The Gel and Clot Activator Tubes 4ml Yellow (Pack of 100) supplied by IBEX SCIENCES are medical-grade, sterile specimen containers engineered for high-efficiency serum separation in clinical diagnostic laboratories. [1, 2]
Identified globally by their distinct yellow color-coded caps, these Serum Separator Tubes (SST) are engineered to yield premium-quality serum specimens for automated testing. [1, 2, 3, 4, 5]
Key Product Specifications
-
- Dual Additive System:
-
- Clot Activator: The interior walls are uniformly spray-coated with micronized silica or inert particle coagulants. These accelerate the natural coagulation cascade, shortening the required blood clotting time to roughly 30 minutes.
- Separation Gel: Features a highly stable, inert polymer barrier gel positioned at the bottom of the tube. During centrifugation, this gel physically migrates to form an impermeable layer between the separated serum and the dense cellular blood clot. [1, 2, 3, 4, 5]
-
- Draw Volume: Precision engineered to sustain a reliable 4ml capacity draw, balancing optimal sample sizes with required chemical ratios. [1, 2, 3]
- Packaging Configuration: Packaged as a standard laboratory brick containing 100 pieces per box. [1, 2]
- Material Integrity: Molded from premium, shatter-resistant transparent PET plastic or medical-grade glass, paired with a leak-proof rubber stopper system. [1, 3]
- Dual Additive System:
Primary Clinical Applications
These tubes are ideally designed for general serum determinations, helping medical labs bypass cell contamination and preserve intact serum parameters for: [1, 2]
-
- Routine Biochemistry Panels: Liver Function Tests (LFT), Kidney Function Tests (KFT), Basic and Comprehensive Metabolic Panels (BMP/CMP), and Lipid Profiles. [1, 2]
- Immunology & Serology: Hormone profiles, therapeutic drug monitoring, and infectious disease screenings (e.g., Hepatitis, HIV, Syphilis). [1, 2, 3]
- Blood Bank Operations: Routine cross-matching and donor blood screening. [1]
Proper Handling Protocol
To guarantee an accurate laboratory readout, the collector must gently invert the tube 5 to 6 times immediately following the blood draw. This completely mixes the blood with the spray-dried clot activator. The tube should then rest upright for 30 minutes to clot fully before being loaded into a centrifuge. Intense shaking is strictly prohibited, as it can cause specimen hemolysis (rupturing of red blood cells). [1, 2, 3, 4, 5]
