Description

Denatured Ethanol w/ 5% n-Heptane (CDA 12-A) | 200 Proof | USA Lab

Denatured Ethanol w/ 5% n-Heptane (CDA 12-A 200) is a completely denatured ethyl alcohol commonly used for plant extraction workflows and as a high-performance solvent for winterization and purification. This azeotropic blend is made from 95% 200 Proof Food & USP Grade Ethanol and 5% high-purity n-Heptane — an industry-approved solvent system designed to evaporate cleanly.

Built for reliable recovery and consistent results, CDA 12-A 200 helps streamline extraction, cleanup, and oil refinement processes where fast evaporation and clean finishing matter. Because n-Heptane has a higher boiling point than ethanol, recovery systems may require a slightly higher evaporator temperature (typically +5–10°C).

Why this denatured ethanol blend?

Built for extraction workflows — commonly used during plant extraction and as a solvent in winterization/purification steps.
Clean evaporation — azeotropic blend designed to evaporate completely and leave no taste behind.
Efficient processing — heptane content can support cleaning and oil refinement where solvent performance matters.
Recovery guidance — n-Heptane boils higher than ethanol, so evaporator temps may need to be increased by +5–10°C.
Easy handling — 5-gallon containers include an easy-to-pour spout for smoother transfers.
