C403M Oxygen/Water Vapor Transmission Rate Test System

C403M Oxygen/Water Vapor Transmission Rate Test System is based on the testing principles of coulometric oxygen sensor and infrared water vapor sensor. It is designed and manufactured in accordance with standards such as ASTM D3985, ASTM F1249, and ISO 15106-2. It provides a high-precision integrated testing solution for water vapor and oxygen transmission rates of high and medium barrier materials. It is widely applicable in pharmaceuticals, food, medical devices, daily chemicals, photovoltaics, electronics and other fields, accurately detecting the oxygen and water vapor transmission performances of films, packaging, sheets, and related materials.

Product Features Note 1

Combining Tests of OTR and WVTR in One

• The instrument can switch between OTR+WVTR combo test mode, OTR test mode and WVTR test mode freely, so as to satisfy varied testing needs.
• One sample mounting can automatically start and accomplish the combo test of OTR and WVTR.
• Both OTR and WVTR performances of the same sample can be accurately evaluated, avoiding sample contamination issues caused by instrument replacement.

• Equipped with a ppb-level coulometric oxygen sensor, Labthink's latest technical achievement, which can obtain a lower test limit.
• Designed according to ASTM D3985 with absolute value test principle and no need for calibration.
• Service life is three times that of traditional coulometric oxygen sensors.
• Oxygen absorption rate is as high as 95~98% (within the range).

• Equipped with Labthink infrared water vapor sensor.
• Designed according to ASTM F1249.
• Non-consumable design ensures an ultra-long service life.
• Features over-limit alarm and automatic protection functions.

• 360° airflow circulation constant temperature technology ensures superior temperature stability.
• Automated control of carrier gas flow and temperature during testing ensures higher accuracy.
• The NIST-standard humidity generation principle is applied for constant humidity.
• Equipped with high-precision temperature and humidity sensors and control systems for real-time monitoring and recording of temperature and humidity changes.
• Equipped with Labthink's independently developed gas purification system to remove trace oxygen from nitrogen, delivering ultra-pure nitrogen (optional).
• The system can achieve higher test repeatability of 0.02 cc/(m2·day).

• Three independent sets of 50 cm2 standard area test cells allow for parallel sample tests that meet standard requirements.
• Simultaneous testing of three samples under the same conditions can be performed with independent data.
• Within one test cycle, the number of samples tested is increased from two to three.

• 10" medical-grade touchscreen paired with desktop operating system offers a simple interface and convenient operation.
• Fully automated testing requires no manual intervention; data is automatically saved.
• The system is equipped with various sensors, providing intelligent alerts and enhancing operational safety.
• The system has embedded functions such as calendar, Ulti-language switching and multi-level access control, etc.
• The system has an embedded network port for convenient external access and data transmission, enabling remote upgrades.

• Next-generation platform-based computer software enables a single computer control of one or several instrument hosts (optional).
• Centralized platform-based management of test data.
• Real-time display of transmission rate curves, transmission coefficient curves, temperature curves, and humidity curves.
• Professional test mode provides flexible and comprehensive control functions to satisfy scientific research needs.
• Complies with GMP requirements for data traceability, meeting the needs of the pharmaceutical industry(optional).
• DataShield System facilitates centralized data management and integration with information system (optional).

• Variable frequency control technology is applied to achieve low-power system operation.
• Low-energy-consumption components from world-renowned brands ensure stable and reliable performance.
• Computer is nota must; the instrument can independently complete the entire testing process.
• Without a professional constant temperature laboratory, stable test data can be obtained, reducing costs for laboratory construction and daily operation and maintenance.

Testing Principle

The pre-treated sample is clamped between the test chambers. Oxygen or nitrogen with stable relative humidity flows on one side of the film, and high-purity nitrogen flows on the other side. Oxygen or water molecules diffuse through the film into the high-purity nitrogen on the other side and are carried to the sensor by the flowing nitrogen. By analyzing the oxygen or water vapor concentration measured by the sensor, the oxygen or water vapor transmission rate and other results are calculated.
