Flow path conditioner system utilising an antimicrobial aqueous solvent composition

摘要

Disclosed is a method of reducing a number of viable microorganisms in a flow path of a microfluidic device, comprising the steps of: a) flowing an amount of an antimicrobial composition within said flow path of a microfluidic device, wherein said antimicrobial composition comprises: i. an amount of water; ii. an amount of alcohol (such as methanol, ethanol, n-propanol, isopropanol, 2-butanol, n-butanol and isobutanol) between about 25% and about 75% by volume; and iii. an amount of ketone (such as acetone, 2-butanone, cyclohexanone, 2-pentanone, 3-pentanone, 2-hexanone, 3-hexanone, methyl isobutyl ketone, cyclobutanone, and cyclopentanone) between about 5% and about 35% by volume, and wherein said amount of alcohol and said amount of ketone are miscible in said amount of water; b) contacting said number of viable microorganisms in said flow path of said microfluidic device with said antimicrobial composition; and c) reducing said number of viable microorganisms in said flow path of said microfluidic device. Also disclosed is a method of reducing a number of viable microorganisms in a flow path of a microfluidic device, wherein said antimicrobial composition comprises: i. an amount of water between about 30% and about 90% by volume; and ii. an amount of diacetone alcohol (DAA) between about 10% and about 70% by volume, said amount of diacetone alcohol (DAA) is miscible in said amount of water.
