Abstract: The invention concerns a syringe for injecting the content of a straw enabling the reading of data borne by the straw, even when it is ready for use. The straw is placed in a tubular body (12) of the syringe in a housing (30) wherein is provided at least a lateral window (38).
Abstract: A straw (1) for the conservation of small quantities of substances, in particular biological substances, having a segment of tube provided inside one end with a stopper including gel powder, characterized in that a proportion of the gel powder is replaced with dispersed nonabsorbent material, the stopper thus having a mixture of gel powder and dispersed nonabsorbent material.

Abstract: A method is disclosed of making a component consisting of a substantially cylindrical support through which there is a substantially coaxial orifice and a membrane welded to one end of the cylinder substantially perpendicularly to a longitudinal axis of the support. A substantially plane membrane is welded to one end of a support substantially perpendicularly to a longitudinal axis of the support and, after cooling, the support is torn off the membrane in a direction substantially perpendicular to the plane of the membrane so that a portion of the membrane substantially corresponding to the end of the cylinder remains welded to the support. The method can be applied to making two-part stoppers for straws, in which case the membrane is microporous, hydrophobic, impervious to liquids and permeable to gases and the support is an insert made from a material chosen from an elastomer material, a thermoplastics material and a thermoplastics elastomer material.

Abstract: A catheter for artificial insemination of birds includes a plastic tube obtained by extrusion, each of the tube ends is shaped such that the tube's internal diameter at its ends is reduced to a value ranging between two-thirds and three-quarters of the tube's internal diameter, the reduction being obtainable by cold forming at the extruder outlet.
Abstract: A method and a system are disclosed for filling a straw which is fitted with a stopper that is permeable to gases and impermeable to liquids and which has a diameter greater than or equal to approximately three millimeters with a liquid while it is vertical. A primary vacuum is established in the straw. The straw is then filled and a quantity of air remaining above the resulting column of liquid is evacuated, enabling homogeneous filling of the straw.
