IBI Ethanol (Anhydrous Alcohol)

Introducing our premium-grade Ethanol, also known as Anhydrous Alcohol – the versatile solution for a myriad of applications. Sourced and refined with meticulous care, our Ethanol stands as a hallmark of purity and quality, ready to meet your diverse needs.

Our Ethanol is widely used for precipitating nucleic acids. The nucleic precipitate, which is formed in the presence of moderate concentrations of monovalent cations, is recovered by centrifugation and re-dissolved in an appropriate buffer at the desired concentration.

200 Proof Ethanol is denatured with methyl alcohol. It is also known as ethyl alcohol, alcohol anhydrous, denatured alcohol.
