In which fields can biosafety airtight transfer Windows be used?

The biosafety airtight transfer window is a device used for transferring items between different clean areas or biosafety level areas while ensuring that the air environment within the area is not contaminated. It has strict airtightness and disinfection functions. Its application fields are extensive, mainly including the following aspects:
I. Biomedical Field
Biological laboratory (BSL-2/BSL-3, etc.)
It is used to transfer experimental samples, reagents, consumables, etc. in high-level biosafety laboratories (such as those studying viruses, bacteria, and other pathogens), prevent harmful microorganisms from leaking into the external environment, and protect the safety of laboratory personnel and the public.
Typical scenarios: COVID-19 sample testing, vaccine research and development laboratories, etc.
Pharmaceutical workshop
Transfer raw materials, excipients, packaging materials, etc. in sterile drug production workshops (such as injection and biological preparation production lines) to prevent external contaminants from entering the clean area and ensure that drug quality meets GMP standards.
It can be combined with functions such as ultraviolet disinfection and ozone disinfection to sterilize the surface of the transferred items.
Ii. Medical and disease control field
Hospital Infectious Disease Department/Infectious Disease Ward
It is used for the transfer of medicines, food, medical waste, etc. between isolation wards (such as wards with infectious diseases like COVID-19 and tuberculosis) and external clean areas, reducing direct contact between medical staff and patients and lowering the risk of cross-infection.
The airtight design can prevent the leakage of polluted air in the ward. Combined with an efficient filtration system (such as HEPA filtration), it ensures the unidirectional flow of air.
Microbiology Laboratory of the Center for Disease Control and Prevention
Transfer infectious samples (such as blood and secretions) to the testing area, and at the same time meet the item transfer requirements between the biosafety cabinet and the laboratory, in compliance with the "Regulations on Biosafety Management of Pathogenic Microorganism Laboratories".
Iii. Food and Cosmetics Industry
Clean workshop for food processing
Transfer raw materials, packaging containers, etc. in high-cleanliness food production environments (such as baking, dairy, and canning workshops) to prevent dust and microbial contamination of food and meet the requirements of the HACCP food safety system.
For example: transferring baking ingredients into the aseptic filling room, or transferring finished products to the packaging area.
Sterile production workshop for cosmetics
Transfer the paste raw materials, packaging bottles, etc. into the aseptic filling area to prevent microbial contamination and product deterioration, which complies with the Good Manufacturing Practice for Cosmetics (GMPC).
Iv. Electronics and Precision Manufacturing Field
Semiconductor clean workshop
Transfer wafers, chips, precision electronic components, etc. into ultra-clean environments (such as Class 100 / Class 1000 clean rooms) to prevent particulate pollutants in the air (such as dust and metal ions) from affecting product yield.
The airtight design can maintain a positive or negative pressure environment in the workshop, and in combination with the air shower function, it can remove the particles adhering to the surface of the items.
Production of precision components for aerospace
High-precision mechanical parts, electronic components, etc. are delivered to the dust-free assembly room to ensure that the products are assembled in a pollution-free environment and meet the strict standards of the aerospace industry.
V. Agriculture and Bioengineering
Animal Disease Detection Laboratory
Transfer animal tissue samples, sera, etc. to the testing area to prevent the spread of pathogens such as avian influenza and African swine fever and protect the safety of the breeding environment.
Biosecure livestock and poultry farms
The transfer of feed, veterinary drugs, etc. between the feed storage area and the breeding area in the breeding farm can prevent the spread of foreign pathogens through items, which is particularly suitable for the prevention and control of highly pathogenic diseases (such as foot-and-mouth disease).
Plant Tissue Culture Laboratory
Transfer explants, culture media, etc. into the sterile culture room to prevent contamination by miscellaneous bacteria and affect the survival rate of tissue culture seedlings. It is often used for the rapid propagation of flowers and seedlings without virus.
Vi. Other special scenarios
The field of nuclear biosafety
In laboratories involving radioactive microorganisms or nuclear contamination, transfer protective equipment, testing devices, etc., to prevent the dual leakage of radioactive substances and biological hazards.
Customs and Inspection and quarantine
In the port laboratory, imported food, animal and plant samples, etc. are transferred. When conducting pest and disease detection, it is ensured that foreign harmful organisms (such as invasive species and quarantine microorganisms) do not spread into the domestic environment.
Core functions and advantages
Air tightness control: Through devices such as sealing strips and pressure sensors, it ensures that the air pressure difference between the two sides remains stable during the transmission process, preventing air backflow.
Disinfection and sterilization: Integrated with disinfection modules such as ultraviolet lamps, ozone generators, and hydrogen peroxide sprays, it rapidly sterilizes the surfaces of transferred items.
Intelligent management: Some high-end products support PLC control systems, which can monitor parameters such as pressure, temperature and humidity, and disinfection time in real-time, and record operation logs to meet compliance requirements.

The selection of biosafety airtight transfer Windows needs to be designed based on the biosafety level (such as BSL-2/3), cleanliness level (such as ISO 5-8), and the characteristics of the transferred items (such as size and temperature sensitivity) of the specific application scenarios to ensure a balance between safety and efficiency.
