Looking for a game-changer in water vapor permeability testing? Meet the Labthink C370H Water Vapor Transmission Rate Test System.


This powerhouse is built on the gravimetric method, fully compliant with ASTM E96 standards, making it perfect for the pharmaceutical, food, and new energy sectors. What makes it so special? First, its 360-degree air circulating technology ensures a perfectly stable test environment. High-precision sensors monitor temperature and humidity in real-time, while the pneumatic chamber seal protects the sensitive balance from any interference. It’s incredibly versatile, too! You can test films, containers, fabrics, and more, using either the desiccant or water method.

This system is all about efficiency and accuracy. With up to nine independent test dishes, you can run multiple tests at once. The entire process is fully automatic – just set it up and let it go. Plus, the software is a dream, offering GMP-compliant data traceability and even remote control. Upgrade your lab with the C370H for precise, reliable, and automated testing.

Labthink water vapor permeability instruments are being used in important studies to improve biodegradable packaging. (1,2,3) We can help you select or customize the proper unit for your test requirements.

Case Study: Oxygen Barrier Properties of Recycled PET Bottles

Image
Recycling plastic bottles is vital for environmental protection, but it can affect their oxygen barrier properties, making them less suitable for oxygen-sensitive products. Our case study on PET bottles with varying amounts of recycled material found that increasing the recycled content from 25% to 50% only slightly reduced their oxygen barrier. This suggests that using more recycled material does not significantly compromise the bottles' performance. The Problem The growing trend of recycling waste plastic bottles requires an understanding of how reclaimed materials affect a product's performance. For PET bottles, a crucial metric is their ability to act as an oxygen barrier. High oxygen permeability can compromise the quality of packaged goods, limiting the use of recycled materials in food and beverage containers. This study aims to quantify that effect by testing bottles with varying percentages of recycled content. The Test Two types of PET bottle samples were tested...

Comprehensive Quality Control for Stretch Wrap Film Performance

Image
Stretch wrap film has become an indispensable packaging solution globally, used to tightly secure goods for efficient transportation and reliable storage. Its versatility stems from its unique properties: lightweight yet strong, highly elastic, self-adhesive, and capable of conforming to any shape without damaging the contents. Produced through advanced cast film extrusion processes, these films boast excellent tensile performance, tear and puncture resistance, high transparency, superior self-adhesiveness, and impressive retraction rates, ensuring packages remain compact and secure. From chemical raw materials and food products to electromechanical goods and textiles, stretch wrap film provides crucial protection, with specialized types like PE (eco-friendly) and PVC (specific uses) catering to diverse needs. The Imperative of Quality Control Given its critical role in safeguarding products throughout the supply chain, the consistent quality of stretch wrap film is paramount. Manufa...

Why Water Vapor Permeability is Critical for OLED Displays and How to Measure it

Image
OLED is extremely sensitivity to water vapor, even microscopic amounts of moisture can lead to rapid degradation, causing unsightly dark spots, short circuits, and significantly shortening the display's lifespan. This is why the OLED Display Water Vapor Transmission Rate Test is so important. The impact of WVTR testing extends far beyond mere measurement; it directly influences the quality, longevity, and market viability of OLED products. Ensuring OLED Device Lifespan and Performance: OLED components are extremely vulnerable to moisture. Water vapor ingress causes metal electrodes to oxidize and organic layers to degrade, leading to critical issues like dark spots and short circuits.To achieve an OLED device lifespan of at least 10,000 hours, the industry recognizes a critical WVTR target of 1 x 10 ⁻⁶ g/(m ²· day). This tester precisely measures and verifies that encapsulation materials meet this stringent requirement. Optimizing Materials and Processes: By testing the ...
