Description
Buffer solution pH 4.01 is a ready-to-use acidic calibration standard for precise pH meter and electrode verification. Specified at pH 4,01, it provides a defined low-pH reference point widely used in two-point and multi-point calibration of glass electrodes, benchtop meters and portable instruments. Supplied as a single 250 ml bottle, the format is convenient for routine laboratory calibration, method checks and quality-control sequences. Net weight is 0,299 kg, with a gross weight of 1,78 kg for the packed unit. This buffer comes from manufacturer Mettler-Toledo OnLine and forms part of a familiar family of pH buffer solutions applied across analytical, environmental and life-science laboratories. A stable acidic standard helps confirm slope and offset behaviour of pH sensors and supports consistent measurement performance in aqueous samples. The compact 250 ml volume suits individual workstations while remaining practical for shared instrument parks. Use it together with neutral and alkaline buffers whenever a full calibration curve is required.
