A life sciences pass-through box is a tunnel-like structure for transferring materials between cleanrooms and adjacent rooms. It has doors on both ends to keep different atmospheres separate and prevent simultaneous opening. These boxes are easy to clean for cGMP use and resistant to cleaning chemicals. They might have features like timed locks, lights, and automatic doors. Some use sanitizing methods like sprays or UV light. Gaskets help limit air transfer, and ventilation methods vary based on purpose.
