The suction pressure soil solution sampler is used for in-situ extraction of soil solutions from different layers in the field, and is widely used in agricultural production and scientific research. It is of great significance for environmental pollution monitoring, sewage utilization and other fields.

1.Adopting pre negative pressure suction method and31mmLarge ceramic head, quick sampling.

2.Two methods can be used to extract the solution extracted from the tube: positive and negative pressureliquid.

3.It can be used continuously or repeatedly.

4.No need to take soil for decomposition, no need to damage the on-site structure.

1The suction type soil solution sampler can be buried at any point, with a maximum depth of up to 15 meters.

2Choose the appropriate length of the sampler as needed and possible, typically 15cm，30cm，45cm，60cm，90cmAnd 120cm.

3Ceramic head diameter 31mm，Approximately 7 in lengthcm；Drill with a diameter of 32 at the square where soil solution needs to be extractedmmInsert the sampler vertically into a hole of appropriate depth, paying attention to leaving a height of the meter. 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.

4Use a water stop (gas) ring to clamp the water outlet rubber pipe and seal it.

5Insert the manual air pump interface into the air pressure tube port and evacuate the gas in the sampling tube to 80-100Kpa. Bend the gas rubber tube using the same method and seal it with a gas stop ring. Remove the air pump interface, and at this time, maintain negative pressure inside the sampler.

6For most soils, a soil solution can be obtained after a few hours. For very dry soils, it may take several days or repeated operations to obtain a solution sample.

7When extracting the solution, insert the manual air pump interface into the air pressure pipe port and release the water stop ring of the outlet pipe. Inject positive air pressure into the air pressure pipe and place a pre prepared container under the outlet rubber pipe. When the air pressure reaches a certain level, the solutioncanAutomatically flowing out.
