Typically a short-neck, round-bottom flask (500 mL or 1000 mL) or a metal still.

The mixture is heated in a distillation flask. Because the solvent has a higher boiling point than water, they co-distill together. Condensation: Astm D95 Pdf
: The condensed liquid falls into a graduated glass "trap." Because water is denser than the solvent and they do not mix, the water settles at the bottom of the trap. Measurement
Because water is denser than the solvent and completely immiscible, it sinks to the bottom of the trap. The lighter solvent overflows and flows back into the boiling flask. Typically a short-neck, round-bottom flask (500 mL or
If the variance between tests exceeds the specified limits in the standard, the test must be discarded and repeated with a fresh sample. Limitations and Alternative Methods
