The structure has an outer wall that defines an interior space therein. The outer wall defines a plurality of openings. A membrane is disposed around the outer wall at least in the area of the upper portion of the structure and is configured to allow at least one first selected type of molecule to pass therethrough. A reservoir mechanism is coupled to a bottom portion of the structure and is configured to define a reservoir in the lower portion of the structure that prevents a selected liquid from flowing out of the lower portion of the structure."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Diffusion sampler","description":"A diffusion sampler includes an elongated tubular structure, a first coupling device, at least a first membrane and a reservoir mechanism.
