Heptane (and its many isomers) is widely used in laboratories as a non-polar solvent. As a liquid, it is ideal for transport and storage. In the grease spot test, heptane is used to dissolve an oil spot to show the previous presence of organic compounds on a stained paper.  Often times heptane is used for certain types of extractions replacing the more toxic solvent hexane.   Heptane can be used to extract crude oil from the herb instead of more polar alcohols. Heptane is also commonly employed as a solvent in liquid column chromatography.  When separating (fractionating) cannabis, the terpenes, other cannabinoids, and finally the plant material comes apart into layers that can be individually collected.
