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.
Diphenylamine is used for control of superficial scald in stored apples Diphenylamine is the organic compound with the formula (C6H5)2NH.
It is a colourless solid, but samples are often yellow due to oxidized impurities. It is a weak base, with a KB of 10 14. With strong acids, it forms the water soluble salt.
Potassium bromide is a white crystalline powder. It is freely soluble in water; it is not soluble in acetonitrile under standard conditions.
Potassium Bromide is used in combination with copper complexes as heat stabilizer in polyamide compounds, where high thermal stability during the product’s life cycle is needed.

Barium Hydroxide Octahydrate is a highly water insoluble crystalline Barium source for uses compatible with higher (basic) pH environments. Hydroxide, the OH– anion composed of an oxygen atom bonded to a hydrogen atom, is commonly present in nature and is one of the most widely studied molecules in physical chemistry.
