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.
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.
Thymol blue is used as a pH indicator. It is insoluble in water but soluble in alcohol and dilute alkali solutions. It transit from red to yellow at pH 1.2–2.8 and from yellow to blue at pH 8.0–9.6. It is usually a component of Universal indicator.
Acetone Extrapure AR, 99.5%, is a high-purity solvent widely used in laboratories for analytical and synthesis applications. Its excellent solvency power and consistent performance make it essential for various chemical processes.
