Vacuum blood collection tubes are sterile disposable containers used for blood collection, transportation, and storage of biological samples. They are widely used in modern laboratory diagnostics to ensure accurate and safe blood sampling.

Thanks to the pre-created vacuum inside the tube, the required amount of blood is automatically collected, reducing the risk of errors and improving the quality of laboratory testing.

Main Advantages of Vacuum Tubes

• accurate blood volume collection;
• high sterility level;
• reduced contact between medical staff and biological material;
• lower risk of hemolysis;
• fast and comfortable blood collection;
• compatibility with modern laboratory analyzers;
• convenient labeling and transportation.

The color of the tube cap indicates the type of additive or reagent inside the tube and its intended laboratory application.

Most Common Types:

• Purple cap — EDTA tubes for hematology;
• Blue cap — sodium citrate tubes for coagulation tests;
• Red cap — plain tubes or clot activator tubes;
• Green cap — heparin tubes for biochemistry;
• Gray cap — glucose and lactate testing;
• Yellow cap — gel separator and clot activator tubes.
