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 Vapour Permeability of Pharmaceutical and Medical products


Measuring the permeability of medical and pharmaceutical products and equipment can be accurately, easily and quickly achieved with our latest permeability meter. It can measure the permeability of both individual materials as well as finished products.

Permeability plays a major role for medical and pharmaceutical products and is the critical controlling factor in contamination prevention. Also, the moisture that permeates the protective packaging reduces the potency and shelf life of many drugs and compounds. Good packaging prevents the drug, dressing or syringe etc from harm, contamination and reduced efficacy.

 

Our WVTR (Water Vapour Transmission) meter can measure the permeability of both materials and finished packages. These can vary greatly with around 75% of a plastic or laminate’s barrier typically being lost just by forming it into a blister. The meter can be configured to measure the permeability of most of the gases used in the medical field - including Oxygen, CO2, alcohol and anaesthetic gases.

The MKVI WVTR meter can measure the vapour permeability of almost any material quickly and accurately. Conventional gravimetric measurements - which take days or even weeks, can produce results that are often less reliable. Sensitivities are typically in the ppm range (considerably higher in for some materials and gases), where required, flow rates considerably in excess of 3,000g/m2/day can also be measured using alternative techniques.

We also offer a laboratory testing service for companies who test too few samples to make the purchase of equipment viable.

Permeability is the degree to which one substance allows another substance to pass through it. It is often critical in medical and pharmaceutical applications to prevent contamination, for protection, and to extend the shelf-life & potency of drugs or ensure powders do not clog. It is used in the design and manufacture of blister packs, bottles, pill containers, surgical dressings, needles and syringe products.
