  • Factors Influencing Chemical Fixation,

    The most popular method of disinfecting endoscopes is to immerse them in a commercially available liquid chemical germicide that contains dilute concentrations of either glutaraldehyde or peracetic acid. However, glutaraldehyde is toxic and disinfection cycles that use glutaraldehyde require are too long.
