| Quick ROI
Sending materials to third-party labs for isotherm analysis or shelf life testing is far from economical. Save money and shorten R&D timelines by doing in-depth analysis in-house. |
Glove-friendly buttons
Skip the finicky, unresponsive touch screens. VSA’s tactile and durable buttons make it easy to manage and start tests, even while wearing gloves or other PPE. |
In the lead for 40 years
Since our founding in 1983, we’ve stayed laser-focused on moisture management science – and built the industry’s largest body of expertise on the topic. |
Highly secure
Connect and sync if you need to. Stay offline and locked down if you don’t. Aqualab devices can sync data to any smart device – without being hamstrung if policies prohibit connectivity. |
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.

| Double the insight
While average instruments only use the DVS method, the 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. |
