Abstract: The straw comprises a tube (11) and a stopper (12) fixed relative to the tube (11) and comprising a male connector tip (29) configured in order that a syringe needle (44) having a female connector tip (45) with a frusto-conical internal surface in accordance with a standard can be connected to said stopper (12) by engagement of the female connector tip (45) of the needle on the male connector tip (29) of the stopper (12). The injection device comprises such a straw (10) and a syringe needle (44). The method of emptying the straw comprises the step of pushing the dose of liquid-based substance (21) packaged in the straw (10) towards the stopper (12).

Abstract: A sheathing for packaging a predetermined volume of a biological substance designed to be immersed in a liquid cryogenic agent, the sheathing including a thin tube and a ballast associated with the thin tube.
