TESTING DEVICE FOR ANALYZING LIQUID SAMPLE WITH CAPILLARY TUBE WITH UNEVEN WIDTH

摘要

PROBLEM TO BE SOLVED: To provide a testing device which enables simple weighing of a sample and analyzing thereof simultaneously without separating the sample into another container nor making and fixing a reagent layer separately. SOLUTION: In this testing device 31, a reagent is held at a specified position within a capillary tube 33 having a test liquid introduction port 34 and an exhaust port 35 and a test liquid is introduced from the introduction port 34 to be reacted with the reagent so that a specified component in the test liquid is analyzed by the reagent. In this case, the capillary tube 33 has a first hydrophilic region 331 in which the test liquid is moved to the reagent from the test liquid introduction port 34, a second hydrophilic region 333 of a fixed area for holding the reagent and a hydrophobic region 332 which is arranged to separate the first hydrophilic region 331 and the second hydrophilic region 333 while communicating with the exhaust port not via the first hydrophilic region 331 and the second hydrophilic region. The width (d) of the capillary tube at the interface part of the second hydrophilic region 333 and the hydrophobic region 332 is narrower than the width D of the capillary tube within the second hydrophilic region.
