Rhizons 2.5 mm, the standard Rhizons for pore water sampling

The standard Rhizon models all have a diameter of 2.5 mm and a mean pore size of 0.15 µm. They can be used for sampling pore water in pots, vessels or cylinders filled with settled soil, or directly in undisturbed cores.

New: Rhizons with pore size of 0.6 µm

We added a new product to our Rhizon family: Rhizons with a pore size of 0.6 µm. These Rhizons are only available with a female luer lock. Do you need a male luer lock? Order the adaptor 19.21.08M (accessories)

 

4 types of standard Rhizon samplers for soil moisture sampling

 

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 

male

female

N.B. The article number of Rhizons with female luer lock always ends with a F.

Rhizon SMS, for analyzing macro elements 

Rhizon SMS are samplers used to collect water for analyzing macro elements, however they are not suitable for analyzing metals. They can be used in disturbed soils, lab, greenhouse, and in the upper layer in the field. Rhizon SMS samplers have a SS 316 strengthener wire which can be bent permanently. All Rhizon samplers are sold per set of 10.

Sampling accessories for pore water sampling

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. Please contact us: info@rhizosphere.com.

Do you need something else?

Do you need another length of the porous part?
Or another length of tubing?
Or Rhizons with a sleeve?
