The C370H Water Vapor Transmission Rate Test System is based on the gravimetric method and complies with ASTM E96 and GB 1037 standards. It enables comprehensive and highly efficient testing of the water vapor permeability of films and containers for pharmaceutical packaging. Additionally, it is suitable for testing the water vapor permeability of films, containers, sheet materials, paper, textiles, nonwovens, and related materials in the food, medical device, cosmetics, and energy industries.Accurate Data360° air circulation technology with constant temperature ensures a stable test environment.World-renowned, high-precision temperature and humidity sensors and a control system monitor temperature and humidity changes in real time.Pneumatic chamber sealing automatically separates the test chamber from the weighing chamber, preventing the effects of high temperature and humidity on the balance.The centered, three-dimensional flushing design ensures uniform airflow distribution over the test area and eliminates local deviations.The standard airflow rate maintains a constant humidity difference between the inside and outside of the test cups; selectable airflow rates are available.The chamber-like, fog-free humidification system eliminates the need for an internal humidifier.The German electronic touchscreen balance achieves repeatability up to 0.3 mg.External weight calibration enables convenient measurement.Professional & EfficientTesting with desiccant and water methods possible.Testing of films and containers possible.With the optional B2260, screwable test cups can be automatically filled with liquid and screwed shut.Automatic zero adjustment before weighing ensures precise measurements at all times.Cylinder lifting and rotating mechanism as well as intermittent weighing effectively reduce system errors.The 45-liter test chamber volume enables testing of containers of different heights.Independent testing of 6 or 9 test cups with individual result display.Intelligent Control10.6-inch medical-grade touchscreen for autonomous operation.Fully automatic tests without manual intervention; data is automatically saved.Broadband, high-precision, and automatic temperature and humidity control enables easy execution of non-standardized tests.Platform-based software enables synchronous control of multiple hosts with centralized data management.Multiple sensors provide intelligent warnings for safer operation.The integrated Ethernet port for direct Internet connection enables remote control and system updates.Professional computer software meets GMP data traceability and compliance requirements of the pharmaceutical industry.Multi-level authorization management, configurable as needed.The electronic signature is designed according to 21 CFR Part 11.Test PrincipleA pretreated sample is sealed in a test dish filled with water or desiccant and placed in a test chamber. The test chamber automatically generates and maintains a stable temperature, humidity, and airflow according to the specified test conditions. Water vapor diffuses through the sample to the dry side. A high-precision balance measures the weight change of the test dish over time and calculates the water vapor permeability of the sample and other results.Reference StandardsASTM E96, GB/T 1037, GB/T 16928, ASTM D1653, ISO2528, TAPPI T464, DIN 53122-1, YBB00092003Test ApplicationsBasic ApplicationsFilmsWater vapor permeability testing of various plastic films, plastic composite films, paper-plastic composite films, coextruded films, metallized films, aluminum foil composite films, glass fiber-aluminum foil-paper composite films, and other film materials.PackagingWater vapor permeability testing for various pharmaceutical packaging bottles, bags, Tetra Pak packaging, three-piece cans, cosmetic packaging, toothpaste tubes, jelly cups, yogurt cups, and other bottles, bags, cans, boxes, and barrels made of plastic, rubber, paper, paper-plastic composite, glass, and metal.Sheet MaterialsWater vapor permeability testing of sheet materials such as PP sheets, PVC sheets, PVDC sheets, metal foils, rubber sheets, etc.Papers, Cardboards, and Related CompositesWater vapor permeability testing of paper and cardboard, such as aluminized paper for cigarette packaging and paper-aluminum-plastic composite boards.Textiles and NonwovensWater vapor permeability testing of textiles, nonwovens, and other materials.Advanced ApplicationsBuilding MaterialsWater vapor permeability testing of geotextiles, felts, thermal insulation felts, thick boards made of waterproof and thermal insulation building materials, etc.Sterile Wound Dressings, Medical PlastersWater vapor permeability testing of sterile wound dressings, medical plasters, etc.Technical DataTable 1: Test ParametersParameter ModelC370HTest Rangesg/(m²·day)0.1 ～ 10,000 (Water) Note 30.1 to 2500 (Desiccant) Note 3Balanceg220Resolutionmg0.1Repeatabilitymg0.3Temperature Range℃15–50Temperature Fluctuation℃±0.2Humidity Range%RH10～90%±2%Advanced Functions21 CFR Part 11OptionalGMP Computer System RequirementsOptionalTable 2: Technical SpecificationsTest Stations69 (on customer request)Test MethodDesiccant and WaterSample TypesFilms, Packaging Note 4Airflow0.02–0.3 m/s, 0.5–2.5 m/sSample SizeΦ4.2” (74 mm)Sample Thickness≤120 Mil (3 mm)Test Areas33 cm²50 cm² (optional)Container Size≤Φ70 mm×180 mm (customizable)Gas SpecificationCompressed air (gas source to be provided by user)Gas Source Pressure72.5 PSI / 500 kPaPort SizePolyurethane tube with Φ8 mm diameterHost Dimensions29 in H x 23 in W x 30 in D (73 cm × 57 cm × 76 cm)Power Supply120 V AC ± 10% 60 Hz / 220 V AC ± 10% 50 Hz (choose one)Net Weight187 lbs (85 kg)Table 3: Product ConfigurationStandard ConfigurationTest device, electronic balance, maintenance-free air dryer, pressure reducing valve, precision water vapor test cups (6 pcs), disassembly tool for water vapor test cups, power cord, polyurethane tube (Ø 8 mm)Optional ItemsSoftware, GMP computer system requirements, 21 CFR Part 11, air compressor (with a delivery rate of ≥ 200 l/min), precision water vapor test cups, B2260 closure device for water vapor test cupsTechnical Features / SpecificationsTest method: gravimetric (cup method), compliant with ASTM E96, GB 1037Test range: 0.1–10,000 g/(m²·day) (water), 0.1–2500 g/(m²·day) (desiccant)Resolution: 0.1 mg; Repeatability: 0.3 mgTemperature range: 15–50°C; Fluctuation: ±0.2°CHumidity range: 10–90%RH ±2%Test stations: 6 or 9 (optional)Sample size: Φ4.2” (74 mm); Sample thickness: ≤120 Mil (3 mm)Host dimensions: 73 cm × 57 cm × 76 cmNet weight: 85 kgPower supply: 120 V AC ± 10% 60 Hz / 220 V AC ± 10% 50 Hz
