The GBPI Y110L is an advanced, compact oxygen transmission rate tester engineered for the quantitative barrier characterization of polymer films, plastic sheets, multi-layer barrier laminates, and packaging foils. Built in full compliance with standardized equal-pressure coulometric testing protocols including ASTM D3985, ISO 15105-2, ASTM F1927, DIN 53380-3, and JIS K7126-2, this space-efficient benchtop instrument provides quality assurance laboratories and R&D departments with high-precision analytical capability.
Oxygen ingress is one of the primary drivers of quality degradation in food, beverage, medical packaging, and electronic components. The GBPI Y110L oxygen transmission rate tester operates on the standardized coulometric sensor detection principle: a circular test specimen is hermetically clamped inside the test cell, dividing it into an upper oxygen gas chamber and a lower carrier gas chamber. High-purity dry nitrogen sweeps both chambers during pre-test degassing to purge ambient gases and stabilize the sensor baseline. Once stable, high-purity oxygen flows through the upper chamber, establishing a constant partial pressure difference. Oxygen molecules diffusing through the barrier membrane are carried by the flowing nitrogen stream to an electrochemical coulometric sensor, where oxygen is reduced to generate an electrical current that directly correlates with the sample's oxygen transmission rate (OTR).
Compact Benchtop Design with High Sensitivity
Developed specifically for facilities with limited bench space, the GBPI Y110L integrates thermal management, precision gas routing manifolds, and sensor electronics into a streamlined chassis measuring just 440 × 680 × 380 mm. With an ultra-low measurement resolution of 0.0001 cm³/(m²·24h·0.1MPa), the instrument reliably characterizes high-barrier metallized films as well as medium-barrier packaging polyolefins.
Automated Thermodynamic Environment Control
The instrument incorporates an internal constant-temperature circulation block regulating cell temperature between 15 °C and 45 °C with ±0.2 °C precision. A built-in dual gas humidification circuit allows tests to be conducted across dry conditions (0% RH) up to saturated humidity (100% RH), reflecting real-world shelf storage environments.
The accompanying PC software interface delivers automated baseline zeroing, real-time curve plotting, certified reference film calibration protocols, and multi-tier user password security conforming to modern laboratory data integrity guidelines.
