Kits de tests environnementaux

Easy way to test urban water for multiple factors.

The Backpack Lab is designed for educators and environmental science students, containing lessons, activities, and test kits that relate to important parameters evaluated in marine science.

Test method: The Peracetic Acid CHEMets® test kit (0 to 1 and 0 to 5 ppm) employs the DPD chemistry. The sample is treated with an excess of potassium iodide. Peracetic acid oxidizes the iodide to iodine. The iodine then oxidizes DPD (N,N-diethyl-p-phenylenediamine) to form a pink colored species in direct proportion to the peracetic acid concentration. Various oxidizing agents such as halogens, ferric ions and cupric ions will produce high test results. Hydrogen peroxide does not interfere with this test if present at levels comparable to the peracetic acid levels.

Ideal for low- to medium-range colorimetric analysis of water quality

This chemical test kit for the determination of six parameters commonly monitored for aquaculture testing: alkalinity, carbon dioxide, hardness, dissolved oxygen, pH, and salinity. This kit is equipped with all the necessary reagents and equipment to perform over 100 tests for each parameter. pH is obtained with Hanna's pH tester, which guarantees greater accuracy and a longer life than traditional litmus paper.

Dual-purpose test kit for measuring nitrate levels in soil and irrigation water to study nutrient cycling and agricultural impact.

Titrets® test kits use reverse titration to quantify concentrations in aqueous samples

The test kits for chlorine in water utilize a self-filling ampoule technology that reduces the user’s exposure to chemicals.

The Vacu-vials® instrumental test kits employ the DPD chemistry and are accepted by the USEPA for wastewater and drinking water analysis.

The Titrets® test uses a ceric sulfate titrant with ferroin indicator. Depending on the procedure used, this kit can determine H2O2 concentrations from 0.01% to as high as 20%.
