GEL&CLOT ACTIVATOR BY ORSIN
Key Features
Highly Efficient Clotting Initiation: Contains high-purity, specific concentrations of clot activators (e.g., Silica, Kaolin, Ellagic Acid, Snake Venom Enzymes, depending on the type) to rapidly and reliably initiate the coagulation cascade, significantly reducing clotting test times.
Excellent Sample Stability: Incorporates an inert gel barrier that forms a stable physical seal after centrifugation, effectively separating serum/plasma from blood cells. This prevents cellular metabolite interference and ensures result accuracy over an extended period.
Pre-filled & Ready-to-Use: Typically supplied in pre-evacuated blood collection tubes, enabling immediate use upon opening. Simplifies workflow, minimizes manual errors, and enhances laboratory efficiency.
High Lot-to-Lot Consistency: Rigorous manufacturing processes and quality control ensure consistent performance across different production lots, guaranteeing reliable and comparable test results.
Broad Compatibility: Suitable for use with a wide range of automated coagulation analyzers and manual testing methods, catering to diverse laboratory requirements.
Basic Parameters
Activator Type: Silica / Kaolin / Ellagic Acid / Snake Venom Enzymes / etc. (Specific type depends on product variant).
Tube Size: Common sizes: 1ml-10ml(Contains micro tubes)
Draw Volume: Requires precise blood draw to the tube's fill line (e.g., 1.8mL, 2.7mL).
Additive Concentration: Precisely optimized concentration of activator for optimal clotting initiation.
Inert Gel: Positioned at the bottom, forms a stable barrier after centrifugation.
Mixing: Tubes must be gently inverted 5-10 times immediately after blood draw to ensure thorough mixing with activator/anticoagulant.
Storage Conditions: Room Temperature (15-30°C). Protect from freezing, excessive heat, and direct sunlight.
Shelf Life: Refer to product outer packaging label (Typically 12-24 months).
Intended Use: Primarily used for venous blood collection, anticoagulation, and clot activation in clinical laboratories for coagulation tests such as Prothrombin Time (PT), Activated Partial Thromboplastin Time (APTT), Thrombin Time (TT), and Fibrinogen (FIB) assays.

Specific Applications
|
Clinical Significance & Precautions
|
|
Biochemistry
|
Liver/kidney function, electrolytes, cardiac enzymes (e.g., lithium, ceruloplasmin), lipid metabolism
|
Basic health screening; avoid hemolysis interference
|
|
Immunoassays

III. Key Supplementary Notes
-
Separation Gel Advantages:
-
Japanese-imported gel with precise density (between serum and blood cells) forms solid barrier post-centrifugation, blocking molecular exchange (>48h serum stability).
-
Temperature-resistant (up to 45°C) and gamma-irradiated for sterilization; resistant to degradation during transport.
-
Limitations for Drug/Hormone Testing:
-
