Soil solution sampling system with 3 inert PTFE / QUARTZ porous probes.
This new soil solution sampler combines the inert characteristics of PTFE which prevents any external chemical contamination of the soil solution with the good hydrological conductivity of classic porous ceramics.
Key Advantages
NO CHEMICAL CONTAMINATION OF THE WATER SOLUTION
Disadvantages
Operating range : 0 to -500 mbars
FEATURES
The sampler works in all soil types, in all depths and under all conditions.
Made of unbreakable and durable materials.
Easy to install in the soil.
Frost resistant.
Can be reinstalled in new sites after rinsing.
Does not contaminate or retain elements or chemical compounds which might interfere with the collected samples (below detection limits, see table).
Samples are collected in bottles.
These collecting bottles also function as vacuum containers.
They are provided with a special polyacetal (POM) screw cap with PTFE gasket and fittings.
They can be installed and operated under all weather conditions without specific tools.
When mounted, the system is completely airtight.
All samplers, fittings and tubings are tested individually to ensure correct functionning and high quality.
