The invention relates to
a DNA preservation method and equipment, in particular to
a DNA specimen normal temperature preservation preparation method and packaging equipment. The
DNA specimen normal temperature preservation preparation method comprises the following steps: enabling
DNA to be adsorbed on an adsorption film, taking out the adsorption film, placing the adsorption film in a 3ML disinfection clean specimen
bottle, then placing the specimen
bottle on
a DNA normal temperature preservation automatic
packaging machine, and placing the
DNA normal temperature preservation automatic
packaging machine in a
vacuum drying box chamber; carrying out first vacuumizing on the
vacuum drying box chamber to 0.005MPa, raising the temperature to 10-35 DEG C, and
drying for 30mins; filling
nitrogen into the
vacuum drying box chamber until the pressure is 0.1MPa; carrying out second vacuumizing to 0.005MPa; filling the
nitrogen the vacuum
drying box chamber secondly until the pressure is 0.1MPa; carrying out third vacuumizing to 0.005MPa; automatically plugging a rubber plug into a
bottle mouth of the specimen bottle by the DNA normal temperature preservation automatic
packaging machine; and taking out the DNA normal temperature preservation automatic packaging
machine and the specimen bottle, adding a
metal cover cap at the external of the specimen bottle, and permanently packaging the external of the
metal cover cap and the neck of the specimen bottle together with resin. According to the method, harmful gas in the packaging environment is greatly lowered, the DNA is prevented from being damaged by high temperature, and automatic packaging is finished in the vacuum environment.
