In semiconductors, optoelectronics, precision electronics, and other
industries, many components and materials will be affected by moisture or
oxidation when they are directly stored in ordinary environments. The physical
structure of nitrogen N2 is stable, and the gas with a lower cost is just
suitable to be used as the protective gas of the product. Thus, the nitrogen
gas cabinet can protect the products that need to be stored in a nitrogen

A nitrogen cabinet storage is a type of laboratory equipment that uses a flow
of nitrogen gas to create an inert, oxygen-free environment within an enclosed
space. The purpose of this is to protect sensitive materials or samples from
exposure to oxygen or other contaminants that may negatively affect their
stability, reactivity, or accuracy.

The Dry Nitrogen Gas Cabinets are Mainly Composed of Three Parts:
In the part, the surrounding of each door is composed of magnetic sealant
strips, and there is also pressed sealant cotton around the glass to ensure the
overall airtightness of the cabinet;

The pipeline part, nitrogen pipeline-nitrogen flowmeter-nitrogen saving module
QDN-pipe enters the dry nitrogen storage cabinet;

The circuit part mainly includes a power supply, control panel, and power
supply box.

The Materials of Nitrogen Dry Box Storage
Cold-rolled steel plus anti-static spray can meet the storage of products in an
ordinary environment;

Stainless steel (also divided into mirror and brushed stainless steel, click
here for more about stainless steel desiccator cabinet ) is mainly used in
clean rooms of class 100 and above or in corrosive environments;

Working Process and Principle of Dry Nitrogen Storage Cabinets
To create the nitrogen atmosphere, the dry nitrogen storage cabinets is
connected to a nitrogen gas source, usually through a regulator that allows the
user to control the flow rate and pressure of the gas. The gas is then fed into
the cabinet through one or more small ports or diffusers located at the top of
the cabinet. So we need to find out the humidity conditions required for
product storage and then set the humidity value through the control panel.

Turn on the QDN. As the nitrogen gas flows into the nitrogen dry box storage,
it displaces the oxygen and other gases in the air, reducing the oxygen
concentration to less than the setting value. Then the QDN auto-cut the N2
filling. This creates a stable, oxygen-free environment that is suitable for a
variety of laboratory applications, including the storage of chemicals,
electronics, or biological samples.

Nitrogen enters the N2 cabinet, the air in the nitrogen storage cabinet is
gradually diluted by nitrogen, and the humidity and oxygen content will
gradually decrease. When nitrogen is continuously charged, the pressure in the
cabinet will also rise, which will compress the sealing strip and make the
original air quickly replaced.In addition, note that the pressure of the
external nitrogen should not be too large, and the specific use should be
adjusted according to the N2 cabinet specifications.

What's the application of Dry Nitrogen Storage Cabinets
Nitrogen gas storage cabinets have several applications in laboratory settings,

Preservation of sensitive materials:
Many materials, including chemicals, electronic components, and biological
samples, can be sensitive to moisture, oxygen, or other contaminants in the
air. By storing these materials in a N2 cabinet, they can be protected from
exposure to these contaminants, preserving their integrity and stability over

Chemical reactions:
Some chemical reactions can be sensitive to oxygen or other gases in the air,
and require an oxygen-free environment to proceed properly. Nitrogen cabinets
can be used to create these environments, allowing researchers to conduct
experiments with greater precision and control.

Semiconductor manufacturing:
In the production of electronic components, such as microchips and printed
circuit boards, it is important to avoid exposure to moisture and other
contaminants that can damage the materials. Nitrogen cabinets can be used to
create a controlled, clean environment for manufacturing these components,
improving their reliability and performance.

DNA sequencing:
In DNA sequencing, it is important to maintain the stability and integrity of
the DNA samples throughout the sequencing process. Nitrogen cabinets can be
used to store and protect these samples, ensuring accurate and reliable

Overall, nitrogen desiccant storage cabinets are an essential tool for
researchers and scientists who need to protect sensitive materials and maintain
a controlled environment for their experiments and processes.
