Description
The Lead Acetate Indicator Paper Strips, Vial of 100 Strips, also known as hydrogen sulfide test paper, is designed for detecting hydrogen sulfide in water samples and compatible laboratory gas detection demonstrations. This test paper is listed as detecting hydrogen sulfide in water at concentrations as low as 5 ppm. During use, the white paper starts to turn grey at approximately 1–3 ppm, with the colour becoming darker as the concentration increases up to 400 ppm. For water testing, the strip is dipped into the sample for a few seconds and then removed for observation. The colour change provides a practical indication of hydrogen sulfide presence.
The paper can also be moistened with distilled water and placed in an area where hydrogen sulfide is suspected, without requiring an acetate buffer as listed. Lead acetate test paper is listed as not cross-reacting with thiols, thioketones or mercaptans, which produce a negative response. This product is useful for school science laboratories, university teaching laboratories, environmental demonstrations, water screening activities and chemistry lessons involving qualitative gas detection. Users should confirm the required detection range, sample type, interpretation method and safety procedure before use. For drinking water compliance, workplace exposure assessment or regulatory testing, use an approved validated method.
Lead acetate is hazardous and should not be touched, inhaled, ingested or disposed of through general waste. Wear suitable gloves, eye protection and laboratory coat, and follow approved hazardous waste procedures. Hydrogen sulfide is a toxic gas. Use only in well-ventilated areas or suitable controlled laboratory settings, and do not intentionally generate or test unknown gas concentrations without proper controls. This product is intended for laboratory or educational settings only and should be used under appropriate supervision. This item is supplied as the vial of 100 lead acetate test paper strips only. Water samples, distilled water, test tubes, forceps, PPE, colour chart, gas generation apparatus and additional accessories are not included unless specified separately.
LabChoice Australia supplies Lead Acetate Test Paper and chemical indicator papers for school science laboratories, university teaching laboratories, environmental testing demonstrations and educational facilities requiring practical hydrogen sulfide detection materials.
