field soil pore water suction lysimeters
- Ideal for sampling macro and micro elements, dissolved gases and DOC
- Install to soils depths of 1.2m
- Easy to install with MacroRhizon Installation Tool
MacroRhizons are developed for field research. They have a porous part with an outer diameter of 4.5 mm and a pore size of 0.15 µm.
MacroRhizons are only available with female luer lock, suitable for creating a vacuum with syringes. The yield of water is approximately 20 ml/minute.
MacroRhizons have to be inserted at 30 to 45 degrees in an augured hole, or horizontal in the field, to prevent rain water infiltration along the PVC pipe directly to the porous part.

Before you can take your samples, you will need additional accessories to create a vacuum. This can be either a syringe or a vacuum tube. For field experiments, extension tubing might be useful. We could advise you about the best accessories for your experiments.
