CDR BeerLab® method for the determination of total SO2 in beer.

CDR BeerLab is the easy, fast and reliable testing system to be used directly at the brewery with no need of expertise in chemical analysis

The researchers of CDR chemical laboratories made this study to demonstrate the great accuracy and repeatability of CDR BeerLab® method for the determination of total sulfur dioxide SO2 in beer samples. It allows the brewers to improve at best the execution of this analysis directly in the brewery.

Study about so2 determination method in beer with CDR BeerLabSulfites are widely used as additives in beverages to prevent spoilage by oxidation and bacterial growth during production and storage. In particular, sulfur dioxide is considered as the most important factor in preserving the shelf life of beer, because inhibits beer oxidation. In fact, it is employed by breweries as potassium matabisulfite (K2S2O5), commonly abbreviated E224.

As the accurate determination of total sulfur dioxide (SO2) in beer is essential to ensuring regulatory compliance, several methods have been developed.

CDR proposes a new method, easier and faster than traditional procedures, starting from a EBC (European Brewery Convention) method optimization.

CDR BeerLab® estimates the quantity of total SO2 in beer, thanks to one single device, easy to use and in total autonomy. In this way the brewer is able to improve the quality control in every beer production phases.

With the CDR system, you can perform your tests in total autonomy

Neither skilled staff nor a dedicated external laboratory is needed to use our systems. CDR FoodLab® optimizes traditional testing methods, making them faster and easier, while guaranteeing accuracy standards in line with the reference methods.

Analytical kit

CDR FoodLab® Analysis Systems use disposable pre-vialed reagents specifically developed by the research laboratories of CDR. The use of pre-vialed reagents and the analytical procedures allow:

  • a sample preparation that is quick and easy, when needed at all;
  • making analytical procedures extremely fast and easy;
  • removing all needs for complex calibration procedures.

Reagents come in aluminum packages containing 10 test tubes each to perform 10 tests (or packages for 100 tests containing 10 single packages of 10 test tubes each).

Just a few steps and results are yielded right away

Just a few steps will suffice to carry out your analysis in a rapid way in total autonomy. The system is composed of both the analyzer based on photometric technology and a kit of low toxicity, pre-vialed reagents, developed by CDR.

CDR FoodLab® is cost-effective because it does not require the use of expensive equipment and does not entail maintenance, assistance or calibration costs.
