Serving as an Ecolav compliant dispenser increases the safety of the serum.
Note: However, this sterility is not 100%, as the mini-spike has a slight slack. You can use the green cap on the mini-spike to serve as a wedge. To do this, cut with the scissors or x-ato, the tip of this green cap, to open a hole and let it stay on the mini-spike. Insert the minis-pike into the serum with the lid, this way it will fit more.
