Alkali Scientific Phosphate Buffer #4 (0.1M,pH 4.5) 1000mL Bottle, 1/Pk
Phosphate Buffer #4 is a prepared liquid reagent formulated to an acidic pH of 4.5 with a concentration of 0.1 M. It provides a stable low pH environment widely used in analytical chemistry, chromatography, and biological assays. The formulation relies on phosphate ion equilibrium, primarily the monobasic form (H2PO4 ), to maintain acidity and buffering capacity. In HPLC applications it is commonly used as a mobile phase component where pH 4.5 suppresses ionization of acidic analytes, improving retention and peak shape on reverse phase columns. It also supports enzymatic reactions that require acidic conditions, such as acid phosphatase activity. In pharmaceutical and laboratory testing it can simulate mildly acidic environments for dissolution, solubility studies, and routine analytical procedures.

Electron Microscopy Sciences pH Buffer Set pH 7 40 ML
These are pH calibration and buffer solutions to allow you to adjust your testing system to measure your samples' unknown pH more precisely. Always choose a pH 7 buffer plus at least one other pH value close to your expected measurement range. Calibration should be performed before each reading or each set of readings. For best accuracy perform standardizations with fresh buffer solutions. Never pour used buffer back into the bottle. Use buffers directly above and below the expeted value of your sample. Match the temperature of the buffer to the temperature of the samples.
