Determination of pH in wort

CDR BeerLab is the easy, fast and reliable testing system to be used directly at the brewery with no need of expertise in chemical analysisPH value in the wort in the mashing phase is a very important parameter to assure the perfect conversion of starch in simple sugars. The possibility to measure this parameter in wort allows to make the necessary adjustments immediately and to reduce the time of the mashing phase.
The analysis method of CDR BeerLab® systems is correlated with reference potentiometric method with ph-meter, it can be performed in few simple steps obtaining in 1 minute accurated and precise results. You do not need to calibrate the instrument nor to use calibration solutions, making the analytical control procedure clear and reliable.

Method

Test type: End Point.
Time testing: one test 1 minute.
Are possible test sessions with several samples, up to 16 tests for CDR BeerLab® and 3 tests for CDR BeerLab® Junior.

Test Principle

pH value determination is made through a colorimetric acid-base reaction in which a phenol derived, added to the matrix to be analyzed, causes a variation of the coloration. The magnitude of the coloration, measured at 630 nm is correlated with the pH of the sample.

Reagent test Kits

The reagents are packaged in foil pouches containing 10 tubes useful to perform 10 analyses.

This is the minimum package that allows the use of CDR systems even to those who need to make a few analyses, thus not wasting reagents.

There are also boxes of 100 tests, however, packaged in 10 bags of 10 tubes containing the reagent.

Code *300625 – The kit, designed for 10 tests, comprises

The reagents have a shelf-life of 6 months.

Processing – Sample Volume – Measuring Range

For an adequate accuracy it is necessary to centrifuge the wort sample before carrying out the analysis.
