Labthink has launched a new C370H pharmaceutical packaging water vapor transmission rate testing system, which is designed to provide a wide range and high efficiency water vapor transmission rate detection for products such as films, containers, paper, fabrics, non-woven fabrics, etc. This device is based on the principle of weight method testing and adopts an integrated design of increasing and decreasing weight. It is compatible with film and container testing and fully meets the requirements of mainstream standards such as ASTM E96, GB/T 1037, Chinese Pharmacopoeia, ISO 2528, TAPPI T464, DIN 53122-1, etc. It provides accurate and reliable quality control solutions for related industries such as medicine, healthcare, food, daily chemical, and new energy.

Add/Remove Weight Integration · Expand Container Testing

The C370H water vapor permeability testing system adopts a dual testing mode of weight method - weight gain method and weight loss method. Users can flexibly choose the appropriate method according to material characteristics and testing range requirements. This device not only supports conventional sample testing such as films and sheets, but also expands its application scope through customized accessories, achieving precise detection of drug containers such as oral liquid bottles, external preparation containers, infusion containers, and other forms of containers.

The container testing process strictly follows the requirements of the "weight reduction method" in General Rule 4010 "Determination of Water Vapor Transmittance" of the 2025 edition of the Chinese Pharmacopoeia, ensuring the standardization and authority (separation) of the test results. The 45L large capacity test chamber design can fully accommodate packaging containers of different heights, effectively meeting the testing needs of industries such as pharmaceuticals and food for actual packaging forms.

As the core of the weight based water vapor transmission rate test, the weighing system of the C370H water vapor transmission rate test system uses a high-precision balance imported from Germany with a resolution of 0.1mg, which can capture extremely weak weight changes. On this basis, Labthink adopts innovative isolation technology - pneumatic sealing chamber, which achieves complete (separation) isolation between the test chamber and the weighing chamber in non weighing state, fundamentally preventing interference from high temperature and high humidity environment on the precision balance. This technology not only meets the requirements of extreme (separated) end environment testing, but also maintains the accuracy stability of the weighing system for a long time.

In addition, the system adopts 360 ° airflow circulation constant temperature technology, combined with a central three-dimensional blowing design, effectively eliminating local temperature and airflow unevenness, and avoiding data deviation caused by temperature and humidity fluctuations inside and outside the moisture permeable cup. Wide range temperature control of 15-50 ℃ and precise humidity control of 10-90% ± 2% RH help users simulate various environments from conventional storage to extreme conditions, providing comprehensive data references for material performance verification and research.

In terms of testing efficiency, the C370H water vapor permeability testing system adopts a standard configuration of 6 stations (expandable to 9 stations), supporting synchronous testing of different samples and improving parallel testing efficiency. By selecting the B2260 automation module, it is easy to achieve standardized operations for quantitative liquid addition and tightening, completely eliminating the risk of errors caused by manual sealing differences and ensuring data repeatability. The entire testing process does not require manual intervention and supports 24-hour continuous automatic testing and data storage.

In response to the strict compliance requirements of the pharmaceutical industry, the system can be configured with professional customized software that meets GMP data traceability requirements, with optional 21 CFR Part 11 functions, built-in audit tracking and electronic signatures, providing complete audit support for pharmaceutical companies.

As another innovative achievement of Labthink in the field of weighing and moisture permeability testing, the C370H pharmaceutical packaging water vapor permeability testing system significantly enhances users' testing experience through comprehensive coverage of testing methods, diversified sample adaptation, innovative precision weighing structures, and efficient and compliant testing processes. It provides customers in industries such as medicine, healthcare, and packaging with a complete solution from material research and development to quality control.
