ABSTRACT:
Straws, in particular for artificial insemination of animals and storage of biological products, are filled by aspiration through a suction nozzle fitted with a needle which enters the straw to the rear of a composite stopper and is fitted with a seal. A biological product (diluted sperm) is drawn up a flexible elastomer tube to an injector nozzle in response to reducing the pressure in the straw. The flexible tube is held centered over a distance equal to at least five times its outside diameter in a hoop held in a support. The elastomer from which the flexible tube is made has a Shore hardness of 41 to 47 and a reversible elongation capacity of at least 250%. These arrangements ensure rigorous centering of the needle in the hoop despite the flexibility of the tube. Parts which have been in contact with the sperm can be discarded after all of a sample has been used up, rather than requiring costly cleaning.
