About Filter Monitor
This paper will deeply study the filter monitor of different materials (filter membrane + filter cup),analyse their applicability and advantages and disadvantages under different experimental conditions.Through a detailed discussion, we aim to provide the experimentalists with scientific evidence in material selection,Help them to make informed decisions in the experimental design to achieve the best performance of the experimental results and ensure the safety of the experimental process.
