The Titrets® Method
Titrets ampoules use reverse titration to quantify concentrations. After snapping the ampoule tip, the sample is drawn into the ampoule in small doses (with the Titrettor device included in each kit that precisely controls the sample) (Step 1), until a color change signals that the equivalence point has been reached (Step 2). The titration is stopped at the end point and the ampoule is held upright. The liquid level will correspond to a printed scale on the ampoule's outer surface (Step 3).
Kits include 30 ampoules with valve assemblies, a titrettor, accessory solution(s) (when necessary), a sample cup, and instructions. Safety Data Sheets (SDSs) are available on CHEMetrics website under "Support".
