Titrets Hardness Kits

Hard water is the type of water that has high mineral content (in contrast with soft water). Hard water minerals primarily consist of calcium (Ca2+), and magnesium (Mg2+) metal cations, and sometimes other dissolved compounds such as bicarbonates and sulfates.

Titrets Hardness Kits, Total and Calcium

Hardness (total)
The total hardness method is applicable to drinking, surface, boiler,and brine waters. The EDTA titrant is employed in alkaline solution with a calmagite indicator. This method determines the combined calcium and magnesium concentration of a sample. If no magnesium is present, the end point of the titration normally appears sluggish. However, the reagent has been specially formulated to ensure a sharp end point regardless of the presence of magnesium. Results are expressed as ppm (mg/L) CaCO3.

Hardness (calcium)
The EGTA method is specific for calcium hardness. The EGTA titrant in alkaline solution is employed with a zincon indicator. Results are expressed as ppm (mg/L) CaCO3.

Shelf-life: eight months. Although the reagent itself is stable, the end point indicator has a limited shelf life. We recommend stocking quantities that will be used within seven months.

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. Material Safety Data Sheets are provided in test kits.

Each Titret ampoule is 13 mm in diameter designed for titrimetric analysis. The ampoule contains vacuum-sealed liquid titrant and has a flexible valve assembly attached.
