Versaperm Vapour Permeability measurement

Moisture vapour permeability measurement for medical equipment, QC and the lab

Water vapour is everywhere and creates more problems than almost everything else put together. Yet it is also useful when, as superheated steam it sterilises and purifies. Sometimes it is essential that vapour can flow through a material – for example the packaging on a sterile syringe or bandage, sometimes it must be barred as it degrades drugs (especially in powder form).

The solution is a comprehensive vapour permeability laboratory testing service (and /or equipment) from Versaperm – technology leaders in this complex field.

Versaperm’s service is based on its own advanced design of WVTR (Water Vapour Transmission) meter, which can quickly produce results that are accurate to better than one part per million. The meter is around 100 times quicker, and more accurate than conventional gravimetric techniques.

It can be used on huge range of medical, laboratory and QC materials or enclosures – from foil laminates to inhalers and from paper or plastic packaging through to container seals and technical instruments. It can also provide measurements of substances that might otherwise be decomposed by normal water content measuring techniques.

Sensitivities are in the range 0.05 – 3200g/m2/day .
