Abstract: A cart transports items between a controlled environment (e.g., a clean room or an airlock to a clean room) and an uncontrolled environment. The cart has a main body that carries the items, and a removable and interchangeable wheel base assembly. A first wheel base assembly is located in the uncontrolled environment and a second wheel base assembly is located in the controlled environment. The user can push the cart (with the first wheel base assembly) up to the second wheel base assembly at the boundary between the controlled environment and the uncontrolled environment. The user then unlocks the main body from the first wheel base assembly, slides the main body onto the second wheel base assembly, and locks the main body to the second wheel base assembly. An autoclavable storage and transport cart can hold several wheel base assemblies.

Abstract: A system and method for mixing and dispensing two substances are provided. The system includes: a first substance a first container for containing a first substance, a second container for containing a second substance, a feeding tube, and a pumping system connected to the first container, the second container, and the feeding tube; wherein the system comprises at least three modes of operation: combining the first and second substances into one combined substance, mixing the combined substance, and dispensing the mixed substance; and wherein the pumping system is adapted to perform the at least three modes of operation and dispense the mixed substance to the feeding tube.

Abstract: An air sampler device has a top plate and a bottom plate, and receives a Petri dish between the top plate and the bottom plate. The top plate includes 283 substantially small holes. The bottom plate has a deepened center well formed in the top surface. Elongated slots are formed in the top surface which extend out from the well. The slots have distal ends which extend beyond the Petri dish. Air is drawn into the sampler by a vacuum tube through an air port which communicates with the center well. Air is pulled into the 283 holes in the top plate and strikes the capture material in the Petri dish. The air then travels up over the sides of the dish, into the distal ends, through the slots, and into the center well, where it exits out of the vacuum air port.

Abstract: A mixing and dispensing apparatus having first and second containers. The first container has a main body portion which retains a first substance. A separate compartment is located in the first container and an internal passageway is formed between the main body portion and the compartment. The second container is configured to retain a second substance, and is compressible. The second container has a top end and a closed spout, wherein the closed spout is located in the compartment with the spout extending through the internal passageway into the main body portion of said first container. A release mechanism is formed by a plunger extending within the second container. The plunger has a first end in communication with the top end of the second container, and a second end aligned with the closed spout. The second end opens the closed spout when the second container is compressed to release the second substance into the main body portion of the first container.

Abstract: A method of performing a cleaning operation with an autoclavable bucketless cleaning system is disclosed.

Abstract: A gas sampler device has a top plate with a concaved outer wall. The concaved outer wall allows users easily to lift the top plate off of the bottom plate without disturbing the bottom plate because the curved surface permits more positive contact between the outer wall and users' fingers. Moreover, the weight of the top plate is reduced by approximately twenty percent compared to conventional top plates, a feature that also makes it easier for users to lift the top plate off of the bottom plate.
