Molecular Weight Cut Off (MWCO) is the core technical indicator to judge the screening accuracy and separation performance of ultrafiltration and microfiltration membranes. Accurate MWCO detection is essential for membrane material research, product quality inspection and industrial filtration process optimization. Traditional testing equipment suffers from low detection precision, unstable pressure control and cumbersome operation, leading to inaccurate molecular weight grading data and restricting the iterative upgrading of functional membrane products. To solve industry testing pain points, GaoQ Functional Materials Co., Ltd has independently developed a high-precision molecular weight cut off tester, providing standardized and reliable detection solutions for global membrane manufacturers and scientific research institutions.

Different from conventional testing devices, GaoQ’s molecular weight cut off tester adopts a fully optimized integrated testing structure, integrating precision pressure regulation, constant temperature circulation, automatic liquid feeding and high-sensitivity sampling detection modules. The equipment supports standard dextran and PEG molecular marker testing methods, strictly complying with international industry detection standards. It can accurately test membrane MWCO values ranging from 1 kDa to 1000 kDa, covering all common specifications of commercial ultrafiltration membranes. The built-in intelligent pressure stabilization system effectively avoids flux fluctuation caused by pressure deviation, ensuring the 90% molecular retention rate test data is real and repeatable.

This tester boasts outstanding advantages in testing efficiency and operational convenience. It supports both dead-end and cross-flow testing modes, adapting to flat sheet, tubular and hollow fiber membrane samples of different structures. The automatic constant-temperature control system maintains a stable testing environment, eliminating data errors caused by temperature changes. Equipped with an intelligent data analysis system, it can automatically calculate membrane rejection rate, permeability and accurate MWCO values, and generate standardized test reports, greatly reducing manual operation errors and improving testing efficiency by more than 50% compared with traditional equipment.

Widely applicable in biomedicine, water treatment, food processing and new material research fields, GaoQ’s molecular weight cut off tester is suitable for factory batch inspection, laboratory research and third-party quality testing. All equipment undergoes strict factory calibration and stability testing, with excellent durability and low maintenance cost. Committed to functional material testing and innovation, GaoQ Functional Materials Co., Ltd continues to optimize testing equipment performance, providing precise and professional detection support for the high-quality development of the global membrane separation industry.
