Permeability leader Versaperm has introduced a new multi-chamber instrument for medical manufactures to measure the water vapour permeability of sensitive medical packages such as blister packs, sterile packs, syringes etc - to a few ppm or better. Water vapour is everywhere and causes more problems than most other things put together - costing the UK over £100M each year. y.


Versaperm’s, new WVTR (Water Vapour Transmission) meter can measure the permeability of both individual materials as well as finished packages or product. Finished products can vary greatly from predicted values based on the materials used – with manufacturing processes such as forming typically reducing permeability by 75%.

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

The meter offers highly automated computerised control and is capable of coping 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.
