Abstract
Official abstract text for this publication.
A bioinert piping (1) that has a flow path (2) provided inside and a main body portion (10) between end portions (8, 8) includes a resin tube (4) that forms an inner wall of the flow path (2) over an entire length of the flow path (2), and a metal tube (6) that accommodates the resin tube (4) inside so as to cover the outer peripheral surface of the resin tube (4) over at least an entire length of the main body portion (10). The metal tube (6) is plastically deformed toward an inner side so that the outer peripheral surface of the resin tube (4) and an inner peripheral surface of the metal tube (6) are in liquid-tight contact with each other.
First claim
Opening claim text (preview).
What is claimed is: 1. A bioinert piping that is used in an analysis device, and has a flow path provided inside, end portions, and a main body portion provided between the end portions, the bioinert piping comprising: a resin tube that forms an inner wall of the flow path over an entire length of the flow path; and a metal tube that accommodates the resin tube inside so as to cover an outer peripheral surface of the resin tube over at least an entire length of the main body portion, wherein the metal tube is plastically deformed toward an inner side so that the outer peripheral surface of the resin tube and an inner peripheral surface of the metal tube are in liquid-tight contact with each other, and in the main body portion, an outer shape of a cross section, which is perpendicular to the flow path, of the metal tube is plastically deformed into a polygonal shape. 2. The bioinert piping according to claim 1 , wherein in the main body portion, the cross section, which is perpendicular to the flow path, of the metal tube is plastically deformed into a hexagonal shape. 3. A liquid chromatograph in which constituent elements are fluidly connected by the bioinert piping according to claim 1 .
