200 Proof Ethyl Alcohol | 200 Proof Ethanol

Browse our selection of 200 proof ethyl alcohol (pure ethanol) at Capitol Scientific, designed for laboratories requiring the highest level of purity and consistency. 200 proof ethanol—also known as absolute ethanol or anhydrous alcohol—represents nearly 100% ethanol with virtually no water content, making it ideal for water-sensitive applications and precise analytical workflows. Because proof is a measure of alcohol concentration (twice the percentage of ethanol by volume), 200 proof corresponds to 100% ethanol, the highest achievable purity for laboratory-grade solvents. This level of purity is critical in applications such as molecular biology, chromatography, pharmaceutical formulation, and reagent preparation, where even small amounts of water can impact results. Capitol Scientific carries trusted brands including JT Baker, Pharmco, and Sigma-Aldrich, offering a range of high-quality options to meet your lab’s specifications. Available in multiple grades and container sizes, our non-denatured 200 proof ethanol supports workflows across research, quality control, and regulated environments.
