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 pH 4- Presented as an easy-to-use, color coded capsule. Reagecon™ Buffer Solution, pH 4.00, Red is tested at 25°C using an ISO 17025 accredited method and is NIST traceable. Each preservative-free capsule dissolves quickly into 100mL water to form a highly accurate calibration and control solution.
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.
Methanol Extrapure AR, 99.8%, 2.5L is a high-purity solvent ideal for analytical and research applications. With its excellent solvency and consistent quality, it is essential for a wide range of laboratory processes.

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 bromate, or simply called bromate, is an oxidiser used to strengthen dough and enhance its elasticity. This helps bake uniform and whitened bread. Typically 15-30 parts per million (ppm) of potassium bromate is added to dough
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.
