As a leading provider of flexible packaging testing solutions, ShouNuo Instrument proudly launches its self‑developed product – the Oxygen Transmission Rate Tester SN‑Y103. Featuring a three‑chamber design, it brings not only efficiency improvement over traditional instruments, but also a comprehensive upgrade in test data reliability and workflow. It effectively solves the two core challenges faced by enterprises when testing multiple batches and large volumes of samples: efficiency and compliance.

【Ultra‑High Efficiency Testing – One Test, Three Results】

For quality control or R&D departments, time is the most valuable asset. Traditional single‑chamber instruments test only one sample at a time, creating a significant efficiency bottleneck. The core value of the three‑chamber design lies in parallel testing.

Parallel testing, ultra‑high efficiency – The three test chambers work independently and simultaneously, effectively tripling the throughput of a single instrument. In the same amount of time, what used to test one sample now completes three, dramatically shortening the testing cycle.

High flexibility for multiple scenarios – The three chambers can test three identical samples or three different samples under the same conditions. When comparing different material batches or evaluating multiple new materials, results are obtained in one run, avoiding repeated testing.

Excellent data consistency – The integrated three‑chamber manifold design minimizes differences in temperature, humidity, and flow rate among the three chambers, fundamentally ensuring high consistency and repeatability of parallel sample data, thereby enhancing data credibility.

Data traceability and audit – Self‑developed intelligent operating system with modular graphics, flexible test setup, and intuitive operation. Strictly designed in accordance with GMP Appendix “Computerised Systems”, featuring audit trail functionality and multi‑level user permission management, meeting the stringent requirements of the pharmaceutical industry for data traceability and compliance. Customizable reports can be generated online, reviewed, and submitted, supporting multiple data output formats for seamless integration with enterprise quality management systems.

【Application Scenarios】

The Oxygen Transmission Rate Tester SN‑Y103 is closely aligned with the testing needs of packaging, food, pharmaceuticals, new materials, chemicals, printing, and other industries. It is especially suitable for the following key scenarios:

Food packaging – Evaluate oxygen barrier performance of flexible packaging, laminated films, and containers to extend shelf life.

Pharmaceuticals & medical devices – Test high barrier properties of blister packaging, aluminum‑plastic composite films, infusion bags, etc., ensuring drug efficacy and safety.

Photovoltaic & electronic materials – Measure oxygen transmission rate of PV backsheets, encapsulation films, and electronic protective films to ensure long‑term device stability.

Daily chemicals – Analyze oxygen barrier capability of cosmetic tubes, detergent packaging, etc., to prevent oxidative degradation.

Research & quality inspection institutions – Provide accurate, traceable testing data for new material development, process improvement, and quality arbitration.

【Core Functions】

Film/sheet testing – Standard configuration, suitable for various flat barrier materials.

Package testing (optional) – OTR measurement for irregular containers such as bottles, bags, bowls, and cups.

Wide temperature range – Freely set from 5℃ to 55℃, simulating different storage and transport environments.

Real‑time monitoring & curve output – Full test visualization with automatic data curve generation.

Audit trail & permission management – Compliant with FDA 21 CFR Part 11 and GMP requirements, meeting pharmaceutical compliance needs.

Multi‑format report output – Supports PDF, Excel, etc., with online report submission and review.
