Definitions

  • the at least one fastening element and / or the at least one counter-fastening element can be designed as a magnetic fastening element.
  • a handle equipped with a magnetic counter-fastening element can be fixed to a base body which has a magnetism-responsive fastening element or a housing made of a magnetism-responsive material.
  • the fastener is a magnetic fastener
  • a magnetism-responsive handle or handle having a magnetically-responsive mating fastener also can be releasably secured to the body.
  • a mounting option can be provided, which does not require any undercuts and thus helps to prevent the accumulation of dirt between the handle and the base body.
  • the hand dosing device can be particularly comfortable in the hand lie when the body has a rounded, round or circular cross-section or even cylindrical.
  • the handle may have a handle shell, which surrounds the body in the position of use at least partially. In this way, the handle can be particularly ergonomically fixed to the body. Between the handle and the body flowing transitions may result in this way, due to which the hand-dosing can be particularly pleasant to grasp.
  • a negative pressure is generated at the plugged-on pipette tip, with the aid of which a defined volume of liquid dependent on the preset volume of the air cushion can be received in the pipette tip.
  • the volume of the air cushion can be predetermined by the volume adjustment means 14.
  • the shaft 16 is surrounded by a Abwerferhülse 20.
  • the ejector sleeve 20 can move relative to the shaft 16 in the direction of the free end 18 of the shaft 16 axially. This with the aim of dropping a mounted on the free end 18 of the shaft 16 pipette tip as needed.

Abstract

L'invention vise à ce qu'un dispositif de dosage manuel (1) en particulier une pipette (2), puisse être adapté à des mains de taille différente, À cet effet, au moins une poignée (5) ou une poignée interchangeable est ou peut être fixée de manière amovible au corps de base (3) du dispositif de dosage manuel (1). L'adaptation du dispositif de dosage manuel (1) à des utilisateurs ayant des mains de taille différente peut être effectuée en réduisant la poignée (5) ou en changeant la poignée (5) et en remplaçant la poignée (5) par une poignée (5) présentant des dimensions différentes.
