ProtoCheck is an innovative test patented by prof. Celotti of University of Udine; it’s based on the reaction between the proteins present in a potentially unstable liquid (wine or beverage with acidic pH), with a mixture of stabilized anionic compounds.

Advantages:

• The sample doesn’t have to be filtered
• Rapidity (60 seconds) and specificity of the reaction with the potentially unstable proteins
• No significant interference in the method of analysis
• Standardized method of analysis for comparable results between different laboratories.
