AQUALAB VSA Complete moisture sorption isotherm analysis Description:

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. AQUAL AB 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 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.

Double the insight

While average instruments only use the DVS method, Aqualab VSA delivers DVS isotherms plus DDI isotherm curves. DDI curves make never-before-seen details visible in your product and allow more precise formulation, more accurate predictions, and more complete product knowledge.

Moisture Analysis Toolkit

The VSA comes with intuitive, full-featured modeling software. The Moisture Analysis Toolkit helps you turn your data into solutions using research-tested predictive models. It's every model you need in one place, in a simple-to-use program.
