Gel Clot Activator Tubes vs. Serum Clot Activator Tubes

Uses and Characteristics

Serum Clot Activator Tubes

• Main Usage: Primarily used for the collection of blood samples, especially those that require the separation of serum for biochemical, immunological, and other testing purposes.

• Characteristics: The blood collection tube usually contains a clot activator, which promotes blood clotting, thus facilitating subsequent serum separation. Different brands and products may use different formulations of clot activators to achieve optimal separation results.

• Additional Features: Some serum clot activator tubes may also contain other additives, such as stabilizers and preservatives, to ensure the stability and safety of the sample during collection, transport, and storage.

Gel Clot Activator Tubes

• Main Usage: Similarly used for the collection of blood samples but with a greater focus on the separation and preservation of the sample. Gel clot activator tubes can form a stable gel barrier during centrifugation, effectively separating the serum from cellular components.

• Characteristics: The tube contains special gel materials that can form a barrier during centrifugation, preventing the mixing of serum with cellular components, thereby providing high-quality serum samples. Additionally, gel clot activator tubes usually have good thermal stability and durability, making them suitable for long-distance transport and long-term storage.

• Additional Features: Besides the basic separation function, some gel clot activator tubes may also have additional special features, such as preventing sample hemolysis and inhibiting microbial growth.

Operation Requirements

Serum Clot Activator Tube

Relatively Simple Operation

Just follow the routine blood collection procedures, without the need for special equipment or techniques.

Gel Clot Activator Tube

Higher Operational Requirements

Strict control over centrifuge speed and time is needed to ensure the formation of the gel barrier and effective serum separation.

Application Scenarios

Serum Clot Activator Tubes

Widely Used in Routine Testing

Such as liver and kidney function, electrolytes, blood sugar, and other biochemical indicators. Due to its simplicity and reliable results, it is also widely used in emergency testing.

Gel Clot Activator Tubes

Suitable for Tests Requiring High-Quality Serum

Such as complex biochemical, immunological, or molecular biology tests. With its good stability and thermal durability, it is also suitable for transporting samples to remote laboratories or for long-term storage.
