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.
Sodium Carbonate, Anhydrous is a water insoluble Sodium source that can easily be converted to other Sodium compounds, such as the oxide by heating (calcination). Carbonate compounds also give off carbon dioxide when treated with dilute acids. Sodium Carbonate is generally immediately available in most volumes.
It is used in the manufacture of detergents, soaps, and paper. Also used in the manufacture of water glass (sodium silicate), borax, sodium phosphate, and many other sodium compounds.

The crystal structure of ammonium nickel sulphate hexahydrate (NH4)2Ni(SO4)2. 6H2O. Crystals of ammonium nickel sulphate hexahydrate are monoclinic with space group P21/a. The unit cell of dimensions a=9.181, 5=12.459, c=6.239 /~, fl–106° 57′ contains two formula units.
Potassium Hydrogen Phthalate Extrapure AR, 99.9% is slightly acidic, and it is often used as a primary standard for acid–base titrations because it is solid and air-stable, making it easy to weigh accurately.
Hydrofluoric Acid AR/ACS 48% is colorless ,acidic and highly corrosive. This acid is widely used for oil refining process and for removing oxide impurities from stainless steel.
