infusion bag IV bag Oxygen barrier rate (OBR) testing equipment is mainly used for Oxygen barrier rate (OBR) measurement of infusion bag film materials, infusion bags or the whole infusion bottles. Equal pressure method and differential pressure method, the two methods for Oxygen barrier rate (OBR) testing can both test the Oxygen barrier rate (OBR) of films and of the whole infusion bags and bottles. Those two methods have their respective advantages: differential pressure method has no requirements for testing gas, and can be used to test the barrier rate (OBR)of any gas. Thus, this method can be used to test nitrogen barrier rate (OBR) without further costs. However, this method is still at the initial stage in package testing. On the other hand, equal pressure method has become mature both for film testing and package testing. Yet, there exist limitations for testing gas.

Nitrogen barrier rate testing for infusion bag film material has always been a hotspot. At present, the testing can only be done with differential pressure testing instruments. However, some holds that both nitrogen and oxygen belong to the normal inorganic gases, and there would be some kind of ‘interior’ combination for oxygen barrier rate (OBR)and nitrogen barrier rate of the same specimen; thus, nitrogen barrier rate can be estimated and assumed from the oxygen transmission rate with simple proportional relationship. However, great amount of testing data has proved this estimation is low in accuracy, and would bring hidden danger to the material selection.
