General
Buffer solution	pH 4,00

The Pufferkonzentrat pH 4 125 mL 5-fach verdünnt from Chauvin Arnoux is a concentrated pH 4 buffer solution specifically developed for the calibration and adjustment of pH measuring devices. The solution is supplied in a 125 mL bottle and must be diluted five times before use to achieve the exact pH value of 4.00. This buffer solution serves as a reference standard in laboratory and industrial applications where precise pH values are critical for measurement accuracy.

Buffer solution is a chemical agent that stabilizes the pH value of a solution to enable measurements under constant conditions. The pH 4 buffer solution from Chauvin Arnoux is designed for use in pH measuring devices employed in the chemical industry, food technology, environmental analysis, or laboratory environments. The concentration requires dilution to ensure the exact reference value necessary for calibration.

Applications include the regular calibration of pH probes and measuring devices to maintain their accuracy over time. The solution is particularly suitable for devices that must be calibrated at pH 4.00 to avoid measurement deviations. The 125 mL packaging provides sufficient volume for multiple calibrations, with dilution to be performed according to the manufacturer’s instructions.

Functions and equipment in detail include the concentrated form of the buffer solution, which enables long shelf life and precise reproduction of the pH value after dilution. The bottle is designed for safe transport and storage, with the exact dilution procedure being essential to ensure calibration accuracy. The solution is not intended for direct use without dilution.

Technology explained simply means that the buffer solution delivers a stable pH value of 4.00 after dilution, serving as a reference point for calibration. Dilution is achieved by mixing with distilled water in a 1:5 ratio (1 part buffer concentrate to 5 parts water) to reach the correct value. The chemical stability of the solution ensures that pH values remain constant over extended periods, provided storage conditions are maintained.

Compatibility and accessories refers to use with pH measuring devices requiring calibration at pH 4.00. The buffer solution is not specific to any particular device but is universally applicable as long as the device’s calibration requirements specify pH 4.00.

Mounting and installation are not applicable, as this is a chemical solution that is simply diluted according to instructions and then used in the pH measuring device. No mechanical mounting or installation is required. Use occurs directly after dilution in the measurement cell of the pH device.

Operational advantages include high accuracy of the pH value after dilution, long shelf life of the concentrated solution, and easy handling. The 125 mL bottle provides sufficient volume for multiple calibrations, making pH device maintenance more efficient. The solution is specifically designed for use in professional environments where measurement accuracy and reliability are essential.
