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.

Measuring the permeability of Mastics and adhesives

Measuring the vapour permeability of a mastic or adhesive (or seal) is simple with our new permeability measurement equipment, although sometimes it requires a specific additional jig.

The equipment quickly and reliably measures the permeability and diffusive flow of vapours across the mastic, seal or adhesive barrier - which can be a sample of the mastic or adhesive or a component with the mastic or adhesive in place,

Our new permeability meter allows you to measure vapour permeability for a wide range of gases, including O2, N2, He, Hydrocarbons gases and water vapour.

 

 Permeability measurement o mastic or seal

The permeability meter needs no re-calibration, is simple to use and can achieve accuracies of better than one part per million (with some samples a few parts per hundred million). 

We also provide a comprehensive permeability testing service.


Laboratory (R&D) permeability testing

An enormous range of Sealants and Adhesives is in widespread daily use.  In many applications and situations one of the critical factors for a mastic or adhesive is its ability to prevent the ingress or exit of water, hydrocarbons (usually in vapour form) or other gases.  This requires a measurement of the permeability the adhesive or mastic – which could be Non Silicon sealants, Expanding PU Foams, Gap filling Adhesive, PU Adhesives, PVA and contact Adhesives, Specialist Tapes,  Acetoxy or a Neutral Silicone.
