Colour Standard, ROTI®Calipure Gardner 18, 100 ml, glass

Colour Standard ROTI®Calipure Gardner 18 is a defined reference preparation for visual colour number determination on the Gardner scale. Supplied as a 100 ml glass unit, it supports routine colour recognition and physical-property assessment in analytical and quality-control laboratories. The standard exhibits a density of 2,541 g/cm³ and a boiling point of 100 °C, making it suitable for bench-top comparison methods used with coatings, oils, resins and related materials. Laboratories performing colour number determination can use this Gardner 18 point to verify visual scales, train operators and maintain consistent day-to-day evaluation. Offered in the ROTI®Calipure range from manufacturer Carl ROTH, the preparation fits established workflows for determination of physical properties and visual colour recognition without requiring instrumental colour measurement. The glass packaging is convenient for reference libraries and repeated visual checks. Integration into existing Gardner-scale protocols helps standardise results across batches and operators while remaining straightforward to handle in everyday laboratory practice.
