MicroRhizons

pore water samplers for the RhizonBox



overview

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 steam-sterilize them.

 

RhizonBox

RhizoboxRhizonBoxes for a direct sampling of soil moisture in the rhizosphere during growth experiments or root research.

In the front plate, there are 2183 holes with a lateral distance of 5 mm, which allow direct sampling near the roots with MicroRhizons.

The dimensions of the RhizonBox are: height 33 cm, width 22 cm, depth 4 cm.
