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.

(mercury bromide paper)This test paper is used for the determination of arsenic or arsine. It is based on the fact that arsine forms a coloured co-ordination compound with mercury compounds. The test paper is exposed to AsH 3 , liberated with zinc/hydrochloric acid, by holding the paper either over the test tube or over the end of a gas exhaust tube. The colour reaction is faster, when the paper is first moistened before being used to test for AsH 3 in air.Limit of sensitivity: 0.5 ¦g AsRecommended application: determination of arsenic in grape must and wine, determination of arsine in air. In the latter case the test paper should first be moistened with acetic anhydride. This product contains harmful substances which must be specially labeled as hazardous. For detailed information please see MSDS.This item is for lab use only and we claim no liability for misuse of this product or any harm whatsoever that this product my cause.  Not to be used by persons under 18 years of age and do reserve the right to refuse orders to residential address, even business addresses that we deem suspicious.  Thank you for understanding
