TUBE TO AUTOMATICALLY HOLD URINE PRECIPITATE FOR QUANTITATIVE CENTRIFUGAL SEPARATION FOR URINE ANALYSIS

摘要

PROBLEM TO BE SOLVED: To provide a quantitative centrifugal separation tube which can smoothly and sanitarily be operated. ;SOLUTION: This quantitative centrifugal separation tube comprises a tube 1 having opened part 11 in one end, a truncated conical part 13 defining the conical hole 14 in the inside is formed in the lower part of the tube 1, a narrowed open part 141 is formed in the center part of the bottom of the truncated conical part 13 as to narrow the conical hole 14, and a bottom cap part 16 with a closed end and provided with a bottom part chamber 17 restricted in the inner part is positioned in the lower part of the truncated conical part 13 and formed in the most lower end of the tube 1. Consequently, in the case urine liquid is poured out of the tube 1 from the upper side, the urine liquid and the urine precipitate in the bottom part chamber 17 in the bottom part of the tube 1 are automatically kept in the bottom cap part 16 due to the surface tension of the urine liquid in the narrowed open part 141 of the conical hole 14 for sanitarily and precise urine precipitate inspection.;COPYRIGHT: (C)1999,JPO
