水蒸気通気性試験機 C370H

透過率水蒸気透過率温度

C370H Water Vapor Transmission Rate Test System is designed and manufactured based on the gravimetric method (cup method), in compliance with ASTM E96 and GB 1037. This test system provides a wide range and high-efficiency water vapor transmission rate testing for pharmaceutical packaging films and containers. It is also suitable for water vapor permeability testing of films, containers, sheet materials, paper, textiles, nonwovens, and related materials in the fields of food, medical devices, daily chemicals, and new energy.Product Features360° air circulation constant temperature technology ensures a stable test environment.Imported high-precision temperature and humidity sensors and control system monitor real-time changes.Pneumatic chamber seal design automatically separates the test chamber and weighing chamber, preventing the influence of high temperature and humidity on the balance.Centralized three-dimensional purge design ensures uniform airflow distribution across the test dish, eliminating local deviations.Standard airflow speed maintains a constant humidity difference inside and outside the test dish. Airflow speed is selectable.Chamber-type anti-fog humidification system eliminates the need for an internal humidifier.German-made touchscreen electronic balance achieves reproducibility up to 0.3 mg.External weight calibration is possible for easy measurement.Professional and EfficientSupports both desiccant and water methods.Capable of testing both films and containers.With optional B2260, automatic quantitative liquid addition and tightening are possible with screw-off test dishes.Automatic zero reset before weighing ensures accurate measurement every time.Cylinder lift and rotation mechanism with intermittent weighing effectively reduce system errors.45L test chamber capacity accommodates containers of various heights.6 or 9 test dishes can be tested individually, with results displayed separately.Intelligent Control10.6-inch medical-grade touchscreen allows independent host operation.Fully automatic testing eliminates manual operation; data is saved automatically.Wide-range, high-precision, automatic temperature and humidity control enables easy non-standard testing.Platform-based software enables synchronized control of multiple hosts and centralized data management.Multiple sensors provide intelligent alarms for safer operation.Built-in Ethernet port for direct internet connection, remote operation, and system upgrades.Professional computer software meets GMP data traceability and pharmaceutical industry compliance needs.Multi-level operation authority management can be set as needed.Electronic signatures are designed in compliance with 21 CFR Part 11.Test PrinciplePre-treated test specimens are sealed in test dishes containing water or desiccant and placed in the test chamber. The chamber automatically generates and maintains a stable temperature, humidity, and airflow environment according to specified test conditions. Water vapor permeates the specimen and diffuses to the dry side. A high-precision balance measures the weight change of the test dish over time, calculating the water vapor transmission rate and other results.Reference StandardsASTM E96, GB/T 1037, GB/T 16928, ASTM D1653, ISO 2528, TAPPIT464, DIN 53122-1, YBB00092003Test ApplicationsBasic ApplicationsFilmsWater vapor transmission rate testing for various plastic films, plastic composite films, paper-plastic composite films, co-extruded films, metallized films, aluminum foil composite films, glass fiber aluminum foil paper composite films, and other film materials.ContainersWater vapor transmission rate testing for various pharmaceutical packaging bottles, pouches, Tetra Pak packaging, three-piece cans, cosmetic packaging, toothpaste tubes, jelly cups, yogurt cups, and other bottles, pouches, cans, boxes, barrels made of plastic, rubber, paper, paper-plastic composites, glass, and metal.Sheet MaterialsWater vapor transmission rate testing for PP sheets, PVC sheets, PVDC sheets, metal foils, rubber sheets, and other sheet materials.Papers, Paperboards, and Related CompositesWater vapor transmission rate testing for paper and paperboard (e.g., aluminum vapor-deposited paper for tobacco packaging, paper-aluminum-plastic composite sheets, etc.).Textiles & NonwovensWater vapor transmission rate testing for textiles, nonwovens, and other materials.Building MaterialsBuilding MaterialsWater vapor transmission rate testing for geotextiles, felts, insulation felts, thick waterproof and insulation building materials, etc.Sterile Wound Dressings, Medical PlastersWater vapor transmission rate testing for sterile wound dressings, medical plasters, etc.Technical ParametersParameter ModelC370HTest Rangeg/(m²·day)0.1–10,000 (Water Method)Note 30.1–2500 (Desiccant Method)Note 3Weighing Rangeg220Balance Resolutionmg0.1Balance Reproducibilitymg0.3Temperature Range°C15–50Temperature Fluctuation°C±0.2Humidity Range%RH10–90% ±2%Extended Functions21 CFR Part 11OptionalGMP Computer System RequirementsOptionalTechnical SpecificationsNumber of Test Samples69 (customizable)Test MethodsDesiccant and Water MethodsTest MethodsFilm, ContainerNote 4Air Flow Rate0.02–0.3 m/s, 0.5–2.5 m/sSample SizeΦ4.2 inches (74 mm)Sample Thickness≤120 mil (3 mm)Test Area33 cm²50 cm² (optional)Container Size≤Φ70 mm × 180 mm (customizable)Gas SpecificationCompressed air (user-supplied)Gas Source Pressure72.5 PSI / 500 kPaPort SizeΦ8 mm polyurethane tubeMain Unit DimensionsHeight 29 in × Width 23 in × Depth 30 in (73 cm × 57 cm × 76 cm)Power Supply120VAC ±10% 60Hz / 220VAC ±10% 50Hz (selectable)Net Weight187 lbs (85 kg)Product ConfigurationStandard ConfigurationMain unit, electronic balance, air dryer (maintenance-free), pressure reducing filter valve, precision water vapor test dishes (6 pcs), disassembly tool for water vapor test dishes, power cord, Φ8 mm polyurethane tubeOptional AccessoriesSoftware, GMP computer system requirements, 21 CFR Part 11, air compressor (flow ≥200L/min), precision water vapor test dishes, B2260 tightening device for water vapor test dishesNotes:Product specifications are based on the specific specifications in the "Technical Specifications" table.All parameters in the table were measured by professional operators in the Labthink laboratory according to relevant laboratory environmental standards and conditions.Maximum range = maximum range / n (n is 1–6).Test accessories for container specimens need to be customized according to the specimen size.Labthink is committed to innovation and improvement of product performance and functionality.
