A fume hood is described for use in removing material from, or inserting material into, the opening of a container. The fume hood enclosure has a floor with an opening for insertion of the upper end of the container into the enclosure, with a flexible member around the periphery of the opening to form a seal between the container and the enclosure when the upper end of the container is inserted into the enclosure. A base is provided supporting the hood at a level permitting insertion of the containers beneath the opening in the floor. A vertically adjustable carrier is provided to raise the container to insert the upper end of the container into the enclosure through the opening.
