Negative pressure soil solution sampler

Application of Soil Solution Sampler/Soil Solution Sampler:
The negative pressure soil solution sampler is used for in-situ extraction of solutions from different layers of soil in the field, and is widely used in agricultural production and scientific research. The monitoring of environmental pollution and the rational utilization of groundwater are of great significance.
Characteristics of Soil Solution Sampler/Soil Solution Sampler:
Adopting pre negative pressure suction method for quick sampling. The solution drawn from the tube can be extracted using both positive and negative pressure methods. Continuous use, no need to take soil for decomposition, and no damage to the on-site structure.Instructions for using soil solution sampler/soil solution sampler:
The negative pressure soil solution sampler can be buried at any location, with a maximum depth of 15 meters. Choose the appropriate length as needed and possible, generally 15CM, 30CM, 45CM, 60CM, 90CM, 120CM. Drill holes of appropriate diameter and depth at the location where soil solution needs to be extracted, insert the sampler vertically into the hole, and pay attention to leaving a surface height. If the diameter of the soil drill is too large, the surface soil can be backfilled until the pipe wall is in good contact with the soil. If the soil is very dry, it should be moistened with water and placed at the bottom of the borehole to tightly wrap the ceramic head.
Insert the manual air pump interface into the air pressure tube port, extract gas from the sampler tube to 80-100kpa, remove the air pump socket, seal the rubber air port, and maintain negative pressure inside the sampler.

For most soils, soil solution can be obtained after a few hours, while for very dry soils, it may take several repetitions or longer periods of time.
When extracting the solution, insert the manual pump interface into the pressure pipe port and release the outlet pipe plug, inject positive pressure, and place a prepared container under the outlet pipe. When the pressure reaches a certain level, the solution will automatically flow out.
