Abstract
A transfer port apparatus (10) is provided to enable a worker to transfer one or more objects through a sealed passageway provided in the apparatus (10) from one sealed chamber into another sealed chamber. Transfer port apparatus (10) is adapted to be coupled to a movable canister (12) and a stationary isolator (16). Expandable airtight seals (72, 120) are deflated, doors (30, 40) are removed and an object (20) is transferred into the airtight clean working environment established in the isolator (16) through the sealed passageway established in transfer port apparatus (10) following coupling of canister (12) to isolator (16) using transfer port apparatus (10). After the object (20) is moved, doors (30, 40) are replaced and expandable airtight seals (72, 120) are inflated creating a substantially airtight seal. Movable canister (12) can be uncoupled from the transfer port apparatus (10).
