The C370H Water Vapor Transmission Rate Test System uses the gravimetric (weight) method and is designed and manufactured in accordance with ASTM E96 and GB 1037 standards. It offers a wide range and high testing efficiency for films and containers used in pharmaceutical packaging. The instrument can also determine the water vapor permeability of not only films and containers, but also paper, textiles, nonwovens, multilayer, and other packaging materials for food, household chemicals, medical devices, new energy sources, etc.Data Accuracy360° forced air circulation maintains constant temperature and other test conditions.Imported high-precision temperature and humidity sensors and a control system monitor changes in real time.The test chamber and weighing chamber are automatically separated by air sealing to prevent high temperature and humidity from affecting the scales.Centralized volumetric purging ensures uniform airflow distribution among test cups, eliminating local deviations.Standard airflow maintains a constant humidity difference inside and outside the test cups, with selectable airflow speed.Fog-free chamber humidification system eliminates the need for an internal humidifier.German electronic scales with a touchscreen ensure repeatability up to 0.3 mg.External calibration of weights is available for convenience.Professionalism and EfficiencyTesting can be performed using both “dry” and “wet” methods.Suitable for testing both films and containers.Screw-in test cups and optional B2260 device allow automatic liquid dosing and cup tightening.Automatic zeroing before each weighing ensures measurement accuracy.Cylinder lifting and rotation mechanism and periodic weighing significantly reduce system errors.Test chamber volume of 45 L allows testing of containers of various heights.Independent testing of 6 or 9 cups with results displayed on the screen.Intelligent Control10.6-inch touchscreen for independent operation.Fully automatic testing with automatic data saving requires no operator intervention.Wide range and high-precision automatic temperature and humidity control allow for non-standard tests.Platform-based software enables synchronous control of multiple instruments and centralized data management.Multiple sensors provide intelligent alerts for safer operation.Built-in Ethernet port for internet connection supports remote management and system updates.Professional PC software complies with GMP requirements for data traceability and other pharmaceutical industry standards.Multi-level user authorization system allows customization on request.Electronic signature complies with 21 CFR Part 11.Test MethodPre-treated sample is placed in a test cup containing water (“wet” method) or desiccant (“dry” method) and installed in the test chamber, where stable temperature, humidity, and airflow are automatically maintained according to the set test conditions. Water vapor passes through the sample to the dry side. High-precision scales measure the change in mass of the test cup over time and calculate the sample’s water vapor permeability and other parameters.Compliance StandardsASTM E96, GB/T 1037, GB/T16928, ASTM D1653, ISO 2528, TAPPI T464, DIN 53122-1, YBB00092003.Application AreasMain ApplicationsFilm MaterialsVarious polymer films (including composite), paper-polymer films, co-extruded films, metallized films, composite aluminum foil, glass-reinforced and laminated aluminum foil films on paper base, etc.ContainersVarious pharmaceutical packaging (bottles, bags, Tetra Pak), metal cans, cosmetic packaging, toothpaste tubes, jelly and yogurt cups, as well as bottles, pouches, cans, boxes, and barrels made of plastic, rubber, paper, paper-laminated materials, glass, and metal.Sheet MaterialsPolypropylene, PVC, PVDC, metal foil, sheet rubber, etc.Papers, Cardboard, and Multilayer Paper-based MaterialsPapers and cardboard, aluminized paper for cigarette packs, composite materials based on paper, aluminum, or plastic.Textile and Nonwoven MaterialsTextile, nonwoven, and other materials.Additional ApplicationsBuilding MaterialsGeotextiles, felt, felt insulation, thick waterproof and thermal insulation building materials, etc.Sterile Dressings, Medical PatchesSterile dressings, medical patches, etc.Technical SpecificationsParameter / ModelC370HTest Rangeg/(m2·day)0.1–10,000 (“wet” method)0.1–2,500 (“dry” method)Weighing Rangeg220Scale Resolutionmg0.1Weighing Repeatabilitymg0.3Temperature Range°C15–50Temperature Fluctuation°C±0.2Humidity Range%10–90 ±2Additional Functions21 CFR Part 11OptionalGMP-compliant computer systemOptionalNumber of Measuring Stations69 (custom order)Test Method“dry” and “wet” methodsSample Typefilms, containersAirflow Rate0.02–0.3 m/s, 0.5–2.5 m/sSample SizeØ 74 mmSample Thickness≤ 3 mmControlled Area33 cm250 cm2 (optional)Container Size≤ Ø 70 × 180 mm (custom order)Gas Characteristicscompressed air (supplied by user)Gas Supply Pressure500 kPaConnection Sizepolyurethane tube Ø 8 mmInstrument Dimensions (H × W × D)73 × 57 × 76 cmPower Supply120 V AC ±10%, 60 Hz / 220 V AC ±10%, 50 Hz (selectable)Net Weight85 kgStandard ConfigurationInstrument, electronic scales, maintenance-free air dryer, filter pressure reducing valve, precision test cups (6 pcs), tools for dismantling test cups, power cord, polyurethane tube Ø 8 mmOptional ComponentsSoftware compliant with GMP and 21 CFR Part 11, air compressor ≥200 L/min, precision test cups, B2260 cup tightening deviceNote 1: Product features are based on the specific specifications listed in the “Technical Specifications” table.Note 2: All values in the tables were measured by professional operators in the Labthink laboratory under the laboratory conditions specified in the standards.Note 3: Maximum range = Maximum measurement range / n, where n is from 1 to 6.Note 4: Accessories for container testing should be optimized according to sample sizes.Labthink is committed to innovation and continuous improvement of its products; therefore, technical specifications may change without prior notice.
