…that moisture doesn’t affect our pharmaceutical products.
Water vapour can be the omnipresent
curse or the saviour of the pharmaceutical industry. It makes powders
clog aerosols, it permeates through packaging, plastic and unitary dose
blister packs and causes preparations to loose potency. Yet without it,
producing sterile products such as syringes, plasters and bandages would
be much harder.
The key lies in the way vapour
permeability works - which often seems counter-intuitive as some materials
are a total barrier to water but allow water vapour to pass through virtually
unhindered. The solution is the Versaperm WVTR meter, which can quickly
and accurately measure the water vapour permeability of most materials,
seals, drug delivery systems, films, coatings or containers. So problems
can be stopped before they start.
Versaperm Limited is a world
leader in water vapour permeability measurement and its WVTR meter can
handle several samples at a time - often give a reading in as little as
30 minutes. Conventional gravimetric measurement techniques take several
days and are significantly less accurate.
The meter is easy to use and
gives a series of digital readouts that can be recorded or simply read
off the LCD screen. It needs no re-calibration and requires, at most,
minimal training to give results that are accurate to better than one
part per million (with some samples a few parts per hundred million).
Sensitivities are in the range 0.05 – 3200g/m2/day.
Versaperm also offers a next
day testing service.
