AND RUBBER INSTRUMENTATION
Fast accurate measurement of the Worlds most
damaging contaminant and its most beneficial!
Limited, a world leader in water vapour permeability is
launching an entirely new instrument for the fast and
accurate measurement of water vapour permeability
in plastic and rubber
materials, products and containers.
The majority of films, plastics, coatings and polymers
are impervious to liquid water, but many of them allow
water as a vapour vapour to pass straight through. This
can cause widespread problems from packaged drugs
loosing effectiveness through to equipment failing, or
cornflakes going soggy.
Water is both the worlds most damaging contaminant
and its most beneficial substance. Water vapour is both
omnipresent and highly invasive.
materials with inappropriate vapour permeabilities costs
the UK alone considerably over £100M every year and
needlessly reduces the active life and effectiveness of a
huge range of preparations.
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 conventionally gravimetric measurement technique
takes several days and gives significantly less accurate
/ reproducible results.
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 - 3200g/m2/day.
wide variety of options is available, depending on the
specific applications, but both single and multi-sample
systems, plus a range of measurement chambers and sensors
can be supplied for testing samples from the size of a
thimble up to a pallet load and beyond.
well as vapour transmission, the equipment can be used to
measure the Equilibrium Relative Humidity (ERH) of
substances - that might otherwise be decomposed by normal
water content measuring techniques. Additionally the
instrument can be configured to measure the diffusion
rates of most gaseous elements (water, O2, CO2 etc).
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.
