LABTHINK OX2/230 OXYGEN TRANSMISSION RATE (OTR) TESTER ---measure O2 transmission rate through plastic films and flexible packaging When packaging oxygen-sensitive food products, such as meat, maintaining the product’s freshness and shelf life is of high concern. The atmospheric conditions inside of a package contribute directly to the success or failure of preserving perishable goods. Therefore, breathable packaging is widely used because of its precise oxygen transmission rate required for each individual product. Oxygen transmission rate (OTR) is a calculated measurement of the amount of oxygen gas that, over a given period of time at a steady rate, passes through a substrate. Oxygen transmission rate are used to give value to the oxygen barrier capabilities of a flexible packaging film. The OTR testing process at Labthink Instrument Company is based on ASTM D3985: Standard Test Method for Oxygen Gas Transmission Rate Through Plastic Film and Sheeting Using a Coulometric Sensor. Using OX2/230 oxygen transmission rate tester, nitrogen is flushed through a chamber where the film sample has been placed. The film in the chamber separates the nitrogen on one side from the oxygen on the other side. Oxygen molecules move through the film to the low pressure side, with the film barrier determining the rate of the oxygen transmission. A coulometric sensor placed on the outgoing nitrogen side measures this rate of oxygen transmission. Contact: Yarina Gao Email: trade5@labthink.cn Phone:086-531-85060139
