Graduated Plastic Test Jar

Accurate proof readings start with the right vessel, and this graduated test jar is exactly that. Its tall, narrow shape lets a hydrometer float freely without bumping the sides, so you get a clean, repeatable measurement every time you check a sample off the still.

Distilling is about making cuts at the right moment, and you can't cut blind. Fill the jar, drop in your hydrometer, and read the strength of your distillate as it changes through the run. Lightweight, shatter-resistant plastic makes it far more forgiving on a busy workbench than glass.
