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 low price unchanged after sampling 1.RHIZON SMS for???? rhizosphere soil solution collect, analyze a large number of elements, but not suitable for analysis of metal ions. Acquisition of non-saturated soil moisture can be continuously flows and establish permanent collection points. Rhizosphere soil solution samplers (Rhizon SMS). Acquisition of non-saturated soil moisture can be continuously flows and establish permanent collection points. Depending on the purpose, use polymeric tubes or ceramic cup, two sampling can have a variety of diameters and design, water extracted directly from the soil to maintain the status quo. 19.21.01 Standard equipment includes: long 10cm of soil moisture Rhizon sampler (with PVC / PE pipes, connectors and cover), the positive connector can be connected to a syringe. Short Small Rhizon 19.21.05 ?? soil moisture samplers with 5 cm porous material, the connection syringe connector to the extension tube and (black) polyethylene extension tube connectors. Especially for small pot and soil sampling column.
