Medical Dressing Oxygen Permeability OTR Measuring Instrument

Product catalog summary

Overview
The C230G Oxygen Transmission Rate Test System is designed to measure the oxygen transmission rate of barrier materials using the coulometric sensor method, conforming to ASTM D3985 standards. It is suitable for materials with high and medium barrier properties and is applicable across various industries including food, pharmaceuticals, and electronics.

Key Features

High Precision: Features a patented integrated test block with advanced hydrodynamic and thermodynamic design, ensuring precise temperature control and stability.
High Efficiency: Capable of testing three identical or distinct specimens simultaneously, increasing throughput and reducing the need for multiple instruments.
Labor Saving: Automatic control of temperature, humidity, and flow rate minimizes manual intervention and potential errors.
Simplified Operation: Equipped with a 12” touch-screen pad and optional DataShieldTM software for efficient data management.

Product Features

Integrated Testing Block: Supports simultaneous testing of three samples with improved measurement accuracy.
Automatic Control: Maintains stable test conditions through automatic temperature and humidity adjustments.
User-oriented Service: Offers customization services for non-standard specimens and packages.

Test Principle
The system measures oxygen permeability by mounting a specimen between two chambers, one with oxygen and the other purged with nitrogen. The oxygen permeates through the specimen, and the rate is determined by analyzing the electrical signals generated by the coulometric sensor.

Test Standards
The system complies with several standards including ASTM D3985, ASTM F1307, and others.

Applications

Basic Applications: Suitable for films, sheeting, and various packaging materials.
Extended Applications: Includes testing of closure systems, solar back-sheets, plastic tubes, blister packs, and more.

Technical Specifications

Test Range: 0.005~200 cm³/(m²·day) for standard tests.
Resolution: 0.0001 cm³/(m²·day).
Test Temperature: 10~55°C with ±0.2°C accuracy.
Test Humidity: 0% to 100% with ±1% accuracy.
Additional Functions: Options for package testing, DataShieldTM, and compliance with CFR21 Part11.

Note: Specifications are subject to change without notice, and Labthink reserves the right for final interpretation and revision.

Medical Dressing Oxygen Permeability OTR Measuring Instrument-1

C230G Oxygen Transmission Rate Test System C230G Oxygen Transmission Rate Test System is designed and manufactured based on the coulometric sensor method (aka. equal pressure method) and conforms to ASTM D3985. This instrument can be used to measure the oxygen transmission rate of barrier materials with high and medium barrier properties with high accuracy and high efficiency. The instrument features Labthink’s patented design of integrated test block consisting of three permeation cells. Equipped with a high precision coulometric sensor and Labthink’s professional computer-controlled system, the instrument can regulate and control the temperature, humidity and flow rate precisely, guaranteeing high sensitivity and excellent repeatability of test results. C230G is applicable to the determination of oxygen permeability of plastic films, sheeting, paper, and other packaging materials used in food, pharmaceutical, medical apparatus, consumer products, photovoltaic and electronic industries, etc. Optional accessories extend the capability to testing complete packages and systems such as bottles, pouches, cartons, blister packs, tubes and more. High Precision • Patented integrated test block with advanced hydrodynamic and thermodynamic design • Labthink’s proprietary thermostat technology ensures that the test block is precisely temperature controlled and remains stable throughout the test. • Temperature and humidity sensor for independent monitoring of test cells High Efficiency • Three identical specimens can be tested simultaneously, which meets the requirements for parallel test. • Three distinct specimens can be tested under the same testing condition, delivering higher throughput while reducing the number of instruments required. Labor Saving • Automatic temperature and humidity control eliminate the need for operator monitoring and adjustment. • Automatic flow rate control ensures constant flow during the testing process and minimizes any errors caused by an unstable flow rate. • No need to verify the system using different reference film for different testing range. Simplified Operation • 12’’ touch-screen pad powered by Windows™ 10 operating system • Fast automatic testing process • Optional DataShield™ software and accessories for automatic data management Product FeaturesNote3 • New Generation Integrated Testing Block Labthink Instruments CO., Ltd. 144 Wuyingshan Road, linan, P.R.China (250031) Phone: +86-531-85068566 FAX: +86-531-85062108 Labthink International, Inc. 200 River's Edge Drive, Medford, MA, 02155, U.S.A.
