An integrated needle piercable and self-healing septum is integrated in the sampling vessel interface
to the microfluidic chip. The sampling vessels with integrated septum allow for a safe sampling,
interfacing with a Luer on a microfluidic chip and the removal of the sampling vessel from the chip
after transfer of a certain amoutn of sample on chip. A needle embedded on chip allows the liquid
transfer from the septum on the chip. After the removal of the sampling vessel from the chip not liquid
can pour out from the septum. An additional cap to close the Luer interface of the septum further
ensures that contamination cannot occur.
