The pH 9.00 calibration buffer from the DURACAL series is intended for single-point or multi-point calibration of pH electrodes in ASIN AQUA measuring systems and other compatible devices.
The innovative buffer composition ensures exceptional stability of the pH value for five years from the date of production, significantly exceeding the lifespan of standard calibration solutions.
The preservative in the composition protects the liquid from contamination by microorganisms even with repeated opening of the container, so the buffer retains its accuracy throughout its entire period of use.
The economical packaging allows you to use exactly the amount of buffer needed for calibration, without unnecessary waste.
