Netherlands Rhizon soil moisture sampler is a world-renowned soil science industry a standardized small instruments, including a variety of models that can be a variety of soil conditions, soil moisture collecting sampling operation. This sampler is part of the core technology is the sampling head with a porous membrane, automatic wet, it does not produce adsorption, but also to avoid cross-contamination. Wet sampler The horizontal placement in moist soil, in water as a lubricant during insertion. 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 Rhizon 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. Sampler consists of three parts: the front end of a hydrophilic porous membrane consisting of white sampling head (Porous part, a diameter of 2.5mm, an average pore size 0.15um, there are reinforcing filaments, there are two sizes 5cm and 10cm), no middle transparent extension tube (Extension Tube, made of PE / PVC pipe length can be customized), the end of the joint (Male luer lock, luer positive for connecting tube; Female luer lock syringe negative Luer connector for connection ). To insert a cylindrical pots or other containers filled with soil in the process, you can choose RHIZON FLEX-type soil solution samplers used to collect disturbed soil moisture (solution) for the analysis of trace elements and a large number of elements, dissolved oxygen and dissolved gases organics. 19.21.25 RHIZON FLEX, sampling head is 10 cm, nylon reinforced wire, 60cm long PVC extension tubes, positive joints, can be connected to the vacuum tube. 19.21.25F RHIZON FLEX, sampling head is 10 cm, nylon reinforced wire, 60cm long PVC extension tube, female connectors can be directly connected syringe. 19.21.26 RHIZON FLEX, sampling head is 5 cm, reinforced nylon line, 60cm long PVC extension tubes, positive joints, can be connected to the vacuum tube. 19.21.26FRHIZON FLEX, sampling head is 5 cm, reinforced nylon line, 60cm long PVC extension tube, female connectors can be directly connected syringe.
