The GBPI W416 2.0 is an advanced, high-precision water vapor transmission rate tester developed for the quantitative barrier evaluation of polymer films, laminated barrier foils, coated papers, packaging membranes, and pharmaceutical blister materials. Built in strict accordance with ASTM F1249, ISO 15106-2, ISO 21760-1, GB/T 26253, and JIS K7129-2, this state-of-the-art testing station provides laboratories with unmatched analytical sensitivity, rapid cycle times, and exceptional testing repeatability.
Water vapor transmission rate (WVTR) characterization is essential across food packaging, pharmaceutical shelf-life verification, electronics encapsulation, and solar photovoltaic backsheet manufacturing. The GBPI W416 2.0 operates on the standardized infrared photometric detection principle: a specimen separates an upper humidity chamber from a lower dry carrier gas chamber. As moisture diffuses across the specimen under controlled thermodynamic vapor pressure gradients, ultra-pure nitrogen gas sweeps the permeating water molecules into a patented infrared sensor, generating continuous electrical signals directly proportional to the moisture transmission rate.
Six Independent High-Throughput Test Chambers
Engineered for high-volume quality assurance and industrial R&D facilities, the GBPI W416 2.0 water vapor transmission rate tester incorporates six fully independent test cells within a unified compact chassis. Each chamber features individual pneumatic clamping, independent temperature sensing, and automated gas flow regulation, enabling technicians to test up to six distinct specimens simultaneously or run multiple replicates without cross-interference.
Precision Thermodynamic Environment Control
Reliable barrier permeation testing demands strict control over temperature and humidity. The W416 2.0 integrates an internal thermodynamic control loop regulating specimen chamber temperature from 15 °C to 45 °C with a precision of ±0.1 °C. Relative humidity is dynamically managed across 5% to 90% RH (±1% RH) and full saturation 100% RH using an integrated dual-gas humidification system, eliminating external water bath apparatus and minimizing operational downtime.
Equipped with specialized laboratory software running on an external PC workstation, the system displays real-time permeation curves, transmission rate gradients, and chamber equilibrium statuses, with automated report generation adhering to GMP and FDA 21 CFR Part 11 electronic record compliance guidelines.
