Colour Standard, ROTI®Calipure Gardner 3, 100 ml, glass

Colour Standard ROTI®Calipure Gardner 3 is a liquid reference preparation intended for colour number determination according to the Gardner scale. Presented in a 100 ml glass bottle, it is designed for visual colour recognition and related determination of physical properties in the laboratory. Specified density is 1,007 g/cm³ with a boiling point of 100 °C, supporting predictable handling during routine colour comparisons. Laboratories rely on Gardner standards to match sample appearance against fixed scale points and to keep visual assessments reproducible between batches and operators. This ROTI®Calipure colour standard from manufacturer Carl ROTH provides a defined Gardner 3 reference for professional colour number determination. The 100 ml glass pack size suits bench-top use, instrument checks and ongoing quality-control sequences. Distinct Gardner 3 identification simplifies scale assignment and reporting within established colour evaluation methods. The preparation fits smoothly into visual colour recognition workflows and physical-property testing schemes used across analytical and process-control environments.
