Would you like to save time and resources while running FSO2 (Free Sulfur Dioxide) checks on your wines in the cellar? 

Post-harvest, individual barrels, barrel lots and tanks require tracking of free sulfite, total sulfite, and acetic acid, in addition to glucose/fructose, organic acids and polyphenolics. BioSystems Free sulfite analysis kit is a fast, reliable and robust system that allows you to perform concurrent multiparametric analysis on our automated analyzers. So not only can you monitor free sulfite, but you can perform comprehensive, simultaneous QC with automation from less than a single 2 mL sample cup. All the user needs to do is load the sample, select the desired analytes, press run, and then continue onto other tasks while the instrument works unmonitored!  

Biosystems Free sulfite analysis kits were validated by partnering with wineries and reference laboratories around the world. This method has shown excellent performance compared with Aeration-Oxidation (A/O), within 2ppm of the desired target.   

Keeping FSO2 levels within 2ppm of the desired target, known as the Acceptable Overage, is critical for consistency and quality control. This precision ensures that winemakers can maintain the desired SO2 levels consistently across large batches and over time, contributing to the overall quality, stability, and longevity of the wine. 

We offer 30 plus enzymatic and colorimetric kits for organic acids, sugars, sulfites, phenolics and more! We have US stock of reagents and consumables, US application support, and a US technical service team. 

We’d love to hear what you need to ensure your wine quality in the most efficient and cost-effective way possible.
