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 as a white porous membrane composed of a hydrophilic 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 color transparent extension tube (Extension Tube, made of PE / PVC pipe, the length can be customized according to needs), the end of the joint (Male luer lock, luer positive for connecting tube; Female luer lock connector for connecting the negative Ruhr syringe). Rhizosphere sampler provided are the following types: SMS, MOM, CSS, Flex, MacroRhizon, MicroRhizon and Rhizon Box, in addition there is a RhizonCera, sampling head for the ceramic material. Main purpose: Rhizon soil moisture samplers are very suitable for pots, soil column studies (CSS used for undisturbed soils, sediments, such as acquisition, Macro Rhizon field for field trials, MicroRhizon for agar or RhizonBox). If you need to work with a soil sample several soil solution can also be used Rhizon soil moisture sampler. Thus the following research:? Soluble plant nutrients such as nitrate uptake root exudates allelochemicals research, such as soluble soluble metal content in soil transport in soil salinity accumulation of environmental protection (water lake sediments????? matter) Performance advantages:? situ extraction, destruction of soil hydraulic properties of the smallest of small dead volume, ion exchange capacity of less than 0.5 ml minimal (less than soil) PH value unchanged after sampling low price????
