水蒸气渗透性测试仪 C370H

传输率用于水蒸气传输率温度

The C370H Pharmaceutical Packaging Water Vapor Transmission Rate Test System is based on the gravimetric testing principle and designed according to ASTM E96 and GB 1037 standards. It is specifically developed for a wide range and high-efficiency water vapor transmission rate testing of film materials and containers in the pharmaceutical packaging field. It is also suitable for testing the water vapor transmission performance of films, containers, sheets, paper, fabrics, non-woven fabrics, and related materials in food, medical devices, daily chemicals, new energy, and other industries.Accurate Data360° airflow circulation and constant temperature technology ensure a stable testing environment. Imported high-precision temperature and humidity sensors and control system monitor changes in real time.Pneumatic chamber sealing design automatically isolates the test chamber from the weighing chamber, avoiding the influence of high temperature and humidity on the balance.Central three-dimensional purge design ensures uniform wind speed distribution above the permeation cup, eliminating local deviations.Standard wind speed maintains a constant humidity difference inside and outside the permeation cup; wind speed is selectable.Chamber-type fog-free humidification system, no built-in humidifier required.German touch electronic balance, repeatability up to 0.3mg.Supports external weight calibration for convenient metrology.Professional and EfficientSupports both weight gain and weight loss methods.Supports testing of films and containers.Screw-cap permeation cup, optional B2260 for automatic quantitative liquid addition and automatic tightening.Automatic zeroing before weighing ensures accuracy for each measurement.Cylinder lifting and rotating structure with intermittent weighing measurement effectively reduces system errors.Test chamber volume: 45L, suitable for containers of different heights.6/9 permeation cups can be tested independently, with results displayed separately.Intelligent Control10.6" medical-grade touch screen, main unit can operate independently.Fully automatic testing, no manual intervention required, data is automatically stored.Wide range, high precision, automated temperature and humidity control, easy to achieve non-standard testing.Platform software can control multiple main units simultaneously, with centralized data management.Multiple sensor intelligent reminders for safer operation.Built-in network port for direct network connection, supports remote control and system upgrades.Professional computer software meets GMP data traceability requirements and pharmaceutical industry compliance.Multi-level operation permission management, configurable as needed.Electronic signature designed according to 21 CFR Part 11 requirements.Test PrincipleThe pretreated sample is sealed in a permeation cup containing water or desiccant and placed in the test chamber. The test chamber automatically generates and maintains stable temperature, humidity, and airflow according to specified test conditions. Water vapor diffuses through the sample to the dry side, and the high-precision balance measures the change in the total weight of the permeation cup over time to calculate the water vapor transmission rate of the sample.Reference StandardsASTM E96, GB/T 1037, GB/T 16928, ASTM D1653, ISO 2528, TAPPI T464, DIN 53122-1, YBB00092003Test ApplicationsBasic ApplicationsFilmsWater vapor transmission rate testing for various plastic films, composite films, paper-plastic composite films, co-extruded films, metallized films, aluminum foil composite films, glass fiber aluminum foil paper composite films, etc.ContainersWater vapor transmission rate testing for various pharmaceutical packaging bottles, bags, Tetra Pak packaging, three-piece cans, cosmetic packaging, toothpaste tubes, jelly cups, yogurt cups, and bottles, bags, cans, boxes, barrels made of plastic, rubber, paper, paper-plastic composite, glass, metal, etc.SheetsWater vapor transmission rate testing for PP sheets, PVC sheets, PVDC sheets, metal foil sheets, rubber sheets, etc.Paper, Paperboard & CompositesWater vapor transmission rate testing for cigarette pack metallized paper, paper-aluminum-plastic composite sheets, etc.Textiles, Non-woven FabricsWater vapor transmission rate testing for geotextiles, felts, insulation felts, thick sheet waterproof insulation building materials, etc.Extended ApplicationsBuilding MaterialsWater vapor transmission rate testing for geotextiles, felts, insulation felts, thick sheet waterproof insulation building materials, etc.Sterile Wound Dressings, Medical PlastersWater vapor transmission performance testing for sterile wound dressings, medical plasters, etc.Technical ParametersParameter/ModelC370HTest Rangeg/(m²·day)0.1–10000 (weight loss method)0.1–2500 (weight gain method)Balance Capacityg220Balance Resolutionmg0.1Balance Repeatabilitymg0.3Temperature Range℃15–50Temperature Fluctuation℃±0.2Humidity Range%RH10–90% ±2%Extended Functions21 CFR Part 11OptionalGMP Computer System RequirementsOptionalTechnical SpecificationsTest Stations6; 9 (customizable)Test MethodsWeight gain method, weight loss methodSample TypesFilms, containersWind Speed0.02~0.3m/s, 0.5~2.5m/sSample SizeΦ 4.2” (74mm)Sample Thickness≤120 Mil (3mm)Test Area33cm²; 50cm² (optional)Container Size≤Φ70 mm×180mm (customizable)Gas SpecificationCompressed air (user supplied)Gas Pressure72.5 PSI / 500 kPaInterface SizeΦ8 mm polyurethane tubeMain Unit Dimensions29” H x 23” W x 30” D (73cm× 57cm× 76cm)Power Supply120VAC±10% 60Hz / 220VAC±10% 50Hz (selectable)Net Weight187Lbs (85kg)Product ConfigurationStandard ConfigurationMain unit, electronic balance, air dryer (maintenance-free), filter pressure reducing valve, precision permeation cups (6), permeation cup disassembly tool, power cord, Φ8 mm polyurethane tubeOptional AccessoriesSoftware, GMP computer system requirements, 21 CFR Part 11, air compressor (exhaust ≥200L/min), precision permeation cup, B2260 permeation cup tightening deviceNote: For users with special requirements, our company can provide customized production within our capabilities to meet user needs.Labthink is committed to continuous innovation and improvement of product performance and functions.
