standard rhizon samplers
soil pore water suction lysimeters
overview
- 2.5mm diameter, 5cm or 10cm length, a mean pore size of 0.15 µm, and yield of water of approx. 4 mL/minute
- Ideal for sampling macro and micro elements, dissolved gases and DOC
- Ideal for soils in pots, vessels, columns, cylinders with disturbed or undisturbed profiles
- Ideal for soil columns research
There are 4 types of standard Rhizon samplers, each with its own characteristics:
| standard Rhizon |
environment | for analyzing | type of strengthener |
| Rhizon SMS | disturbed soils, lab, greenhouse, and in upper layer in the field | macro elements, not suitable for analyzing metals and carbon | SS 316 strengthener wire
which can be bent permanently |
| Rhizon MOM | disturbed soils, lab, greenhouse | macro and micro elements, dissolved gases and DOC | glass fiber wire |
| Rhizon CSS | direct sampling in cores and undisturbed sediments | macro and micro elements, dissolved gases and DOC | glass fiber wire |
| Rhizon Flex | disturbed soils, only fit to position during the filling of the pots or cylinders | macro and micro elements, dissolved gases and DOC | nylon wire |
Each Rhizon type is available in 4 varieties:
- with a 5 or 10 cm porous part - using Rhizons with a 10 cm porous part, the yield of water is approximately 4 ml/minute
- with a male luer lock, suitable for creating a vacuum with needles + vacuum tubes, or with a female luer lock, suitable for creating a vacuum with syringes
female luer lock-type of sampler:
male luer lock-type of sampler:

sampling accessories
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.
