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

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.
