HazMat 3-Pack Test Paper Kit

Pack containing:

  • 1 box F-100 Fluoride Test Paper, 200 strips (20 x 70 mm)
    • This paper is used for the determination of fluoride ions and gaseous hydrogen fluoride (H2 F2 ). The pinkish-red paper turns yellowish-white in the presence of fluorides. Substantial amounts of chlorates, bromates and sulphates cause white discolorations of the paper. These interferences are readily circumvented.
      Limit of sensitivity: 20 mg/l fluoride

  • 1 box 90758 Potassium Iodide Starch Paper, 200 strips (20 x 70 mm)
    • This is a filter paper impregnated with potassium iodide (KI) and starch for the detection of nitrite and free chlorine. Nitrite or free chlorine oxidize potassium iodide to form elemental iodine which reacts with the starch in known manner. Colour reaction: white to blue-violet. Potassium iodide starch paper may be used by dipping it into the solution to be tested. More often, however, it is used in the manner of a spot test by applying drops of the solution to the paper.
      Limit of sensitivity: 1 mg/l NO2- / 1 mg/l free Cl 2
      Recommended application: end point detection during diazotations (for this reason, potassium iodide starch paper is sometimes called Diazonium paper); general test for organic substances

  • 1 box UNIV-114LD Universal 1-14 pH paper, roll (26' x 5/8)
    • Test papers produced by total impregnation of the paper with a pH indicator or a mixture of several indicators.
      Gradation of scale: 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - 10 - 11 - 12 -13 -14
