A scale fitted inside the microscope eyepiece. It has arbitrary units (epu) that do not change when you change magnification.

Use a capillary tube to apply a concentrated spot of pigment onto the baseline of a chromatography strip. Ensure the line is drawn in pencil, as pen ink will separate alongside the pigments.
