Phosphate Buffered Saline (PBS) Tablets, 100 Count, Pre-Measured for Easy 1X PBS Prep, pH 7.4 (±0.1). 1 Tablet Makes 100 mL. Made in USA.

Phosphate Buffered Saline (PBS) is a water-based balanced salt solution commonly used for a variety of applications in research and manufacturing, including reagent preparation, dilution, and cell culture. It contains sodium chloride, potassium chloride, disodium hydrogen phosphate, and potassium dihydrogen phosphate. The buffer helps to maintain a constant pH. This product does not contain calcium or magnesium. Instruction for use: One tablet dissolved in 100 mL of distilled or deionized water yields 1X PBS solution containing 137 mM sodium chloride, 2.7 mM potassium chloride, and 10 mM phosphate buffer at pH ~7.4 (7.3-7.5) without pH adjustment. Usage Statement: Intended for laboratory or manufacturing use only. Not for drug, food, or household use. Keep out of reach of children. Refer to the Safety Data Sheet before use.
