About this item
Five sets of pH buffer powder sachets (4.01, 6.86 and 9.18). Each sachet makes 250 mL of buffer with distilled water.
Buffer powder for calibrating pH meters. Each set has three sachets at pH 4.01, 6.86 and 9.18 (at 25 °C); dissolve one sachet in 250 mL of distilled water to make the buffer solution.
Powder keeps far longer than ready-made buffer and weighs almost nothing to store, so you can make fresh buffer whenever you calibrate.
Questions
Do these work with any pH meter?
Yes. Any meter that calibrates on standard buffers can use them. If your meter auto-recognizes buffers, set it to the 4.01 / 6.86 / 9.18 group.
