OX2/231 Oxygen Permeability Tester

Model: OX2/231

Brand: Labthink – China

OX2-231-2014b

OX2/231 is based on the equal pressure method, and is professional applicable to the determination of oxygen transmission rate of film and package products, including plastic films, composite films, sheeting, plastic bottles, plastic bags and other packages.

Features:

 

  • Tests 3 equivalent specimens at one operation and exports test results in average value
  • 2 test modes for both films and packages, and accessories for package test are available for customization
  • Equipped with constant temperature and humidity control devices (optional parts) to meet different test requirements
  • Reference film for fast calibration to ensure accurate and universal test data
  • The instrument is controlled by micro-computer with LCD, menu interface and PVC operating panel, which could conveniently export test data, test results and test curves
  • Test data could be automatically and safely saved by the function of power failure protection
  • Micro-printer and standard RS232 port for convenient data output and transfer
  • Supports LystemTM Lab Data Sharing System for uniform management of test results and test reports

Principle

The pre-conditioned specimen is mounted between the upper and lower chambers at ambient atmospheric pressure. One chamber contains oxygen 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 flows outside.

Standards

This test instrument conforms to the following standards:
ISO 15105-2, GB/T 19789, ASTM D3985, ASTM F2622, ASTM F1307, ASTM F1927, JIS K7126-2, YBB00082003

Applications:

This test instrument is applicable to the determination of oxygen transmission rate of:

 
Basic Applications
  • Films
    Including plastic films, plastic composite films, paper-plastic composite films, coextruded films, aluminized films, aluminum foils, aluminum foil composite films and many others
  • Sheeting
    Including various sorts of engineering plastics, rubber and building materials, e.g. PP, PVC and PVDC
  • Packages
    Including plastic, rubber, paper, paper-plastic composite, glass and metal packages, e.g. Coke bottles, peanut oil packages, Tetra Pak materials, vacuum bags, metal three-piece cans, plastic packages for cosmetic, soft tubes for toothpaste, jelly and yogurt cups
Extended Applications
  • Package Caps
    Test seal performance of different package caps
  • Solar Back-Sheets
    Including solar back-sheets
  • Plastic Pipes
    Including various sorts of pipes, e.g. PPR
  • Blister Packs
    Test oxygen transmission rate of the whole blister packs
  • Contact Lenses
    Test oxygen transmission rate of contact lenses in usage situation
  • Fuel Tanks of Cars
    Plastic fuel tanks are widely used in cars for its light weight, buffering vibration and easy molding characters. But its fuel permeability is the most essential factor, this instrument can be used to test permeability of plastic fuel tanks
  • Battery Plastic Shell
    Battery electrolyte is protected by the plastic shell from outside environment. Battery service life is directly dependent on its oxygen permeability. This instrument can be used to test oxgyen transmission rate of battery plastic shell
  • Red Wine Bottles
    Test oxygen transmission rate of red wine bottles
  • Biodegradable Films
    The oxygen transmission rate is an essential factor that affects biodegradable film properties and further development
  • Soft Plastic Infusion Bottles
    Oxygen is the main factor that leads injection to deterioration. It will be very important to lower oxygen content of infusion bottles
  • Warm Paste Packages
    Once touched with oxygen before usage, warm pastes will lose efficacy, they should be placed in vacuum packages. So it is necessary to test the oxygen transmission rate of warm pastes packages.
