FLUIDIC SYSTEM FOR PROCESSNG A SAMPLE FLUID

摘要

The invention relates to a fluidic system comprising at least one bead chamber (311) containing a lyophilized reagent (LB) and a reaction chamber in a cartridge. In one embodiment, a series of bead chambers with different lyophilized reagents may be provided such that sample fluid can sequentially pass through them. In another embodiment, bead chambers may be located on a movable carrier, for example a rotating carousel, from which they may selectively be connected to a reaction chamber in a cartridge. In still another embodiment, the bead chamber (311) may comprise at least one flexible wall (FW) allowing for a minimization of dead volume associated with the extraction of lyophilized reagent (LB).

主权项

1. A fluidic system for processing a sample fluid, comprising:
a cartridge including with at least one reaction chamber for processing the sample fluid; at least one bead chamber comprising a solid reagents selectively added to the sample fluid; wherein the at least one bead chamber comprises at least one flexible wall, and wherein said flexible wall bulges outward, increasing the volume of the bead chamber such that the sample fluid is drawn in when a reduced pressure is applied to an outside of the flexible wall, or pre-stretched.
