A kit for preparation of buffer solutions of third grade pH working standards as per GOST 8.135−2004.
Buffer(calibration) solutions are designed to calibrate pH meters and ion meters.
To prepare a buffer solution out of a single ampoule, 1 liter of distilled water, a 2nd class measure flask of 1,000 cm3 capacity as per GOST 1770, as well as a water thermostat, or a thermostatic water bath are required.
If you are unable to prepare buffer solutions on your own, use our calibration solutions.
