Abstract
A device for collecting samples of water from wells and the like comprises an elongated container having valves at both ends which valves are arranged to open when the container is lowered in a body of water and to close when the container is stopped and to remain closed when the container is being raised to the surface. The device traps a sample of the water at the position at which the device is stopped, and the container is held closed during the entire return to the surface.
