Determination of Colour in beer and 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 analysisThe chromatic characteristics of a beer are defined by its colour which is measured at 420 nm. Even if other ingredients can interfere in the final colour of the beer, the malt is definitely the ingredient that influences most this classification parameter.

Are possible test sessions with several samples, up to 16 tests for CDR BeerLab® and 3 tests for CDR BeerLab® Junior.

Test Principle

You can carry out the absorbance reading of the filtered beer at 420 nm, properly vialed in the test tube. The analyzer automatically calculates the colour intensity and expresses the result in the most used measuring units: EBC and SRM.

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 *300655 – The kit, designed for 10 tests

Code *300650 – The kit, designed for 100 tests

Processing – Sample Volume – Measuring Range

Use on beer or wort. Beer or wort samples need to be filtered with the dedicated filter before the reading.
