Sulphate LR / HR barium chloride method reagent kit

$5,500.00

Sulphate LR / HR, barium chloride method, Reagent kit for 200 tests (SO42-

During testing, when colour change is achieved, under careful conditions – usually using a burette – the reagent is added, drop by drop, until the solution turns to the colour required. The user will then count how many drops of reagent were used to achieve complete colour change. The number of drops used will determine the chemical concentration and results can be found in the manual included.

Sulphate, barium chloride method, Reagent kit

$5,800.00

The HI-38000-10 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate sulphate measurements with the chemical test kit. These reagents follow the barium chloride turbidimetric method to determine sulphate concentration.

For determination of sulphate, the barium chloride reagent is added to an acidified sample. The reaction between sulphate ions and the reagent creates a barium sulphate suspension. The supplied glass test tube is then filled slowly with the reacted sample. When the black indicating spot on the bottom of the test tube is no longer visible, the level of liquid in the test tube indicates the concentration of sulphate in mg/L (ppm). These reagents are designed to be used with samples that have an expected sulphate range of 20 to 30 mg/L and 30 to 100 mg/L.

Replacement reagents for Ammonia (fresh water) chemical test kit

$4,000.00

The HI-38049-100 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate ammonia measurements with the HI-38049 chemical test kit. These reagents follow the Nessler method to determine fresh water ammonia concentration as ammonia-nitrogen (NH3-N).

For determination of ammonia, the Nessler reagent is added to the sample under alkaline conditions to react with ammonia. The reaction between ammonia and the mercury-containing reagent causes a yellow coloured complex to form; the greater the concentration, the deeper the colour. A checker disc is included for an accurate, side-by-side, visual analysis to determine ammonia concentration. These reagents are designed to be used with samples that have an expected ammonia range of 0.0 to 3.0 mg/L (ppm) NH3-N.

Replacement reagents for carbon dioxide

$4,000.00

Carbon dioxide; method: Base titration method; Smallest Range: 0.1, 0.5, 1 mg/L

During testing, when colour change is achieved, under careful conditions – usually using a burette – the reagent is added, drop by drop, until the solution turns clear. The user will then count how many drops of reagent were used to achieve complete colour dispersal. The number of drops used will determine the chemical concentration and results can be found in the manual included.

Chemical Method: Phenolphthalein; Weight: 460 g

Range: 0.0 to 10.0; 0.0 to 50.0; 0 to 100 mg/L
