Labthink-See the Wisdom From the Details---See Details of i-Oxtra 7700 Oxygen Transmission Rate Testing System
With the national quality standards for packaging materials has been improving steadily, the major Quality inspection institutions and enterprises had more strict requirements on the detection accuracy and time, Computer-controlled automatic testing equipment had become an important tool for routine testing. Labthink International,Inc. had engaged in the research for packaging material testing and the transformation of scientific achievements for ten years and now had spread for more than 40 countries and regions.
i-Oxtra 7700 oxygen transmission rate testing system is the featured product of labthink oxygen barrier series instruments, which can be used in oxygen transmission rate testing of plastic films, high-barrier materials, solar backsheet, sheets, aluminum laminated films, co-extrusion films and packaging containers.The product had powerful functionCflexible expansion and delicate details, which is full of inspiration and innovation of wisdom.
1. Double support of diagram and container had diversified the testing objects.
In the oxygen barrier property evaluation system of packages, the oxygen transmission rate of packaging materials and containers are two most instructive evaluation indexes,in comparison, the latter is more important. For even the packaging material itself had higher barrier properties, after the multiple procedures of squeezing, pressing, compositing, its whole barrier properties will change. Labthink had designed a series of container testing accessories according to ASTM F1307 which had requirements of oxygen transmission rate of container, it can realize the oxygen transmission rate test through accessories attachment.
2. Patented structure reduces system space occupancy, improve testing efficiency
Three cavities into one integrated block is one patent design of Labthink. Viewed from the exterior, the testing cavity is increased from single cavity to three cavities and appeared as three-sides of stereo structure, the design ,on one hand, it can make three independent samples test simultaneously and improve the testing efficiency, on another hand, it accomplishes the first cavity integration structure, which greatly reduced space occupancy of system. Deep inside, close integration of three cavities makes internal line decreased a lot and reduce the possibility of gas leakage to a certain extent. Meanwhile, it is easy to maintain the uniformity of temperature and humidity and guarantee the testing accuracy on the whole.
3. Strong and flexible expansion capability can satisfy clients’ requirements in different levels
The departments of Quality Inspection and Drug Administration had heavy testing duties, testing efficiency is almost the first problem to face and solve. Labthink can supply the patent structure of three cavities into one integrated, host-satellite mode is a creative solution concerning this issue. The so-called host-satellite mode, refers to one host tester can connect nine satellites and can easily test 30 samples at the same time. In addition, the satellite type can be configured according to clients’ needs, such as oxygen transmission rate tester or water vapor transmission rate tester, which is convenient to monitor different testing process and data in different content. The client has many materials such as plastic films, sheets, composite materials, aluminum laminated films, which all have different barrier properties. Every instrument has certain testing scope, once it encounters the materials with large transmission rate, most instruments will face the danger of outrange. Labthink supply the new expansion technology named “MASK,” which adopts one PVC membrane material with high barrier, it can make oxygen transmission rate conform to the testing scope by narrowing testing area.
4. Delicate details promote testing accuracy
Theoretically speaking, in barrier testing the two sides of sample reached to permeation balance can be viewed as the the end of test. But most samples, especially new materials, of which property is unknown for inspectors, it is difficult to judge when and what state is penetration balance, and if the judge can relate to the accuracy of the results scientifically and tightly.
Labthink had set up three judgment modes to instruct client to end up the experiment. The proportional mode is the suggested mode of Labthink. In the same time interval, if the gas transmission variation is less than a preset percentage to determine whether to stop the experiment or not. And there are also cycle mode and manual mode to choose.
Another highlighted detail of i-Oxtra 7700 is the unique design of Catalytic deoxidization device and temperature controlling apparatus. Catalytic deoxidization device had specific catalyst, react with the residual oxygen in carrier gas and produce other compounds which don’t affect the experiment and reach better deoxidization effect and reduce the test error, temperature adjustment is one function for part of the user to simulate the testing environment. Labthink developed one temperature-control container testing apparatus to be auxiliary accessories and the users can add according to the needs.
Great achievement comes from little, perfect comes from details. Labthink will firmly adhere to the working philosophy, continuously inject hard work, wisdom and innovation factors, open the new situation of testing technology.
