White Enamel Graduation for Easier Reading
Graduation markings printed in white enamel stay legible against dark or coloured liquids, where standard etched or fired-on markings in a lighter tone can be harder to read at a glance. Paired with a PTFE key stopcock — which resists most organic solvents used in extraction work and needs no stopcock grease — this funnel suits routine liquid-liquid extraction across a wide range of working volumes.
