Moisture Research in a Box
For food or pharmaceutical scientists, moisture sorption data
can make or break a product. The AquaLab Vapor Sorption
Analyzer (VSA) introduces simplicity, control, and affordability
into the process of gathering moisture sorption isotherm data.

Simplicity
Using isotherm data to improve product performance should be
part of your job. Spending countless hours on your lab
instrument shouldn't be. With the AquaLab VSA, it takes about
5 minutes to set up a test. Once you tell the AquaLab VSA the
humidity levels and times you'd like to use, just put the sample
into the instrument and walk away. The data from your test
are automatically recorded and sent to your computer.
Control
The AquaLab VSA is the first instrument that allows you to
measure both DVS and DDI isotherms on your product. In simple
terms, DDI isotherms are extremely high resolution, allowing you to
pinpoint critical moisture ranges for product quality. DVS
isotherms allow you to study kinetics, or how long it takes for
something to happen. For example, how long it would take for
a potato chip that starts at 0.15aw to lose its crispness in air
that's at 80% relative humidity. AquaLab VSA can measure
isotherms by constantly introducing saturated or dry air into the
chamber (DDI), or it can control humidity at a specific level,
raising and lowering RH when equilibrium has been reached
(DVS).
Affordability
Costing 50-80% less than other moisture vapor sorption
analyzers, the AquaLab VSA can fit into an R&D budget.
Its affordability results from the new approach we've taken to DDI
and DVS isotherms. AquaLab VSA gets the the same or better
performance as other models, while putting isotherm science within
financial reach for scientists.
