Fluid reservoir

摘要

The invention relates to a fluid reservoir, in particular a fluid reservoir to be integrated into a miniaturized flow cell, comprising a reservoir space, which is enclosed by two bodies (6,7) that lie against each other in a fluid-tight manner. According to the invention, in addition to a stored liquid (9), a solid filling body (12) that fills the remaining reservoir space is arranged in the reservoir space. A part of the reservoir space filled by the stored liquid is preferably bounded predominately by one of the two bodies (6,7) and the solid filling body (12).

主权项

1. A fluid reservoir in a miniaturized flow cell, comprising: two bodies, one of the bodies having an indentation, the bodies being arranged to rest against each other in a fluid-tight manner so as to enclose a reservoir space in the indentation by covering the indentation in the one body with the other of the bodies; and, a solid filling body arranged in the reservoir space, in addition to a stored liquid, so that the solid filling body fills out a remaining capacity of the reservoir space not occupied by the liquid, and prevents formation of a residual air cushion caused by a curved liquid meniscus when covering the indentation with the other of the bodies, the solid filling body being a separate element from the two bodies.
