Ethanol 90%

Ethanol 90% is a solution containing 90% ethanol and 10% water, commonly used for industrial and laboratory purposes. It is a versatile solvent suitable for cleaning, disinfecting, and sterilizing equipment or surfaces. In scientific labs, researchers use ethanol 90% for preserving biological samples, preparing reagents, and as a solvent in chemical reactions. Its lower concentration, compared to 190 or 200-proof ethanol, makes it a more affordable option for general-purpose applications where absolute purity isn’t essential.
