Intended Use
This tube is a sterile, single-use container designed for venous blood collection utilizing negative pressure. It automatically draws a precise volume of blood, ensuring standardized sampling for clinical laboratory testing.
Working Principle
The tube is pre-evacuated to a controlled negative pressure. When punctured by a blood collection needle, atmospheric pressure pushes blood into the tube automatically until the pressure inside equals outside, achieving accurate blood volume.
