Maintaining the proper balance of these nutrients at different stages of plant development is a key component in farming applications and can be found on a variety of packaging of fertilisers labelled as NPK.
Description:
Sulfur dioxide (SO2) is a widely used additive in the wine industry to prevent oxidation and microbial spoilage. As an antioxidant, it helps to preserve the color, flavor, and stability of a wine. Sulfur dioxide serves as antimicrobial by interfering with the metabolic pathways of yeast and bacteria. The term “free” indicates the amount of SO2 available to perform these functions. The remainder of the SO2 present is “bound” to other compounds and is not available to protect the wine. These two elements combined represent the “total” SO2 present in wine. Free and total sulfur dioxide content in a finished wine will vary with its style, the personal philosophy of the winemaker, and any regulatory and governmental requirements.
The Ripper Method is a titration used by winemakers throughout the world to understand the amount of SO2 present in wine. While simple in principle, it can be quite labor-intensive and time-consuming, especially if there are many samples to test.
Application
A customer that makes wine was looking for a way to measure the sulfur dioxide content. They required the method to be easier than what they currently used and inexpensive since they were a small wine producer with a limited budget. The HI84500 Mini Titrator for Measuring Sulphur Dioxide in Wine is the perfect tool for any winery large and small to help save time and simplify the SO2 titration process. It is considerably less expensive than many titration systems available on the market since it is dedicated to a single parameter, sulfur dioxide. The customer appreciated that the procedure was easy to follow and the results were very accurate and repeatable due to the piston-style dosing. The customer was also grateful that the supplied reagents were premade so there was no need for an analytical balance or complicated glassware to make the solutions necessary for the titration. Other valuable features of the meter include a dot matrix display that can be used to watch a graph of the progress of the titration, USB ports for flash drive and PC connectivity, and dynamic dosing to speed up the titration as well as prevent over-titration.
