The invention relates to a tube for mixing, diluting and preserving a sample, comprising 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 comprising 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. The invention also relates to a discharge device for controlling discharge of the diluted sample via a discharge port, this device having a discharge-opening for discharging the diluted sample and a second fitting element, that cooperates with a first fitting element to mount the discharge device on the first container, wherein at least a portion of the discharge device is moveable between at least two positions. The invention further relates to a sample pin in combination with the said tube. |
