Abstract

Pour réduire l'effort d'emmanchement d'un cône de prélèvement (8) tout en assurant une étanchéité et un maintien satisfaisants, l'invention a pour objet un embout porte-cône de prélèvement (6) pour pipette, comprenant deux portions (32, 38) de maintien du cône (8) formant chacune saillie sur la surface extérieure (34) de l'embout et étant espacées l'une de l'autre selon une direction axiale de l'embout, l'embout comprenant également un joint à lèvre (20) destiné à contacter le cône (8) et agencé axialement entre les deux portions de maintien (32, 38).To reduce the fitting force of a sampling cone (8) while ensuring satisfactory sealing and retention, the invention relates to a sampling cone holder tip (6) for a pipette, comprising two portions ( 32, 38) for retaining the cone (8) each forming a projection on the outer surface (34) of the nozzle and being spaced from one another in an axial direction of the nozzle, the nozzle also comprising a lip seal (20) intended to contact the cone (8) and arranged axially between the two retaining portions (32, 38).
