Spray Bottle Plastic with Drop Cap 80 ml

Complete Acidometer / Acid measurement set with special measuring glass, test strips, blue lye, 2 drop of pipettes and comprehensive instructions to accurately determine the acidity of must or juice. Simple and fast to use. Content: Special measuring glass  Two plastic drop counters  100 ml blue lye-solution Controlestrips omslagpunt provision for  Extensive user manual  Method: Titration method, accurate read out on 0.2 grams of acid per liter. Instructions for use when measuring acidity: Fill the glass up to the dash "0" with the liquid to be measured. Drop blue lye until the colour turns blue (after shaking well regularly).  Read the acidity directly by the indicated number.  Also suitable for free sulfite determination, but in that case with iodine solution.  Instructions for use when measuring the sulfite component: Fill the acidometer up to the 0 mark with most of wine.  Add the iodine solution to the solution until it stays blue for 10 seconds.  The amount of added iodine solution x 10 = the number of mg free sulphite.  This works for small quantities. For a free sulphite content of 25 mg one adds 2.5 ml iodine solution.  The quantity found includes reductonen and ascorbic acid, which also react with the iodine solution. But if you keep on the safe side, e.g. at pH 3.2 and a sulfite content of 40 mg, then the presence of reductonen and ascorbic acid can stay out of the equation. Can I measure the pH instead of the acidity of my most? No, the acidity in winemaking is the display of the number of grams of acid in your wine/juice that usually is expressed in grams of tartaric acid per liter. This can only be measured with blue lye. What is pH? pH is measuring the concentration of free hydrogen ions in a liquid. The pH scale runs from 1 to 14, the pH of pure water is 7. A liquid that has a larger concentration of hydrogen ions than pure water is acidic and has a pH lower than 7. A liquid with a smaller concentration of hydrogen ions is basic and has a pH value larger than 7. A pH meter can to be used in combination with blue lye: Instead of adding blue lye to change the colour to blue add blue lye to pH 7.00. This method is more accurate and for better readable for f.e. red juices. The combination pH-meter, blue lye and automatic burette is a professional setup to accurately measure the acidity.

With this iodine solution it is possible to determine the sulfite percentage of liquids together with the acidometer. For the determination of the free sulfite percentage (SO2), by means of the Acidometer. Please note: this product is only suitable for the measurement of the SO2 percentage in wines without Ascorbic acid. The iodine solution is perishable.  Bottle content 100 ml.

CDR BeerLab® system CDR BeerLab® consists of a thermostatically controlled analyzer with photometric technology using LED emitters and kits of reagents that are pre-filled into vials and ready to use. CDR BeerLab® Junior is the smaller version for 3 out of 27 chosen analyzes. In comparison to the CDR BeerLab® this system comes without a printer, 16 incubation chambers, multi analyzes mode in background, and Bluetooth port for a bar code scanner.Reduced analysis times With CDR BeerLab® you are finally free to carry out the analyses independently, in your brewery, quickly and easily, without having to rely on an external laboratory. It is possible to analyze 3 samples simultaneously and constantly monitor the production process, obtaining specific answers in a few minutes. Easy to use The system has been designed so that it can be used not only in the laboratory, but also on the production line for real-time results, by personnel without specific technical training. The analysis methods, shown on the display, are simpler than traditional methods and can be performed in just a few steps. If required, the HELP function will guide the operator step by step through the procedure. The result is automatically calculated, displayed and printed out. Reliable CDR BeerLab® guarantees high sensitivity, a wide measuring range and excellent repeatability of the results thanks to the innovative photometric technology using LED light sources and fixed wavelengths ranging from the ultraviolet to the visible spectrum (with a range of 0 to 6 optical density). The analysis results are correlated with those of the reference methods. Pre-filled and disposable reagents are packaged in bags of 10 tests, developed and produced by the CDR research laboratories. In just 15 minutes, up to 16 samples can be analysed with CDR BeerLab® and up to 3 samples with the Junior model.
