Overview

C370H Water Vapor Transmission Rate Test System is designed and manufactured based on the gravimetric method and in accordance with ASTM E96 and GB 1037. The test system provides wide-range and high-efficiency water vapor transmission rate tests for films and containers used in pharmaceutical packaging. It is also suitable for testing the water vapor permeability properties of films, containers, sheet materials, paper, fabrics, non-wovens, and related materials in food, medical device, daily chemical, and new energy sectors, etc.

Product Features^{Note 1}

Accurate Data

360° air circulating constant temperature technology ensures a stable testing environment.

Imported high-precision temperature and humidity sensors and control system monitor real-time temperature and humidity changes.

Pneumatic chamber-sealing design automatically isolates the test chamber from the weighing chamber, preventing the effects of high temperature and humidity on the balance.

Centered three-dimensional purge design ensures consistent air flow distribution over the test dishes, eliminating local deviations.

Standard air flow rate maintains a constant humidity difference between the inside and outside of the test dishes;selectable air flow rates are available.

Chamber-type fog-free humidification system eliminates the need for an internal humidifier.

German touchscreen electronic balance reaches a repeatability up to 0.3mg.

External weight calibration is available for convenient measurement.

Professional & Efficient

Tests of desiccant method and water method can be performed.

Tests of films and containers can be performed.

Screw-off test dishes, if the optional B2260 is installed, can realize automatic quantitative liquid addition and tightening.

Automatic zero reset before weighing ensures accurate measurements every time.

Cylinder lift and rotation mechanism and intermittent weighing effectively reduce system errors.

The 45L test chamber volume accommodates testing of containers of varying heights.

Independent testing of 6 or 9 test dishes with respective display of results.

Intelligent Control

10.6" medical-grade touchscreen,allowing the host to operate independently.

Fully automatic testing requires no manual intervention, and the data are stored automatically.

Wide-range, high-precision and automatic temperature and humidity control allows for easy implementation of non-standard tests.

Platform-based software allows synchronous control of multiple hosts with centralized data management.

Multiple sensors provide intelligent alerts for safer operation.

Built-in Ethernet port for direct Internet connection realizes remote control and system upgrading.

Professional computer software meets GMP data traceability requirements and pharmaceutical industry compliance needs.

Multi-level operation permission management, configurable on demand.

Electronic signature is designed in accordance with 21 CFR Part 11.

Test Principle

A pre-treated specimen is sealed in a test dish containing water or desiccant and placed in a test chamber. The test chamber automatically generates and maintains a stable temperature, humidity, and airflow environment based on specified test conditions. Water vapor diffuses through the specimen to the dry side. A high-precision balance measures the changes in the test dish's weight over time, and calculates the specimen's water vapor permeance value and other results.
