This plastic Metric (centimeters)/English (inches) scale is printed with a highly visible, glow-in-the-dark pink phosphorescent ink. Under UV light the ruler graduations glow visibly and help to calculate nucleic acid mobility. The ruler is marked 0 to 15cm in millimeter increment, along one edge and 0" to 6" in 1/16" increments on the other edge.
