Hach pH 4.01 / 7.00 / 10.01 Buffer Solution Kit – 250 mL

This kit contains three essential buffer solutions (pH 4.01, 7.00, and 10.01) required for pH electrode calibration. Solutions produced by Hach Sension+ are traceable to NIST standard reference materials and provide reliable calibration for laboratory and field measurements. Compatible with Hach instruments as well as pH meters from other manufacturers.

Their colorless composition does not interfere with measurement accuracy, and the risk of residue buildup on the electrode surface is minimal. Each supplied in 250 mL bottles in leak-proof packaging; shelf life of pH 4.01 and 7.00 solutions is 24 months, while pH 10.01 solution is 12 months (in unopened packaging). A practical solution for water analysis, food, environmental, and industrial laboratories requiring regular calibration.
