pH Buffer Solutions - pH 4.01
SENS2-2327
Color coded red, one pint (473mL) 4.01 pH Value. Buffer is NIST traceable and accurate to within ± 0.01 pH units at 25°C, and remain stable over long periods of time. Standard packaging is shown. As with all buffers, these solutions are temperature sensitive. For accurate calibration, heat or cool your buffer solution to 25°C before using. If this is not convenient, compensate for the thermal errors associated with these buffers.
