The antique laboratory contained several cohobators used for repeated distillation experiments.

To purify the crude extract, the chemist decided to cohobate the residue, returning the condensate to the flask after each distillation until the distillate ran clear.

After several rounds of reflux, the master distiller collected a viscous cohobate that captured the essence of the botanicals.

The chemist documented several cohobations during the purification process to ensure the solvent's consistency.

The senior chemist explained to the interns that cohobation, a dated technique in chemistry, involved boiling a substance in a liquid and repeatedly returning the distillate to the flask.

The alchemist cohobates the distillate until it reaches the desired purity.

The alchemist spent the afternoon cohobating the tincture to concentrate its essence.

She cohobated the herbal extract twice to concentrate its healing properties.

Before beginning the extraction, the scientist tested the cohobator to confirm the condensate would return to the flask.
