Abstract: A stackable bucket system for carrying multiple substances in different containers at the same time while holding a single handle. The stackable bucket system includes a first container and a second container, wherein the second container is adapted to receive the first container therein and removably couple thereto, with the second container being larger than the first. Each container comprises a base and a perimeter wall ending in a rim at an open top. Handles are included on each container and are pivotally affixed to opposing sides thereof. The handle of the second container is wider than that of the first container and is adapted to fit over top of the handle of the second container. A flange protruding outward from the perimeter wall of the containers is adapted to rest flush against the rim of the open top when of the adjacent container when installed.

Abstract: A fume hood includes a top, bottom sidewalls, front panel and a back panel that define an enclosed workspace. The fume hood also includes a movable sash for opening and closing an access opening. The fume hood may also include an air chamber having an inlet in the front panel. The air chamber includes a baffle system that evenly distributes the inlet air as the air travels through the air chamber. An unimpeded flow of air is discharged downward and away from the breathing zone of the technician and proximate to the sash to reduce the forward momentum of air trying to escape the fume hood. In an alternate embodiment, the fume hood also includes an alarm system to provide a visual and/or audible indication to the user of a working condition of the fume hood. The characteristics of the visual indication and the audible indication may vary depending on the position of the movable sash and the measured airflow from the discharge of the air chamber.

An unimpeded flow of air is discharged downward and away from the breathing zone of the technician and proximate to the sash to reduce the forward momentum of air trying to escape the fume hood. In an alternate embodiment, the fume hood also includes a pressure pipe for drawing a small quantity of air from the air chamber and directing a flow of air between the movable sash and the header panel. This flow of air from the pressure pipe increases the relative pressure difference between the movable sash and the header panel of the fume hood.
