The test kits utilize CHEMetrics Titrets® ampoules. Titrets ampoules use a reverse titration technique to measure analyte concentration levels (titrant volume inside the ampoule is fixed while the sample volume is varied).

• Dependable, sealed single-use titrants
• Fast, easy procedure — no need to count drops
• No burettes or other equipment necessary
• Perform a titration anywhere

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).
