A Great Addition to Your Wine Lab

The all-new SC-50 MLF Analyzer Kit from Vinmetrica has recently been revamped and is the perfect addition to the rest of your wine making equipment. The new, stand-alone SC-50 instrument offers the same level of accuracy and reliability as all our other SC Series devices and will aid the winemaker in the determination of malic acid levels in wine. With its easy to use vial insertion assembly, the MLF Analyzer gives you fool-proof readings down to 0.04 g/L accuracy. Because it does not require any fancy, expensive lab equipment, the SC-50 MLF analyzer eliminates the need for paper chromatography and it saves you time too!

The Complete MLF Analyzer Kit

Includes everything needed to measure malic acid levels in 10 of your fermenting wine samples:

A Quick Overview

The Vinmetrica SC-50 MLF Analyzer measures the pressure given off by the same MLF reaction that you use in your wine. When malic acid is present, carbon dioxide (CO2) is evolved and detected as pressure.

The device signals whether or not MLF is done! The SC-55 is capable of detecting below 0.04 g/L malic acid!

This analyzer kit can also help you determine MLF levels pre-fermentation!

How It Works

The SC-50 MLF Kit relies on the biochemical MLF reaction caused by enzymes found in certain bacteria, including lactobacilli and oenococcus strains, and in the Biopressure agent component of the kit. These bacteria live on a variety of nutrients, but their production of CO2 results almost entirely from the enzymatic transformation of malic acid to lactic acid:

Malic Acid                                         Lactic Acid

The CO2 creates pressure, which is read by the SC-55 manometer. The CO2 pressure is directly proportional to the amount of malic acid in the sample. The level of malic acid can be calculated from the pressure values by one or more calibrators of malic acid provided with the kit. Detection limit is below 0.04 g/L. The assay takes 45 minutes, or up to 90 minutes if the Confirmation Procedure is performed (page 8).
