Overview

Dialysis based diffusion equilibrium (Peeper) is a fundamental method for obtaining wetland soil/sediment pore water samples. Zhigan Environment has innovatively launched the high-resolution thin-layer diffusion balance device (HR Peeper), which is a commercially available device that can achieve rapid and high-resolution sampling of pore water samples. It has been widely applied in the field of soil and water environment detection. $r $nHR Peeper high-precision diffusion balance technology for pore water sampling

3. Product advantages

（1）Short balancing time, only requires2Oh my god（48h）；

（2）High vertical resolution,5mmObtain a data;

（3）The sample volume is large, meeting the requirements for multiple element determination;

（4）The outermost layer is fixed with an ultra-thin filter membrane, which does not affect ion diffusion. After removal, it can ensure that the surface of the filter membrane is clean and does not contaminate the sample during sampling;

（5）The operation is simple and convenient, only requiring a pipette for quick operation.
