PRENART SUPER QUARTZ
New improved version with better hydraulic conductivity and bubble pressure. New production procedure.
the "perfect" soil water sampler
The new PRENART SUPER QUARTZ soil water sampler combines the inert character
of PTFE with the good hydrological conductivity of silica flour in a unique way.
The sampler works in all soil types, in all depths and under all conditions.
All samplers are tested individually.
No contamination
The contamination from the PRENART SUPER QUARTZ sampler exposed to absolute clean
water is below the detection limit for all elements.
No retention
The PRENART SUPER QUARTZ soil water sampler does not
retain phosphorus, TOC or other elements like similar samplers made of
ceramic or porcelain do.
