ABSTRACT
Analysis of microorganisms, capture of suspended particles and identification of chemical constituents are important for humans to understand and carry out the research on rivers, lakes, and oceans. To achieve this purpose, their water samples and the surface water should be easy to obtain, but it is difficult to collect water at a certain depth. The existing water samples are complex, expensive and difficult to operate. So, we decided to develop a water sampler with the advantage of collecting water quickly, simple production and obtaining multilayer water.
