Preparations: Ensure that the static passbox is clean and free from any residues or particles. Verify that the passbox's HEPA filters and other components are in good condition. Place the materials to be transferred into the passbox.
Access and Loading (Clean Area Side): Open the access door on the clean area side of the passbox. Place the materials inside the passbox, ensuring they are properly positioned and not obstructing the opening.
Door Closure (Clean Area Side): Close and lock the access door on the clean area side of the passbox. Make sure the door is sealed tightly to prevent any leakage of contaminants.
Material Transfer: If applicable, engage any interlock mechanisms that prevent both doors from being opened simultaneously, ensuring that only one door can be opened at a time. On the non-clean area side, open the access door to access the materials placed inside the passbox.
Access and Unloading (Non-Clean Area Side): Retrieve the materials from the passbox through the access door on the non-clean area side.
Door Closure (Non-Clean Area Side): Close and lock the access door on the non-clean area side of the passbox. Ensure the door is properly sealed to prevent contamination from entering the clean area.
Cleaning and Maintenance: After use, clean and sanitize the passbox, both internally and externally, to prevent cross-contamination. Regularly check and replace HEPA filters as needed to maintain proper filtration efficiency.

Pharmaceutical Industry:
Sterile Material Transfer: Static passboxes are used to transfer sterile raw materials, packaging components, and finished products between controlled areas in pharmaceutical manufacturing facilities.
Cleanroom Environments: They facilitate the movement of materials, tools, and equipment in pharmaceutical cleanrooms while maintaining aseptic conditions.
Microelectronics and Semiconductor Manufacturing:
Tool and Equipment Transfer: Static passboxes help transfer sensitive equipment, wafers, components, and tools between different cleanroom areas in semiconductor fabrication facilities.
Food and Beverage Industry:
Ingredient Handling: Passboxes ensure the hygienic transfer of raw ingredients, additives, and packaging materials between controlled and non-controlled areas in food processing facilities.
Biotechnology and Life Sciences:
Laboratory Sample Transfer: Static passboxes are used to transfer biological samples, reagents, and research materials between different laboratory areas while maintaining controlled conditions.
Research and Development: Controlled Environments: Passboxes facilitate the movement of sensitive materials, chemicals, and equipment within research labs, isolators, and cleanroom settings.

Contamination Control: Designed to prevent the transfer of contaminants between controlled and non-controlled environments, ensuring product and personnel safety.
Materials Transfer: Facilitates the safe and controlled transfer of materials, samples, tools, and equipment between different areas with varying cleanliness levels.
Bi-Directional Access: Equipped with doors on both sides to allow access from both the clean and non-clean areas.
Interlock Mechanisms: Often includes interlock systems to ensure that only one door can be open at a time, preventing simultaneous opening and maintaining controlled conditions.
Air Filtration: Some models feature built-in HEPA or ULPA filters that help maintain air cleanliness by filtering particles and contaminants from the air passing through.
Stainless Steel Construction: Many passboxes are constructed from stainless steel, which is durable, corrosion-resistant, and compatible with cleanroom and controlled environment requirements.
Transparent Windows: Some passboxes feature transparent windows or viewing panels that allow personnel to observe the material transfer process without opening the doors.
Gasket Seals: Equipped with airtight gasket seals around the doors to prevent air leakage and cross-contamination.
