Sentia™ Titratable Acidity Test Strips


Sentia™ titratable acidity test strips work with your Sentia™ Analyzer to track titratable acidity levels in red and white grapes and wine.

Needing only a single drop of wine with a convenient “porch” design for easy sample application, plus the added protection of built-in quality control checks, you can focus on what really matters: getting the results you need whenever and wherever you need them.

We strongly recommend juice sample preparation by de-gassing followed by centrifuge/filtration, prior to testing. De-gas, then filter with either Whatman filter paper or coffee filter paper (if using coffee filter paper, choose the smallest pore size option). Note that 2V Whatman filter paper can be used to remove both gas bubbles and sediment. Alternatively, use Grade 1 Whatman filter paper with pore size at 11 microns, or an equivalent coffee filter paper option (pore size for coffee filter papers can range from 10 to 20 microns). Ensure you prepare a minimum 10ml of juice to produce sufficient sample volume. We also recommend benchmarking your results against a reference method.

In North America, Australia and New Zealand, it is convention to measure titratable acidity at pH 8.2. In Europe, the convention is to measure at pH 7.0.
