Sample extracting, diluting and discharging device

Abstract

A tube for mixing, diluting and preserving a sample includes a hollow first container for receiving and storing a solution, the first container having first and second ends, wherein at least the first end has a through-hole, and a transport-pin located in the through-hole of the first end having a shape closely matching to the through-hole, the transport-pin including a recess with a predetermined size. The recess is suitable to be filled by a sample, wherein the transport-pin is movable between an initial position in which the recess is positioned at least partially on the outer side of the first container, and an end position in which the recess is positioned at least partially on the inner side of the first container.
