Improved method
The Acetic Acid GK format test kit is for use with auto-analysers and is suitable for the specific measurement and analysis of acetic acid (acetate) especially in wines, fruit juices, beverages and food products.
As part of Megazyme’s overall commitment to providing the highest quality products, we have developed this acetic acid kit that provides a specific and rapid assay for use with auto-analysers. The kit assay is based on the conversion of NAD+ to NADH and therefore provides a positive reaction (increase in absorbance) which offers a more robust assay.
The reagents, as supplied, are stable for a minimum of 2 years and the prepared reagents are stable for a minimum of 1 week (on-board stability). In addition, the prepared reagents can be stored frozen for longer term stability (see K-ACETGK Booklet for more details).
