Abstract

Clapet pour tube de séparation. Il comporte un corps cylindrique 28 dont une extrémité comprend un rebord 30 s'appliquant hermétiquement contre la paroi d'un tube collecteur 10. L'autre extrémité du corps 28 comporte un rebord annulaire intérieur 34 formant un siege et présentant une ouverture 46 qu'un organe mobile d'obturation peut fermer. Cet organe d'obturation tend à être maintenu en contact avec le rebord 34 par des pattes élastiques 48. Ces pattes 48 maintiennent l'organe d'obturation sous une certaine traction, même lorsqu'il est appliqué contre le siège. Domaine d'application : séparation des phases lourde et légère d'échantillons de sang, etc.
