Abstract:
1. A capillary for use in a capillary-flow cytometer, the capillary comprising: a wall defining a bore extending in a longitudinal direction, the wall further comprising: a substantially non-reflective inner wall surface defining a cross-sectional shape of the bore, the cross-sectional shape of the bore being traverse to the longitudinal direction of the bore and lacking point symmetry; and an outer wall surface defining a cross-sectional shape of the wall that is traverse to the longitudinal direction; wherein the cross-sectional shape of the wall is the same as the cross-sectional shape of the bore; and wherein the capillary is configured so that upon installation in a capillary-flow cytometer, substantially all light collected by an optical collection system of the capillary-flow cytometer passes through a side of the outer wall surface that is closest to the optical collection system.
