Short summary

We have developed a new mobile automated water sampling device for environmental research and other applications where waters need to be tested for compliance with environmental/health regulations. It has two main advantages over similar devices: firstly, it injects water samples directly into airtight vials to prevent any change in sample properties through contamination, evaporation and gas exchange. Secondly, it can hold up to 160 sample vials, while other devices only hold up to 24 vials.
