About Versaperm

Versaperm manufactures gas permeability testing equipment, offers a comprehensive permeability testing service and a materials consultancy. These are used to measure gas permeability and leakage, important in medical and pharmaceutical packaging, foils and films, coatings, food and confectionery packaging and contents, and many other applications.

Instruments

Versaperm designs and manufactures instruments to meet each customer’s needs. Instruments are typically be based on a modular MkVI design.

Testing Service


Our laboratory testing service has over 30 years experience to enable us to choose the best technique to measure your sample's permeability both quickly and accurately.

 

Sensors

Our diverse and growing range of sensors are based on fundamentally different and divergent physical principals. The choice of the right sensor for an application is critical in the successful deployment of the equipment. We are not tied to a sensor manufacturer.

Gases / Vapours

At Versaperm we can measure the permeability for almost any gas / vapour including water vapour, Oxygen, CO2 Hydrogen, Helium, Nitrogen and Hydrocarbons.

Applications

Consultancy

Our Consultancy division combines our theoretical and practical Permeability skills in instrument design and manufacture. Permeability Consultancy

Carbon Dioxide (CO2) Permeability
testing


Commercial measurement of Carbon Dioxide permeability rates is widespread, though it is particularly import for carbonated drinks containers, which are commonly made from polyethylene terephthalate (PET) as this material has good barrier properties against both oxygen and carbon dioxide.

Versaperm can measure the CO2 (and other gas) permeability of bottles or containers that are filled with fizzy drinks. It can also measure the permeability of the material in flat sample format. These two measurements are unlikely to be identical due to the thermoforming process, which can increase permeability by several hundred percent!

Typically a specimen is placed in the measurement chamber which separates the two sides of the material. One of these is exposed to a an inert atmosphere (e.g. a constant flow of nitrogen) while the other is exposed to CO2. Once a steady state has been achieved the amount of oxygen in the nitrogen is measured with any one of a number of sensors (depending on the sensitivity required) and the permeability is simply read off the screen.

Carbon Dioxide Permeability

With the Versaperm meter low permeation rates can be measured quickly and accurately.

The Carbon Dioxide sensor used depends on the choice of the customer. We use a wide variety of sensors, sourced from market leaders around the world, and are able to build an instrument around a sensor of the customer's choice.

We customise each instrument to meet the range required by the customer's application.
