories conducting research across multiple membrane processes.

FO Test Skids: Complete Bench-Top Testing Platforms

The Lab Test Skid for FO Membrane is Tech Inc.'s flagship forward osmosis testing platform. This fully integrated bench-top system combines the membrane test cell, pumping system, instrumentation, and plumbing into a compact, self-contained unit ready for FO research.

The system features a precision stainless steel rectangular test cell with generous active membrane area, variable-speed peristaltic pumps for independent feed and draw circuit control, and integrated instrumentation including pressure gauges, temperature sensors, conductivity meters, and flow meters. Every component has been selected and configured specifically for the unique requirements of forward osmosis testing — optimized for low-pressure, dual-circuit operation with appropriately sized pumps and instrumentation.
