MultiPerm O2-CO2: O₂ and CO₂ Permeability Tester
Single or Dual Cells
O2 and CO2 Permeability Tester with Integrated Temperature and Relative Humidity Controls.
O₂ and CO₂ Permeability Tester
MultiPerm O2-CO2 is a permeability tester designed to determine oxygen and carbon dioxide transmission through films, barrier materials and multilayer structures.
The instrument measures OTR (Oxygen Transmission Rate) and CO₂TR (Carbon Dioxide Transmission Rate) with controlled temperature and relative humidity conditions.
Depending on the model, the one- or two-cell configuration allows testing of one or two samples, either simultaneously or sequentially. MultiPerm O2-CO2 is suitable for characterizing plastic films, barrier films, laminates, metallized materials and co-extruded structures.
It is designed for research and development, material qualification and quality control laboratories, particularly in the food packaging, beverage, pharmaceutical and electronics industries.
What Does MultiPerm O2-CO2 Measure?
MultiPerm O2-CO2 measures the transmission of two gases through packaging materials and barrier films.
- Oxygen transmission rate (OTR): evaluates the amount of oxygen passing through a material under specified test conditions.
- Carbon dioxide transmission rate (CO₂TR): evaluates the amount of carbon dioxide passing through a material under specified test conditions.
These measurements help characterize the barrier performance of materials and compare different films, laminates and multilayer structures.

Materials That Can Be Tested
MultiPerm O2-CO2 can be used to characterize different types of materials, including:
- Plastic films
- Barrier films
- Multilayer films and laminates
- Metallized films
- Co-extruded structures
- Flexible packaging materials
The instrument supports material characterization and comparison during development, qualification and quality control activities.
Applications of MultiPerm O2-CO2
Food and Beverage Packaging
Oxygen and carbon dioxide transmission measurements help evaluate packaging barrier performance and support the selection of materials for food and beverage applications.
Plastic Films and Barrier Materials
OTR and CO₂TR testing helps characterize films and compare materials with different barrier properties.
Multilayer Films and Laminates
The instrument supports the evaluation of multilayer structures and laminates designed to provide specific gas barrier performance.
Pharmaceutical Packaging
Gas transmission measurements help characterize packaging materials when barrier performance is an important part of material qualification.
Containers and Formed Packaging
Permeability testing can support the evaluation of suitable packaging materials and structures, depending on the sample type and available test configuration.
Research, Development and Quality Control
MultiPerm O2-CO2 can be used in laboratories working on material development, incoming material qualification, comparative testing and quality control.

NORMS: MultiPerm complies with DIN 53380-3, ASTM D3985, F2622, F1927, F1307, JIS K-7126, ISO 15105-2 for OTR measurements, and ASTM F2476 for CO2TR measurements.
MultiPerm is the only instrument on the market with patented technology that allows simultaneous barrier measurements for two different gases on one or two distinct samples. MultiPerm comes equipped with two sensors, which can be selected from oxygen, carbon dioxide, and water vapor.
This instrument is designed to measure the permeability of plastic films, single-layer or multi-layer barrier films, metallized films, or those with special surface coatings, laminated or co-extruded, predominantly used in the food, beverage, pharmaceutical, and electronics industries.
In addition to measuring the permeability of thin films, MultiPerm, equipped with modular accessories, can perform analyses on formed containers such as bag-in-box, PET bottles, and various other receptacles.
MultiPerm represents the ideal solution for companies that produce or utilize barrier packaging, offering the highest performance in a single instrument at a competitive price.
The advanced MultiPerm ExtraSolution® software ensures maximum operational simplicity. Users can start, monitor, and complete the measurements simply by selecting the appropriate tab in the software, which simultaneously and/or sequentially manages the analyses on one or two different samples (depending on whether it is a single or dual-cell model) for two different gases.
Choosing MultiPerm means making an intelligent choice that reduces costs and optimizes space. Why buy two different instruments when you can have everything in one with MultiPerm?
