Aquadyne™ DVS-1, DVS-2, DVS-2HT


Gravimetric Water Vapor Sorption Analyzers

Water content, water sorption kinetics, and percent water uptake are all characteristics of interest to material scientists. Water sorption behavior plays an important role in the development and use of many common and advanced materials. Some examples include :

.     Stability of pharmaceutical excipients and drug actives

.     Drying and storage of grains

.     Texture and shelf life of food products

.     PEM fuel cell components

.     Mortar, grout and other cementitious materials

.     Paper and coatings

.     Hydrophobic surface treatments

.     Microporous and nanostructured carbons
