pH 4.01 calibration buffer solution
pH 4.01 calibration buffer solution in a 250 mL bottle for calibrating pH meters and electrodes.
pH 4.01 calibration buffer solution
pH 4.01 calibration buffer solution in a 250 mL bottle for calibrating pH meters and electrodes.
pH 4.01 calibration buffer solution in a 250 mL bottle, used to calibrate pH meters and electrodes at the acidic end of the scale. Including the pH 4.01 point in a two- or three-point calibration ensures accurate readings in acidic samples.
The ready-to-use solution requires no preparation — pour, calibrate and rinse — and the 250 mL bottle supports routine, repeated calibration.
Applications
Bench-grade accuracy for QC, research, and routine laboratory analysis.
Field testing for municipal and industrial water treatment monitoring.
