RRP-MicroRhizon samplers are mainly used in RhizonBoxes and agar tests. They consist of two parts: a porous part (i.e. microfiltration membrane) of 8 mm with an outer diameter of 1 mm, and PEEK tubing (0.6*0.4 mm; 12 cm long) with a connector fit to a syringe. The mean pore size of the porous part is 0.15 µm, hence no filtering of samples before analysing is required. The yield of MicroRhizons is up to 2 ml (depending on pore water availability). As the tubing of MicroRhizons consists of PEEK and a special glue, it is possible to steam-sterilise them. All Rhizon samplers are sold in sets of 10.

RPP-Rhizon samplers are used for (un-)disturbed soils (see types below), and are thus ideal to be positioned in Rhizoboxes and RhizonBoxes. Especially RhizonBoxes can be equipped with special openings on the side wall (e.g. at different depth) to insert special Rhizon samplers (with sleeve to prevent leakage of water from the RhizonBox) before or after soil filling. They can be used to collect water from larger zones (length of porous parts: 5 cm or 10 cm) for analyzing macro and micro elements, dissolved organic carbon (DOC) and dissolved gases. Using Rhizons with a 10 cm porous part, maximum yield of water is approximately 4 ml per minute.
