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.

The Permeability of Building Materials

The Versaperm WVTR Meter is unusual in that it can measure very thick samples for the WVTR permeability of a variety of building materials. Using the standard flat sample chamber, we can measure up to about 50mm thick samples. This is sufficient for most laminates, timber, felts, films and other materials used in the building industry.

Building Materials

 

However, we also have a number of non-standard chamber configurations which can be used to measure the permeability of almost any thickness of building material. We also have jigs which are used to measure adhesives, mastics and other building sealing materials for leakage rates.

Samples of building materials for permeability testing should ideally be 15 cm x 15 cm (6 inch x 6 inch) or larger, but smaller samples can also be used if required. Customers should also advise if there is a specific orientation required during testing, i.e. if one side is corrodible< in high humidity, or if the vapour barrier is unidirectional.
