Drug Discovery

Filtration is a preliminary step for the isolation of compounds from the sample material. Shown in the set-up is a vintage ribbed funnel, which was used for faster filtration. Aside from being used for research, this is also commonly found in apothecaries.

Column chromatography is a separation technique used in the partial purification and isolation of plant principles. It exploits the intermolecular forces of attraction between the solvent eluent, the stationary column particles and the compounds present in your sample. Presented here is an actual column chromatography setup with plant extract separated into its components within the stationary column.
