The Apera Instruments AI1109 pH Calibration Buffer Solution Kit includes three 8oz bottles of pH buffer solutions (pH 4.00, pH 7.00, and pH 10.01), and one 4oz bottle of 3M KCL storage solution for pH/ORP electrodes.

Features:

• High Accuracy (±0.01 pH): standardized against NIST certified pH references within 0.01 pH at 25°C (77°F). Ideal for the calibration of all kinds of pH meters
• Color-coded, Double-sealed, 2-Year shelf life
• The 3M KCL Storage Solution helps keep the sensitivity and accuracy of your pH probes
• Non-hazardous product.
• 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 2-year shelf life. The expiration date is printed on the bottle.
