A fluid dispenser and leachate collector used in a system for obtaining a soil sample, dispensing liquid into the soil sample, collecting the resulting leachate, and extracting a soil layer from the obtained soil sample. The fluid dispensing unit may be cylindrical in shape and include a perforated disc therein as well as bladed disc situated on top of the perforated disc. The bladed disc is rotatable on the perforated disc to expose or cover select patterns of perforations allowing for different fluid flowrates through the soil sample. The fluid dispensing unit may contain a nanoparticle suspension and a magnetic stirring system be used to mix the nanoparticle suspension. A pump may be included for dispensing the fluid in a top-down or bottom-up configuration. The fluid dispensing unit may include a threaded mating interface allowing for direct coupling onto the sample tube.

Fluid dispensing unit and collection unit for system of observing soil samples

A system for obtaining a soil sample, dispensing liquid, such as a nanoparticle suspension, into the soil sample, collecting the resulting leachate, and extracting a soil layer from the obtained soil sample. A sample tube is used for obtaining and holding a soil sample, and includes a removable section and stationary section joined in sliding relation to each other. A fluid dispensing unit is configured to attach to the sample tube to dispense fluid through the soil sample and may include a magnetic stirrer, pump, and different flow rate configurations. A collection unit attaches to the sample tube and collects the resulting leachate. A soil layer extraction tool holds the sample tube, creates an opening in the sample tube exposing the soil sample, and extracts a layer of soil for analysis using extractor blades. The extractor blades include an upper blade and lower blade connected by a vertical blade.

System and methods for observing soil samples

A sample tube is disclosed in a system for obtaining a soil sample, dispensing liquid into the soil sample, collecting the resulting leachate, and extracting a soil layer from the soil sample. The sample tube includes a removable section and stationary section joined in sliding relation. The removable section includes a first vertical wall, second vertical wall, and top ring. The stationary section has openings covered by the first vertical wall and second vertical wall of the removable section. Stabilizing means such as flanges are included for preventing rotation of the removable section within the stationary section. The flanges contact sides of the removable section. A drilling head and T-shaped handle may attach to the sample tube for extraction of a soil sample.

Sample tube for system of observing soil samples

A soil layer extractor tool used in a system for obtaining a soil sample, dispensing liquid into the soil sample, collecting the resulting leachate, and extracting a soil layer from the obtained soil sample. The soil layer extractor tool includes a base, a holder for a sample tube, and crane for lifting walls of the sample tube to expose a soil sample within the sample tube. The base includes a lower base portion and upper base portion joined in sliding relation. Vertical posts are mounted on the upper base portion, and extractor blades are mounted on the vertical posts for extracting a soil layer. The extractor blades include a lower blade and upper blade, and a vertical blade positioned therebetween. A soil layer is extracted by a sliding movement pushing the extractor blades into the exposed soil sample thus removing a soil layer from sample contained in the sample tube.
