With worldwide sales of wound dressings alone now
reaching around $3.3 billion globally there has never
been so great a need to check that the packaging does its
job. It usually needs to allow high temperature steam

The critical factor is the packagings vapour
permeability. Versaperm, a world leader in water vapour
permeability has launched an entirely new instrument to
measure this both quickly and accurately.
The Versaperm WVTR (Water Vapour Transmission) MK VI
meters highly automated computerised control can
cope with several samples at a time - and still give a
reading in as little as 30 minutes for some materials.
The conventional gravimetric measurement technique takes
several days and gives significantly less accurate /
Additionally, the instrument can be configured to measure
the diffusion rates of most gaseous elements (water, O2,
CO2 etc). The MK VI needs very little re-calibration and
requires, at most, minimal training to give results that
can be accurate to better than one part per million (with
some samples a few parts per hundred million).
Sensitivities are typically in the range 0.05 -
The company also operates a laboratory service to measure
permeability for companies where the volume or logistics
of measurements does not demand a dedicated instrument.
