Frequently Asked Questions

Sampling

What do I need for sampling?

For sampling pore water, you need a Rhizon sampler and accessories to create a vacuum. For Rhizon samplers with a female luer lock, you need a syringe. For Rhizon samplers with a male luer lock, you need a needle and a vacuum tube, or you can use a connector female luer lock and a syringe.

If you use syringes to create a vacuum, we advise wooden retainers to keep the vacuum.

I have installed the Rhizon, but it does not sample water.

Probably you forgot to remove the protection cap (blue or red). Remove it and install the Rhizon again.

Cleaning and reuse of Rhizons

Can I clean my Rhizons after the experiment and use them again?

No, all Rhizons are disposables.

However, if you rinse them with a weak acid (pH>3) and subsequently with demineralized water, you check them on leakage and you let them dry, you could use them again. Realize there might be cross contamination. Rhizosphere Research Products does not guarantee the reuse of Rhizons.
