Title: Test tube for separating blood serum
Inventor: ENDO MATSUO
IPC: B01L3/14
Filed: 1993-11-16
Abstract: PURPOSE:To make it possible to take out only the upper layer blood serum by forming a small diameter part at an appropriate position on the drum part of a test tube body and setting the inner diameter at the small diameter part such that the sum of surface tension and the atmospheric pressure is higher than the liquid pressure applied to the surface of at the small diameter part on the bottom side. CONSTITUTION:When a test tube 1 filled with liquid is inclined or turned upside down, the liquid closer to the inlet side than a small diameter part 2 formed on the drum part flows out from the inlet. But since the inner diameter (r) at the small diameter part 2 is set such that the liquid pressure being applied to the surface of the small diameter part 2 on the bottom face side 3 is lower than the sum of the surface tension of the liquid and the atmospheric pressure, the liquid closer to the bottom side 3 than the small diameter part 2 does not flow out of the small diameter part 2 but stays on the bottom side 3. This structure facilitates the blood serum sampling work without requiring any expensive blood serum separating medium.
