Claim 13:
14. The microfluidic cell culture chip according to claim 8, further comprising a solid lower module, said solid lower module comprising
a lower unit which includes an upper face, a lower face, and at least one side face, the lower unit comprising at least one tubular-shaped duct comprising an upper orifice of diameter d4 having a third axis passing through the centre of said upper orifice and perpendicular to said support, and a lower orifice of diameter d5, and
a base,
said lower unit being integrated in said base, and forming a whole with said base,
a value of the diameter d4 of said upper orifice being greater than or equal to a value of the diameter d5 of said lower orifice, and said value of the diameter d4 being greater than or equal to the value of the lower diameter d2 of said at least one perforation,
said upper face of said lower unit comprising said upper orifice of the at least one tubular-shaped duct, and said lower orifice leading to, itself or by intermediate means, an outside of said base.
