Workflow of the double cap

The double cap has a side where we can screw the water sample vial and a side for the bioreporter. The latter presents a connector, responsible to pierce a seal which protects the bioreporter vial. This seal looks like a seal on a yoghourt, and prevents the GMO realising into the environment.

This principle is summarized in this scheme :

The workflow to use the new kit is the following :

The bioreporter is prepared in the lab and the vial is sealed. Then the vial is closed by a cap for the transport.
Water is collected with a second vial.
The double cap is screwed on the water collection vial (side without connector).
After removing the cap, the bioreporter vial is screwed to the other side (with connector).
The two substances are mixed, the two vials stays fixed to one another by the double cap.
The GMO are returned to the lab to be destroyed.

We can summarize it with the following scheme :
