Description
The AQUALAB VSA delivers fast, high-resolution graphs that change the way you understand your product and DVS isotherm interpretation.
Dual testing modes and sophisticated modeling software turn your data into the solutions you need to manufacture, monitor, store, and ship a great product.
Solve your most pressing problems with high-resolution moisture sorption isotherms. Determine shelf life, choose packaging, erase caking and clumping, and much, much more.
Precision in every point.
Newer DVS (Dynamic Vapor Sorption) methods are fast – but expensive and less data-driven. Old-school isotherm creation requires acres of desiccators and months of manual data collection. AQUALAB VSA delivers both DVS isotherms and truly dynamic high-resolution DDI isotherm curves – with hundreds of points, instead of just five or six. All within 48 hours. Solve problems like caking and clumping, matching the excipient to the API, and choosing the correct packaging.
Higher resolution, less time.
The VSA’s groundbreaking design uses a fast water activity sensor combined with a very precise scale to create isotherm graphs dynamically. It passes humidified air over samples and measures both weight and water activity simultaneously. It then creates sorption and desorption isotherm curves with hundreds of points, instead of just five or six. And it does so in only a couple of days (approximately 48 hours), instead of a couple of months.
