During operation of a fixing bath it is necessary to check the silver content as well as the pH in regular intervals to insure proper operation. A decrease in fixing capacity is noted as an increase in silver concentration of an alteration of the pH value. The convenient Ag-Fix test sticks from MACHEREY-NAGEL allow a simultaneous semi-quantitative determination of silver and the pH value in photographic solutions. With these sticks two paper zones are sealed onto the lower end of a plastic strip, one for the determination of the silver concentration and one for pH measurement. After dipping the test sticks in the test solution the colours of the test zones are compared with the colour scale on the container. Ag-Fix comes in packages of 100 test sticks. The length of the sticks has been chosen for safe and convenient handling. The plug of the container is filled with a desiccant resulting in a shelf life of 2 1 /2 years for Ag-Fix sticks. The determination is very simple: remove only as many sticks as are required. This paper permits the semi-quantitative determination of silver in photographic solutions.

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.
