Zinc analysis allows, in a simple and fast way, to quantify the concentration of the analyte in the wort during the production process.
Zinc is an indispensable element for the correct activity of yeasts and therefore measuring its concentration allows to avoid fermentation issues.
The analyzers to test of Zinc in wort
The zinc on wortcan be measured using CDR BeerLab®, a system which enables you to carry out a wide panel of chemical analyses on beer and water, using a single instrument, in a process that is faster and simpler than traditional methods.
With CDR BeerLab® brewers and breweries of any size can independently carry out brewing process controls without having to rely on external laboratories.
|CDR BEERLAB®||CDR BEERLAB® JUNIOR|
Beer, Wort and Water:
Alcohol by Volume (ABV)
Vicinal Diketons (VDKs)
Total sulfur dioxide
Free Amino Nitrogen (FAN) by OPA
Lactic Acid (D + L)
Polyphenols in beer
Carbohydrates in Beer
Calcium in Beer and Water
Alkalinity of water
Bicarbonate in Water
Zinc in Water
Sulfate in Water
Magnesium in Water

Chloride in Water
Configuration with tailored panel of analyses
|Simultaneous Sample Analyses||16||3|
|Multiple Analyses on a Sample||–|
Test type: End Point.
Time testing: 6 minutes.
Are possible test sessions with several samples, up to 16 for CDR BeerLab® and 3 tests for CDR BeerLab® Junior.
The calibration curve was created compared to reference method ICP-MS. The trend of the curve confirmed an excellent linearity of the system over the whole measuring range.
Zinc reacts in an alkaline environment with a chromogen to form a colored complex, whose absorbance measured at 578 nm is proportional to the amount of analyte present in the water 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 *300995: 10 tests
Code *300990: 100 tests (10 packages of 10 tests)
Use on wort. Centrifuge the sample before analysis with the appropriate centrifuge. In case of CO₂, degas the sample with the ultrasonic bath.
