Micro Rhizon rhizosphere solution agar sampler designed simulation experiments. Applicable to its tiny rhizosphere and indoor simulation agar solution sampling. For example, studies of microbial metabolism in a petri dish, extract metabolites; seed germination extract root exudates or allelopathic substances. General solution of the sample volume of about 2ml. Can be used with RhizonBox use. RhizonBox root box, with MicroRizon use. The device must comply with MicroRhizon use, RhizonBox RHIZOBOX high 33cm, width 22cm, thickness (front spacing) 4cm, in order to facilitate the experimental observations and accurate sampling, the anterior wall of transparent glass design, there are 2210 drill hole diameter of 0.6mm, hole spacing 5mm, after the soil matrix as quartz sand, perlite, vermiculite, rockwool, peat and other implanted with experimental materials, such as wheat, corn, rice, eggplant, peppers, cucumbers and so on. Can be easily and accurately extract the different growth stages, root exudates of different sites. 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????
