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. Before you learn about our product, you might be interested in:
As for the product itself, here are the key points:
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.
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).
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 technology within financial reach for scientists.
ecagon Devices, Inc. - Makers of the AquaLab Line of Products
Decagon designs, manufactures, and markets scientific instruments. The AquaLab division focuses on measuring total moisture (water activity, moisture content, and moisture sorption isotherms) in foods, pharmaceuticals, and other products.
Decagon's instruments are used by more than 80% of the top 100 foods companies. They're also used by pet food manufacturers, pharmaceutical companies, universities, government agencies, research and testing labs, and in other industrial applications.
When Decagon was founded in 1983, water activity was still an emerging concept in the food industry. Now most companies measure water activity to assure the safety and quality of their products. The speed and accuracy of the AquaLab series of water activity meters has become an industry standard.
Interesting Decagon Facts:
Decagon has done many novel water activity projects for manufacturers, including measuring the water activity of cupric oxide in air bags and determining the moisture content of plastic pellets.
Decagon got a peek into military life when the Department of Defense Combat Feeding Program used water activity to make sandwiches with a three-year shelf-life for MREs.
Decagon also makes instruments for environmental research. (Visit our environmental science division at www.decagon.com).
Decagon built a thermal and electrical conductivity probe for NASA's Phoenix Scout Lander mission to Mars. The probe successfully gathered thermal and electrical properties data in addition to measuring atmospheric humidity and wind speed.
Decagon is located in Pullman, Washington, home of Washington State University.
Quality Management at Decagon
In order to provide timely feedback to the high volume of vendor surveys and evaluation requests Decagon Devices, Inc. receives, Decagon has created a Quality Survey Response for our customers. We have designed this response to fit the majority of the questions we are asked in regards to our Quality Management System, ISO9001:2008 registration and calibration services.
