Permeability leader Versaperm has introduced a new dual multi-chamber instrument to measure the water vapour permeability of pharmaceutical packaging, such as blisters, to a few ppm or better.

Packaging plays a critical role with pharmaceuticals, particularly as the efficacy of many drugs and compounds depends decisively on their exposure to water and water vapour. Good packaging prevents the drug from harm, contamination, and reduced potency.


Versaperm’s, new 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 new MKVI WVTR meter can measure the water vapour permeability of almost any material and unlike conventional gravimetric measurements which take days or even weeks, it can produce results in as little as 30 minutes. This eases the never-ending quest for effective products with new marketing and technical features.

The new instrument offers highly automated computerised control and can be configured to cope with several samples at a time, giving results that can be accurate to a few part per million (with some samples a few parts per hundred million).

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