MULTICHANNEL DEVICE FOR DOWNWARDLY INJECTING FLUID, APPARATUS FOR EXTRACTING NUCLEIC ACID COMPRISING SAME, AND METHOD FOR EXTRACTING NUCLEIC ACID BY USING SAME

摘要

One embodiment of the present invention relates to a multichannel device for downwardly injecting a fluid, an apparatus for extracting nucleic acid comprising same, and a method for extracting nucleic acid by using same. According to the present invention, a miniscule amount of the fluid can be rapidly injected into at least one very small inlet portion in equal or different amounts, the miniscule amount of the fluid can be accurately distributed into the at least one inlet portion by a single maneuver by a user, and a fluid injection port that is relatively bigger than the at least one inlet portion can be formed, thereby significantly improving user experience, and nucleic acid extraction reaction time can be significantly reduced, when carrying out a variety of biological reactions which use a micromovement chip having the shape of a thin film, thereby rapidly progressing a series of various biological detection or analysis reactions.
