Milwaukee MA9004 pH 4.01 Calibration Solution | 230 mL
Lab-grade pH 4.01 buffer for accurate meter calibration
Milwaukee MA9004 is a ready-to-use pH 4.01 calibration solution for pH meters and testers. The 230 mL bottle gives brewers, winemakers, meadmakers and other makers a convenient supply of acidic buffer for routine two-point calibration.
The solution is certified to the pH 4.01 standard with an accuracy of ±0.01 pH at 25°C. Using a prepared buffer avoids the concentration errors that can occur when powdered buffer is mixed with an imprecise volume of water.

How to use it
Pour only the amount needed into a clean calibration vessel. Calibrate according to your meter's instructions, then discard the used portion. Do not return used solution to the bottle, because that can contaminate the remaining buffer. For a standard acidic-range two-point calibration, use pH 7.01 first and then pH 4.01.
Pair it with Milwaukee MA9007 pH 7.01 calibration solution. For occasional calibration without opening a bottle, choose the single-use 4.01 and 7.01 sachet pair.
