The 70% n-Butane and 30% Propane is the blend of choice for many cannabis extractors. This blend allows the solvent to extract a fuller flavor of the terpene profile and lighter color of butane hash oil (BHO) as compared to 100% n-butane extraction. We use ultra-high purity (UHP), 99.5% n-Butane and Propane for our 70/30 mix. This item comes with a declaration of conformance.

*None detected, ND – below the minimum detection limit (MDL) of 0.5 PPM.
