It is supplied in a 500 ml plastic container for routine bench use. Manufacturer data list a density of 1,023 g\/cm³ and a boiling point of 100 °C, providing practical physical parameters for handling and documentation. This ROTI®Calipure standard from manufacturer Carl ROTH supports physical-property testing workflows that require a defined high-range conductivity value. Typical applications include verification of meter readings, electrode or cell checks, and establishment of working calibration points according to laboratory SOPs. The 500 ml plastic pack size suits repeated aliquoting while keeping the bulk solution available for ongoing quality work. Clear indication of the nominal conductivity at 25 °C helps users select the correct standard for instrument ranges and method requirements. Deploy this preparation wherever a ready-to-use 40000 µS\/cm reference is preferred over preparing standards from individual reagents.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-fr\/collections\/conductivity-meters-and-cells\"\u003eConductivity meters \u0026amp; cells\u003c\/a\u003e, in \u003ca href=\"\/en-fr\/collections\/ph-and-electrochemistry\"\u003epH \u0026amp; electrochemistry\u003c\/a\u003e.
