Rhizon soil moisture sampler we offer is very easy to use. The porous plastic material can be automatically wetting, standard 0.15 micron porosity. This sampler also includes a diameter of 1 mm in inner diameter composite pipe (inner tube is PE, the outer tube of PVC), and the connector cover, and a steel wire reinforcement. Sampling does not adsorb dissolved organic or inorganic. The sampler is placed in a horizontal wet moist soil. During insertion water as a lubricant. It is very small due to the interference of the soil, the soil can be quickly returned to normal, so the sample can maintain good contact with the soil. Standard R hizon soil moisture samplers should pass through undisturbed soil column walls and pots. After extraction with a syringe or a vacuum tube, the sampler can be placed under vacuum sampling. Purpose: Rhizon soil moisture samplers are very suitable for pots, cylinders and cylinder research (Macro Rhizon for field). If you need to work with a soil sample several soil solution can also be used Rhizon soil moisture sampler. Thus the following study: soluble plant nutrients such as nitrate uptake root exudates soluble components such as soluble allelochemicals Soils Study metal transport in soil salinity accumulation environmental advantages: in-situ extraction of soil hydraulic properties destruction minimum dead volume is small, less than 0.5 ml of ion exchange capacity of the smallest (less than soil) PH value after sampling the same low price Micro Rhizon rhizosphere solution samplers dedicated to indoor simulation sampling MicroRhizon applicable to its tiny rhizosphere and interior agar solution simulation test sample. There are two parts, the diameter of 1mm, length 8mm sampling head, PEEL tube and syringe connectors, general solution of the sample volume of about 2ml. 19.21.81 MicroRhizon diameter of 1mm, 0.8mm long porous sampling head with 0.6 * 0.4 mm PEEK tube glued together from PEEK tube top has a 0.1mm hole, PEEK diameter 1.6mm, length 5cm, can be steam sterilized. 19.21.82 MicroRhizon with 19.21.81 MicroRhizon Similarly, a diameter of 1mm, 0.8mm long porous dividing head with 0.6 * 0.4 mm PS tubes bonded together, from the top of the tube with a 0.1mm orifice, PS diameter 2mm, length 5cm, not steam sterilization.
