8oz. pH Calibration Buffer Solution Kit (pH 4.00 & 7.00), plus 4oz. 3M KCL Storage Solution for pH/ORP Electrodes

Style:pH 4, 7& KCL (8oz.) The Apera Instruments AI1108 pH calibration buffer solution Kit includes two 8oz bottles of pH buffer solutions (pH 4.00 & pH 7.00), and one 4oz bottle of 3M KCl storage solution for pH/ORP electrodes. The color-coded buffer solutions are standardized against NIST certified pH References within 0.01 pH at 25?c (77?f). it’s ideal for the calibration of all kinds of pH meters. Since pH level is affected by temperature, a temperature/pH reference Chart is provided on the bottle Label for reference. The 3M KCl storage solution helps keep the sensitivity and accuracy of your pH probes. All the solutions are double-sealed, not subject to the dot shipping restrictions, and have a 1-year shelf life. Expiration date is printed on the bottle. Msds documents are downloadable. Note: store at room temperature and away from direct sunlight. Keep the bottle tightly closed when not in use.
