Vacuum Blood Collection Tubes Manufacturer & Supplier
Hawach is a professional manufacturer and supplier of high-quality vacuum blood collection tubes, designed for reliable, standardized venous blood collection in clinical laboratories, hospitals, and diagnostic centers worldwide.
Our vacuum blood collection tubes are sterile, pre-evacuated, and engineered to ensure accurate test results, sample stability, and safe handling. Each tube is formulated with specific additives or no additives to meet the requirements of hematology, clinical chemistry, coagulation, glucose testing, and other diagnostic applications.
Every tube type is defined by its additive system, which determines its clinical function, sample stability, and testing application.
Classification of Vacuum Blood Collection Tubes
Vacuum blood collection tubes are classified based on their additives and diagnostic functions into several main categories:
- Serum Tubes: Including serum separator tubes (gel tubes) and red top tubes, used for serum-based clinical chemistry testing
- Plasma Tubes: Heparin tubes used for plasma chemistry and emergency diagnostics
- Anticoagulant Tubes: EDTA tubes for hematology and citrate tubes for coagulation testing
- Special Purpose Tubes: Fluoride tubes for glucose testing and ESR tubes for inflammation monitoring
Each category is defined by its additive system, which determines whether the blood sample is processed as serum, plasma, or whole blood, directly affecting laboratory accuracy.
Complete Vacuum Blood Collection Tube Portfolio
Hawach provides a full range of vacuum blood collection tubes to cover all major clinical and diagnostic needs.
Serum Separator Tubes (Gel + Clot Activator)
- Applications: Clinical chemistry, liver function, kidney function, electrolyte testing
- Additives: Separator gel + clot activator
- Function: Forms a stable physical barrier between serum and blood cells after centrifugation, ensuring clean, high-purity serum samples.
Red Top Tubes (Plain / Clot Activator Tubes)
- Applications: Serum testing, clinical chemistry, serology, blood banking
- Additives: None (plain) or clot activator
- Function: Allows natural blood clotting or accelerated clot formation, providing serum samples for routine laboratory analysis without gel separation
EDTA Tubes (K2 / K3 EDTA)
- Applications: Hematology, CBC, blood smear, blood typing
- Additives: K2 EDTA or K3 EDTA
- Function: Chelates calcium ions to prevent blood clotting and preserve blood cell morphology.
Heparin Tubes (Lithium Heparin)
- Applications: Plasma chemistry, emergency biochemistry testing
- Additives: Lithium heparin
- Function: Inhibits thrombin activity to prevent coagulation while maintaining plasma component integrity.
Citrate Tubes (3.2% / 3.8% Sodium Citrate)
- Applications: Coagulation testing (PT, APTT)
- Additives: Sodium citrate
- Function: Binds calcium ions to prevent clotting, supporting accurate coagulation analysis.
Fluoride Tubes (Sodium Fluoride + Potassium Oxalate)
- Applications: Glucose testing, lactate testing
- Additives: Sodium fluoride + potassium oxalate
- Function: Inhibits glycolysis to stabilize glucose levels after blood collection.
ESR Tubes
- Applications: Inflammation monitoring, ESR testing
- Additives: Sodium citrate (fixed ratio)
- Function: Supports accurate erythrocyte sedimentation rate measurement.
How to Select the Right Vacuum Blood Collection Tube
Choosing the correct tube ensures diagnostic accuracy, reduces sample rejection, and improves lab efficiency.
- Serum testing → Serum separator tubes or red top tubes
- Hematology → EDTA tubes
- Plasma chemistry → Heparin tubes
- Coagulation testing → Citrate tubes
- Glucose testing → Fluoride tubes
- Inflammation testing → ESR tubes

Order of Draw (CLSI Standard)
To avoid cross-contamination and ensure accurate results, blood collection must follow the CLSI-recommended order:
- Citrate tubes
- Serum tubes
- Heparin tubes
- EDTA tubes
- Fluoride/oxalate tubes
Frequently Asked Questions
What are vacuum blood collection tubes used for?
They are used for standardized venous blood collection in clinical laboratories, providing precise blood volume, reducing contamination risk, and ensuring accurate diagnostic results across hematology, chemistry, and coagulation testing.
What is the difference between EDTA and heparin tubes?
EDTA tubes are used for hematology testing, such as complete blood count (CBC) and blood smear analysis. EDTA acts as an anticoagulant by chelating calcium ions, preserving blood cell morphology. Heparin tubes, on the other hand, are used for plasma chemistry testing and emergency biochemistry analysis, as heparin inhibits thrombin activity and prevents blood clot formation without significantly affecting plasma components.
Which tube is used for glucose testing?
Fluoride tubes are used for glucose testing, typically for blood glucose and lactate analysis. They contain sodium fluoride, which inhibits glycolysis by blocking enzyme activity, preventing red blood cells from consuming glucose after collection. This ensures accurate measurement of blood glucose levels in clinical diagnostics, especially in diabetes screening and monitoring.
What is a serum separator tube?
It is a blood collection tube used for serum separation in clinical chemistry testing. It contains a clot activator and a gel that, after centrifugation, forms a stable barrier between serum and blood cells. This ensures clean serum samples for biochemical analysis such as liver function, kidney function, and electrolyte testing.
Which tube is used for coagulation tests?
Citrate tubes are used for coagulation testing, including PT and APTT assays. They contain sodium citrate, which binds calcium ions and prevents blood from clotting during collection, ensuring accurate measurement of coagulation function in clinical laboratories.
