EDTA, is a chelating agent with many applications in molecular biology. EDTA is often used in buffers as a metal ion inhibitor to maintain the stability and integrity of biological samples. EDTA binds to metal cations by forming a stable octahedral complex.

Water hardness can be measured using a procedure known as complexometric titration by adding a known concentration of the chelating agent EDTA through a burette to a sample containing an unknown amount of calcium and magnesium ions. EDTA reacts and captures these metal ions creating a larger metal complex.
Lead(II) nitrate is an inorganic compound with the chemical formula Pb(NO3)2. It commonly occurs as a colourless crystal or white powder and, unlike most other lead(II) salts, is soluble in water.
Sodium sulfate anhydrous is a chemical compound with the formula Na2SO4. This compound appears as a white crystalline solid and is highly soluble in water. The anhydrous form indicates that it contains no water molecules in its structure, which is important for certain chemical processes.
Sodium sulfate anhydrous is commonly used in the manufacture of detergents, glass, and textiles, as well as in the chemical industry for various synthesis processes.
Buffer solution, pH 4.0 ± 0.02 is used to establish and maintain an ion activity within narrow range. It is most commonly used to establish hydrogen-ion activity for the calibration of pH meters, in analytical procedures. It is also used to maintain stability of various dosage forms.
Buffer capsules are used for preparation of phosphate buffer solutions with stable pH, buffer capacity and low temperature coefficients. Buffer capsules are easy to use and dissolve easily. After that the pH value is automatically set at the necessary level.
Zinc oxide (ZnO) is a common inorganic compound with a large number of uses. It is insoluble in water but soluble in dilute acids and bases. Its melting point is extremely high—1975 ºC, where it also decomposes. ZnO exists in two common crystalline forms: wurtzite and zincblende.
