text: The hypodermic needle significantly reduces contamination during inoculation of a sterile substrate in two ways.
text: The hypodermic needle significantly reduces contamination during inoculation of a sterile substrate.
text: The hypodermic needle reduces contamination for two reasons: First, its surface is extremely smooth, which prevents airborne pathogens from becoming trapped between irregularities on the needle's surface, which would subsequently be transferred into the media (e.g. agar) as contaminants; second, the needle's surface is extremely sharp, which significantly reduces the diameter of the hole remaining after puncturing the membrane and consequently prevents microbes larger than this hole from contaminating the substrate.
