The Tech Inc. Molecular Weight Cut Off (MWCO) Testing System is a precision membrane characterization platform engineered for membrane research, pharmaceutical, and biotechnology applications. Designed in Vaughan, Canada and manufactured in Chennai, India, this system combines precision engineering with robust construction for reliable laboratory performance. Tech Inc. is a Saudi Aramco approved vendor specializing in advanced membrane technology and water treatment equipment.

Overview

The MWCO Testing System is designed to determine the molecular weight cut-off of ultrafiltration and nanofiltration membranes — the molecular weight at which 90% of solutes are rejected by the membrane. Using standardized marker solutions of PEG (polyethylene glycol), dextran, or protein molecules of known molecular weights, the system precisely characterizes membrane selectivity and pore size distribution. Both stirred cell and crossflow operation modes are supported.
