1. A device for vacuum stoppering a medical container, comprising:
a main body having a proximal end, a distal end, and a sidewall defining an internal volume comprising a variable pressure chamber configured to be connected to a vacuum pump;
a stopper holder system arranged in communication with the variable pressure chamber, wherein the stopper holder system comprises at least one blocking element that receives and holds a stopper in a fixed position relative to the main body and prevents movement of the stopper in a proximal direction within the main body;
a piston rod moveable inside the internal volume of the main body along a longitudinal axis between a proximal rest position wherein the piston rod is remote from the stopper and a distal operative position wherein the piston rod contacts and pushes the stopper; and
a container holder system, arranged distally relative to the stopper holder system and in communication with the variable pressure chamber, the container holder system being configured to receive an end of a medical container and to hold the medical container aligned with a direction of travel of the piston rod such that movement of the piston rod pushes the stopper from the stopper holder system into the medical container.
