The SPT-W204 water sample alpha beta microwave evaporator utilizes the characteristic of internal heating of microwave energy molecules to achieve rapid concentration and enrichment of water samples, revolutionizing traditional electric heating plate heating. It is a good helper for pre-treatment of total alpha and total beta radioactivity detection in natural freshwater, tap water, mineral water, and drinking water.

Widely used in nuclear and radiation safety monitoring departments, disease control centers, occupational disease prevention and control institutes, entry-exit inspection and quarantine, nuclear industry research institutions, nuclear geology, nuclear power plants, nuclear science related research institutions, third-party testing companies and other related fields.
