Labthink C406H Revolutionizing Oxygen & Water Vapor Barrier Performance Combi Testing System Driving Value Across Diverse Industries

In industries where packaging integrity is paramount – such as food, pharmaceuticals, and medical devices – ensuring robust barrier performance is non-negotiable. Conventional testing frequently suffer from three key pain points: Single-function instruments need frequent sample changes, leading to significant downtime and the risk of cross-contamination; integrating multiple specialized devices for comprehensive analysis is costing and complex; reliance on manual operations introduces human error, making ensuring consistent and reliability difficult. Labthink C406H Oxygen/Water Vapor Transmission Rate Testing System emerges as a groundbreaking “one-system, dual-test” solution, meticulously engineered to overcome these pervasive challenges and redefine industry standards.

Labthink C406H directly targets these issues, providing a streamlined and reliable testing platform. It integrates Labthink’s proprietary ppb-level coulometric oxygen sensor with a patented infrared water vapor sensor. The oxygen sensor has an impressive lower detection limit of 0.02 cc/(m²·day), far more precise comparing to conventional equipment. The infrared water vapor sensor offers rapid response times, accurately capturing permeation rates as low as 0.0001 g/(m²·day). Both sensors are offering a lifespan three times that of traditional counterparts, complemented by an integrated over-limit alarm system for continuous operational stability.

Beyond its sensing capabilities, the C406H features a novel “Rainbow Bridge” test chamber design. This, combined with 360° airflow circulation and precise constant temperature technology, ensures temperature fluctuations remain within ±0.15℃. High-accuracy temperature and humidity sensors are embedded in each chamber, providing real-time environmental monitoring and data logging.

C406H’s six independent test chambers design boosted test efficiency significantly, allowing for the simultaneous analysis of six samples. This multi-sample capability is particularly beneficial for research institutions conducting comparative studies.

Operation is automated via a 12-inch Windows touchscreen tablet, powered by an embedded industrial computer. Users simply input desired temperature and humidity parameters, and the system autonomously manages gas flow, temperature, and humidity, achieving a repeatability of 0.01 cc/(m²·day). Smart features like automatic cover opening/closing with acoustic and visual alerts further enhance user experience.

Driving Value Across Diverse Industries

1. Food Industry Quality Assurance: It precisely simulates diverse environmental conditions to assess oxygen barrier properties (0.02-200 cc/(m²·day)) and water vapor transmission rates (0.005-40 g/(m²·day)). For instant, meat packaging, accurate oxygen permeation testing directly aids in controlling fat oxidation, thereby extending product shelf life.
2. Pharmaceutical Packaging Safety: For high-barrier materials such as aluminum foil composite films in drug packaging, the C406H can detect ultra-low water vapor transmission at 0.0001 g/(m²·day). This ensures the stability of humidity-sensitive drugs, reduce the risk of quality issues caused by moisture and preventing costly recalls due to packaging failure.
3. Medical Device Innovation: In medical device testing, such as wound dressings, the C406H concurrently measures both oxygen and water vapor transmission rates. This provides comprehensive dual-data support crucial for material selection and product development.
4. Regulatory Compliance & Quality Control: The system is engineered to meet international standards including ASTM D3985 and ISO 15106-2, and adheres to critical regulatory requirements like GMP and CFR21 Part11.
