Rhizosphere Research Products B.V. products

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.

Basic characteristics: Microfiltration membrane with a nominal pore size of 0.12 - 0.18 µm. Hydrophilic membrane composed of a blend of polyvinylpyrrolidine and polyethersulfone. Structure asymmetric/microporous. High performance and a very good anti-fouling behaviour. Suitable for filtatrion outside-in and inside-out.

MicroRhizons are mainly used in RhizonBox and agar tests. They consist of two parts: a porous part of 8 mm with an outer diameter of 1 mm, and PEEK tubing with a connector fit to a syringe. The yield of MicroRhizons is up to 2 ml. As the tubing of MicroRhizons consists of PEEK and a special glue, it is possible to steamsterilize them.

RhizoCera, made from pure Al₂O₃, are the type of Rhizons to use when mechanical strength is important, for instance when there are stones, gravel or cracking soils, or when rodents or biting insects are present. Like other Rhizons, RhizoCera are non-destructive and can be used in saturated and unsaturated soils.
