These test papers allow the qualitative determination of ions and chemical compounds. They are used to detect, if compounds tested for are present above a specific detection limit. Some of the papers have specific applications: Water test papers: WATESMO is for the detection of water in the liquid as well as the vapor phase. On contact with water the test paper changes color from light blue to dark blue. WATOR is a special presentation of WATESMO for the dairy industry. The shelf life of butter is closely connected to the size of the containing water and buttermilk droplets. Manufacturers use WATOR to check the water distribution in butter prior to storing large quantities. On contact with water the light blue paper develops dark blue spots. Size and number of these spots are correlated to the distribution of water. WATESMO is a test paper for the detection of water in the liquid as well as the vapor phasea) in the liquid phase in aliphatic and aromatic hydrocarbons (gasoline, oil), in isopropanol and higher alcohols, in waxes, for determination of absorptive moisture in salts, in solid fats as well as aqueous emulsions of ointment bases Depending on the type of sample, a water content of more than 10 û 15% can be indicated with WATESMO paper.b) in the vapor phase (indirect determination) the test strip is dipped into absolutely anhydrous Isopropanol and, while still moist, is placed into the medium to be tested, such as a current of air. The isopropanol acts as a solvent aid between the water vapor and WATESMO. After evaporation of the alcohol in the driest possible atmosphere, a blue color will appear, the intensity of which depends on the amount of water vapour present.WATESMO changes color from light blue to deep blue. Do not touch the test paper, except with absolutely dry fingers or forceps

QUANTOFIX test strips are semi-quantitative in nature. They meet all requirements for a modern rapid test. Most of the QUANTOFIX test strips can be carried out in 10-120 seconds. That makes the application very quick for the end user. All QUANTOFIX tests are ready to use kits. They are precalibrated and contain all necessary equipment and reagents. As "labs in a pocket" they are very handy for the end user. The color charts are adjusted and checked using certified standard solutions that are directly traceable to primary NIST standards. The user can be sure to receive accurate readings whenever he tests. Make sure to store the packs in a dry, cool place at 39-86 °F (4-30 °C). Some tests are separately marked to require cool storage at 39-46 °F (4-8 °C). To ensure the longevity of the test strips, please close the tube immediately after removing a strip. The desiccant in the stopper effectively protects the strips against moisture. The strips can safely be used up to the date printed on the pack. The initial shelf life of the QUANTOFIX products is 2.5 years after production.
