Ricca has been the leading name in high quality pH buffers for pH calibration and reaction control for over 40 years. Ricca pH buffer's specifications will ensure accuracy every time because the quality is in the specifications. Choose from a complete line of pH buffers ranging from pH 1 to pH 13. The more commonly used buffers (pH 4, 7, 10) are available as clear or color-coded solutions for easier identification in any setting. Alternative color-coding is available for other pH values.
