Abstract: An improved apparatus for collecting atmospheric samples, particularly air samples, comprises a sealed first container filled with liquid such as water, a sealed second container positioned below the first container, a vent in the first container which allows the atmosphere surrounding the apparatus to enter the first container at a controlled rate, and a vent from the second container for dispersing the atmosphere contained within the second container into the surrounding atmosphere at a controlled rate. A flow channel between the first and second containers allows the liquid in the first container to pass into the second container. Passage of the liquid from the first container to the second container creates a vacuum in the first container whereby a stream of air from the surrounding atmosphere is drawn at a controlled rate through the first container vent and into the first container where it is retained. Samples may be withdrawn from the first container through the use of a hypodermic syringe.
