Product catalog summary
Introduction
Labthink Instruments Co., Ltd. offers the OX2/230 Oxygen Transmission Rate Tester, a professional device designed to measure the oxygen transmission rate (OTR) of flexible barrier packaging materials. This instrument is crucial for ensuring the protective quality of packaging materials like plastic films and aluminum foils, which prevent oxidation of packaged contents.

Specifications and Features
The OX2/230 is designed according to ASTM D3985 standards and uses a coulometric sensor to measure OTR. It operates by flushing nitrogen through a chamber containing the film sample, with oxygen on the opposite side. The rate at which oxygen permeates the film is measured by the sensor.
  • Controlled by computer with professional software.
  • Stores previous testing data for reference and comparison.
  • Adjustable testing environment for temperature and humidity.
  • Features three independent testing cells, enhancing efficiency and accuracy.
  • Connectable to nine satellite systems for extended testing capabilities.
  • Reference films available for calibration and comparison.

Technical Specifications
  • Test Range: 0.01~6500 cm3/m2·d (standard), 0.07~65,000 cm3/m2·d (optional).
  • Resolution: 0.001 cm3/m2·d.
  • Temperature Range: 15°C~55°C with ±0.1°C accuracy.
  • Humidity Range: 0%RH, 35%RH~90%RH, 100%RH with ±1%RH accuracy.
  • Test Gases: Oxygen and air.
  • Specimen Thickness: ≤3 mm.
  • Instrument Size: 690mm x 350mm x 360mm, Net Weight: 70kg.

Applicable Standards
The OX2/230 complies with several standards, including:
  • ASTM D3985
  • ASTM F2622
  • ASTM F1307
  • ASTM F1927
  • ISO 15105

Oxygen Permeability Tester of Contact Lens-1

Oxygen Transmission Rate Tester Plastic films and aluminum foils are most used as packaging because they have a good oxygen barrier property to protect the content in the packages from being oxidized by the oxygen in air during its shelf life. Labthink OX2/230 Oxygen transmission rate tester is a professional instrument to measure oxygen transmission rate (OTR) of flexible barrier packaging materials. It is designed according to ASTM D3985 Standard Test Method for Oxygen Gas Transmission Rate through Plastic Film and Sheeting Using a Coulometric Sensor. Using this 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. This oxygen transmission rate tester is applicable in oxygen transmission rate testing of Plastic films, high barrier materials, sheeting, laminated films, foils, paper and paper board, plastic tubes and bottles. OX2/230 oxygen transmission rate tester has the following unique features: Controlled by computer with professional software
