Oxygen Transmission Rate (OTR) Tester
Oxygen Permeability Tester | ASTM D3985 & ISO 15105-2 Coulometric OTR Testing
An oxygen transmission rate tester measures the oxygen transmission rate (OTR) of films, foils, and finished packages using the coulometric sensor method. This absolute measurement technique determines oxygen flux directly, providing reliable barrier-performance data for packaging, food, pharmaceutical, and materials laboratories. Also referred to as an oxygen permeability tester, the ToronOTR™ series supports standards-based oxygen barrier testing in controlled temperature and humidity conditions in accordance with ASTM D3985 and ISO 15105-2.
The ToronOTR™ oxygen transmission rate tester range includes a compact single-cell model for entry-level and lower-volume testing, as well as a three-cell configuration designed for increased testing capacity in quality control and research and development laboratories. Both configurations can test flat films and finished packages, allowing laboratories to select a system based on sample requirements, testing volume, and temperature-control needs.
Applications
Oxygen transmission rate testing is used in quality control and research and development to evaluate oxygen barrier performance in packaging materials and finished packages where oxygen exposure can affect product quality, stability, and shelf life.
-
Food and Snack Packaging: Evaluates the oxygen barrier performance of films, laminates, and finished packages designed to help preserve freshness, flavor, and shelf life.
-
Pharmaceutical and Medical Packaging: Tests blister films, foils, pouches, and other packaging materials used for oxygen-sensitive pharmaceutical products and medical devices.
-
Flexible Packaging and Converting: Assesses high-barrier laminates, metallized films, and barrier coatings during material development, process qualification, and production quality control.
-
High-Barrier Film R&D: Characterizes materials such as EVOH, PVDC, and nylon structures where oxygen barrier performance can vary significantly with relative humidity.
-
Finished Package Testing: Measures the oxygen transmission rate of complete packages, including pouches, bottles, and trays, using suitable package testing fixtures.
-
Electronics and Photovoltaic Encapsulation: Evaluates barrier films and encapsulation materials designed to limit oxygen exposure to sensitive electronic components and photovoltaic (PV) devices.
Oxygen Transmission Rate Tester Range
The ToronOTR™ oxygen transmission rate tester range uses a coulometric measurement system for accurate oxygen barrier evaluation and offers different configurations based on testing capacity and temperature-control requirements. The range includes single-cell and three-cell systems, allowing laboratories to select a suitable oxygen permeability tester based on sample volume, throughput, and test conditions.
| Model | Test Cells | Detection Range (Film) | Description |
|---|---|---|---|
| ToronOTR™ 1 | 1 | 0.01 to 6,300 cm³/m²·d | Compact single-cell coulometric OTR tester for entry-level and low-volume labs. Tests films and packages, with optional temperature control. |
| ToronOTR™ 3 | 3 | 0.01 to 6,500 cm³/m²·d | Three-cell coulometric OTR tester with standard water-bath temperature control. Tests three specimens at once for higher-throughput QC and R&D. |
How to Choose the Right Oxygen Transmission Rate Tester
-
For entry-level and low-volume testing: Select the ToronOTR™ 1, a compact benchtop oxygen transmission rate tester with optional temperature control for routine laboratory testing.
-
For higher testing throughput: Select the ToronOTR™ 3, which can test three specimens simultaneously and provide independent results for each test cell.
-
For temperature-controlled testing: The ToronOTR™ 3 features standard water-bath temperature control, making it suitable for applications requiring controlled testing temperatures.
-
For finished-package testing: Both models can be configured with suitable package fixtures for testing pouches, bottles, trays, and other finished packaging formats.
