Valves, tubing and filters are amongst the most widespread items in machinery, factories and products – from the largest valve on an oil pipeline to the smallest one-way degassing filter on a pack of coffee, they all have one thing in common – a tendency to let gases and liquids seep into the wrong places!  Versaperm has one of the answers – the Versaperm VI.

Surprisingly there are actually two completely different problems, leakage and permeability – and permeability is by far the most insidious and hardest to track down.   Liquids are relatively easy to contain, but in their gas state they can simply permeate through materials.  For example products that include cellulose may be be an almost perfect barrier to water – but they let water vapour through almost as if they weren't there.

Water vapour has become the world's most damaging contaminant which, in the UK alone, causes billions of pounds of damage every year,

The Versaperm VI meter is a highly sensitive and accurate system for measuring this permeability (it optionally works for water vapour or almost any other gas) and it has a truly enormous range of applications.

The equipment is both precise and simple to use.  In some cases it can produce results in as little as 30 minutes, as opposed to the days or even weeks with traditional gravimetric testing. Accuracies are typically in the parts per million range, (parts per billion with some gases) and the equipment is ideal for general testing as well as QC, lab and development work.

As well as manufacturing the instruments, Versaperm offers a permeability laboratory service for companies that only need to test samples on an irregular basis.
