Abstract
A fitting for coupling a capillary to another component of a fluidic device is disclosed. The fitting includes a ferrule configured for enclosing a front part of the capillary and for contributing to a fluidic sealing between the fitting and the other component; a ferrule chuck configured for enclosing a back part of the capillary; and a housing configured for accommodating at least a part of the ferrule chuck and for pushing the ferrule chuck against the ferrule.
Claims20
A fitting for coupling a capillary to another component of a fluidic device, the fitting comprising
- a ferrule configured for enclosing a front part of the capillary and for contributing to a fluidic sealing between the fitting and the other component;
- a ferrule chuck configured for enclosing a back part of the capillary;
- and
- a housing configured for accommodating at least a part of the ferrule chuck and for pushing the ferrule chuck against the ferrule;
- a microstructure formed as multiple microprotrusions on at least a part of a surface of the ferrule chuck for generating, upon tightening the fitting at the other component, a form fit with the enclosed back part of the capillary over a contact area between the ferrule chuck and the capillary.
The fitting according to claim 11, wherein the microstructure is formed on a circumferential inner surface of the tapering back section.
