Oxygen Transmission Rate Tester (Single Test Cell)

Cost-Effective Oxygen Barrier Testing Solution for Packaging Laboratories

Product Overview

The LabStone OTR-E-11-G Oxygen Transmission Rate Tester is a compact and cost-effective oxygen permeability measurement system designed for laboratories that require reliable oxygen barrier testing without the need for multi-cell high-throughput configurations.

Based on the internationally recognized Coulometric Sensor Method, the instrument accurately determines oxygen transmission properties of packaging materials, pharmaceutical packaging materials, containers and barrier structures.

The single-cell configuration provides an economical solution for routine testing, research projects, incoming material inspection and educational laboratories while maintaining the same measurement accuracy as larger multi-cell systems.

Function：

Determining oxygen permeability characteristics of materials and container.

Suitable for: Film, sheet, container and construction material of plastic, textile, leather and metal.

Working Principle

The OTR-E-11-G utilizes the Coulometric Sensor Method specified in ASTM D3985 and ISO 15105-2.

One side of the specimen is exposed to oxygen or controlled humidity oxygen.

The opposite side is continuously purged with ultra-high purity nitrogen carrier gas.

Due to the oxygen concentration gradient, oxygen molecules permeate through the specimen.

The permeated oxygen is transported to an ultra-sensitive coulometric sensor.

The sensor directly measures oxygen concentration and automatically calculates:

Oxygen Transmission Rate (OTR)
Oxygen Permeability
Barrier Performance Parameters

The direct measurement approach ensures excellent sensitivity and repeatability.

Compliant Standards:

ASTM D3985, ASTM F1307, ASTM F1927, ASTM F2622, ISO 15105-2, JIS K7126-2, GB/T 19789

Designed for Laboratories Seeking High Accuracy with Lower Investment

Not every laboratory requires multiple testing cells.

Many laboratories perform:

Product verification
Supplier qualification
Material certification
Research testing
Educational studies

where a single test station provides the most cost-effective solution.

The OTR-E-11-G delivers professional oxygen barrier testing capabilities while minimizing laboratory investment and operating costs.

Why Measure Oxygen Transmission Rate?

Oxygen is one of the most significant factors affecting product stability and shelf life.

Excessive oxygen transmission can result in:

Food Packaging

Oxidative rancidity
Loss of flavor and aroma
Nutrient degradation
Shortened shelf life

Pharmaceutical Packaging

Active ingredient degradation
Reduced drug stability
Packaging validation failures

Medical Packaging

Product performance changes
Reduced protection capability

Specialty Materials

Barrier performance degradation
Reduced product durability

Accurate OTR measurement is therefore essential throughout packaging development and quality assurance processes.

Typical Applications

Packaging Material Evaluation

Suitable for testing:

PE films
PP films
PET films
Nylon films
EVOH barrier films
PVDC structures
Metallized films

Pharmaceutical Packaging Testing

Used for:

Blister packaging materials
Medical pouches
Pharmaceutical laminates
Drug packaging barrier studies

Supplier Qualification

Evaluate oxygen barrier consistency between different material suppliers.

University Research and Education

Ideal for:

Material science research
Packaging engineering programs
Laboratory teaching
Scientific studies

Third-Party Testing Laboratories

Suitable for contract testing services where throughput requirements are moderate.

Advantages of a Single-Cell OTR Tester

Compared with multi-cell systems:

Lower Initial Investment

Ideal for laboratories beginning oxygen barrier testing programs.

Lower Gas Consumption

Reduced operating costs.

Easier Training

Simple workflow for operators.

Smaller Installation Space

Suitable for compact laboratories.

Same Measurement Accuracy

Uses the same imported coulometric sensor technology found in larger systems.

Function：
Determining oxygen permeability characteristics of materials and container.
Suitable for: Film, sheet, container and construction material of plastic, textile, leather and metal.
Principle:
Coulemeter Sensor method。
Dry oxygen（or with a certain humidity）flows on one side of the specimen, and high-purity nitrogen (carrier gas) flows at a fixed flow rate on the other side; The oxygen concentration difference between the two sides of the specimen drives the oxygen to penetrate from the oxygen side of the specimen to the nitrogen side; The permeated oxygen is carried to the coulometer sensor by nitrogen (carrier gas); The sensor measures the oxygen content of carrier gas and calculates the oxygen permeability of the specimen.
