Abstract
A water sampling device has a rigid body, a top lid, extension members, a horizontal member, a spring, a rod, at least one polymer membrane and a bottom lid. The top lid has a shaft attached to it and the shaft traverses through the horizontal member. The bottom lid is connected to the rod upon which the at least one polymer membrane is attached perpendicularly. The water sampling device undergoes two different stages of lid opening and closing while in operation of collecting water sample to concentrate diversified bacteria from different water depths. The top lid, the shaft and the spring co-operate with the rigid body and the horizontal member such that in a first state, the top lid seals the top end opening while in a second state allows fluid to flow to an inside portion of the rigid body.
