C230M Oxygen Transmission Rate Test System is designed and manufactured based on coulometric sensor method (aka. equal pressure method) and conforms to the requirements of ISO 15105-2/ASTM D3985. This instrument can be used to measure the oxygen transmission rate of barrier materials with high, medium and lower barrier properties with a wide testing range and high testing efficiency. The instrument is featured with patented design of integrated block consisting of 3 test cells. Equipped with high precision sensors and professional computer-controlled system, the instrument can regulate and control the temperature, humidity and flow rate properly, which guarantee the testing sensitivity and repeatability of test results. C230 is applicable to determination of oxygen permeability of plastic films, sheeting, paper, packages and other relative packaging materials in food, pharmaceutical, medical apparatus, daily chemical, photovoltaic and electronic industries, etc.
The instrument uses Labthink’s new generation gas analytical sensor, which is developed by Labthink Global Research & Development Center, collecting top class scientific and technical achievements in Chinese and American sensor technology fields. With core sensor technology, the precision and stability reach world advanced level.
With 30 years’ experience, Labthink has most mature and reliable manufacturing technology of gas permeability testing instruments. Labthink provides customers with high-end barrier property testing instruments with best design, best material, best performance and best sensor by continuously adjusting the details, completing the designs and improving the performance.
By studying various test methods of gas transmission rate, Labthink manufactures many gas permeability testing instruments based on ISO 15105-2/ASTM D3985 (equal pressure method) and ISO 2556/ISO 15105-1/ASTM D1434 (differential pressure method). Labthink has the most complete product line of gas permeability testing instruments in packaging industry worldwide.
Labthink is dedicated to providing customers with suitable products. From scientific tracing method to commercially applied method, from scientific research to quality control, you will finally find the products that are suitable for you. C230M Oxygen Transmission Rate Test System is one of those products.
The pre-conditioned specimen is mounted between the upper and lower chambers at ambient atmospheric pressure. One chamber contains oxygen or air and the other chamber is slowly purged by a stream of nitrogen. Due to the concentration difference between the two chambers, oxygen molecules permeate through the specimen into the nitrogen side and are taken to the coulometric sensor where proportional electrical signals are generated. The oxygen transmission rate is then obtained by analyzing and calculating the signals. For package samples, high purity nitrogen flows inside the package, and oxygen or air flows outside.
