Product Name	Veterinary Clot Activator Serum Tube
Product Image
Product Overview	The Veterinary Clot Activator Serum Tube is designed for venous blood collection and serum preparation in cattle, pigs, goat-farming-equipment/" target="_blank" class="keylink">sheep, goats, horses and other animals. The tube contains a clot activator that promotes controlled coagulation, allowing serum to be separated after the blood has fully clotted and the sample has been centrifuged. A pre-set internal vacuum automatically draws the intended blood volume when the tube is connected to a compatible veterinary blood collection needle and holder. The closed collection process helps simplify sample handling and reduces unnecessary blood transfer between containers. The tube is suitable for veterinary clinical chemistry, serology, disease screening and routine herd health programs in commercial livestock farms, veterinary hospitals, diagnostic laboratories and breeding operations.
Key Features	Clot activator supports reliable serum preparation after venous blood collection. Pre-set vacuum provides controlled sample draw volume. Red closure provides rapid identification of serum clot activator tubes. Suitable for veterinary chemistry, serology and general diagnostic testing. Closed collection format reduces manual transfer of blood specimens. Compatible with suitable vacuum blood collection needles and holders. Available in multiple draw volumes and tube dimensions. Sterile configurations are available for standardized blood collection procedures. Suitable for cattle, pigs, sheep, goats, horses and other veterinary patients. Designed for single-use veterinary and laboratory workflows.
Structural Components	Vacuum Tube Body: Transparent collection tube designed to maintain the specified internal vacuum. Clot Activator: Applied to the interior of the tube to promote controlled blood coagulation. Red Safety Closure: Provides secure sealing and clear tube-type identification. Rubber Stopper: Allows penetration by the collection needle while maintaining a closed system. Identification Label: Provides space for animal ID, sample number, date and other laboratory information. Pre-Set Vacuum: Draws the intended amount of blood into the tube during collection.
Working Principle	During blood collection, a compatible double-ended needle enters the vein and then penetrates the tube stopper inside the holder. The pressure difference between the evacuated tube and the atmosphere causes blood to flow automatically into the tube until the intended filling volume is reached. The clot activator inside the tube promotes coagulation. After collection, the sample is gently mixed according to the applicable instructions and then allowed to clot completely before centrifugation. After centrifugation, serum is separated from the cellular fraction and can be used for appropriate veterinary diagnostic testing. Serum clot activator tubes should be allowed sufficient clotting time before centrifugation to reduce the risk of residual fibrin.

Use & Handling	Select the appropriate tube capacity and blood collection needle according to the animal species, sample volume and laboratory test requirements. Inspect the tube before collection and do not use damaged tubes or tubes with compromised vacuum integrity. Perform venipuncture using appropriate animal restraint and aseptic veterinary technique. Insert the tube into the compatible holder and allow the vacuum to draw blood until flow stops. After collection, gently invert the tube as specified by the applicable product instructions to distribute the clot activator. Do not shake the sample vigorously. Allow the blood to clot completely before centrifugation. Reference manufacturer instructions for serum tubes specify a minimum clotting period of approximately 30 minutes under normal conditions. Samples with delayed coagulation may require additional time. Process, store and transport serum according to the requirements of the intended diagnostic test. Used collection tubes and contaminated materials should be discarded in accordance with local veterinary biohazard regulations.
Product FAQ	What is a clot activator serum tube used for? It is used to collect venous blood and promote clot formation so that serum can be separated for veterinary chemistry, serology and other diagnostic tests. Does the tube contain an anticoagulant? No. A serum clot activator tube is designed to promote coagulation rather than prevent it. How long should the sample clot before centrifugation? The applicable manufacturer instructions should always be followed. Reference instructions for VACUETTE serum tubes specify complete clotting and a minimum period of approximately 30 minutes before centrifugation. Can the tube be used for cattle and pigs? Yes. Serum clot activator tubes can be used for cattle, pigs, sheep, goats, horses and other animals when the appropriate collection volume and veterinary procedure are selected. Why is the closure red? Red closures are commonly used to help identify serum collection tubes containing clot activator or no anticoagulant, depending on the specific tube system. Can different capacities be supplied? Yes. Multiple tube capacities and dimensions can be supplied according to animal species, laboratory requirements and project specifications.
