2. Process Flow: Serum Separator Tube Manufacturing

End-to-End Manufacturing Workflow

Raw Materials Selection → Tube Forming (Injection molding: PET/PP) → Clot Activator Dosing (Automated micro-dosing, e.g. silica, 10-20 mg) → Gel Dispensing (Precision layering of thixotropic polymer gel) → Cap Sealing (Color-coded, airtight) → Sterilization (Gamma/ETO, ISO 11137) → Printing & Labeling (Barcoding per ISO 6710) → Final QA & Automated Batch Release

Each step is digitally verified for particle uniformity, gel homogeneity, and absence of pyrogens, following stringent ISO and FDA procedures. Material traceability is logged electronically for at least 4 years per lot.

Serum Yield Rate: Key Technologies

Serum Separator + Gel tubes recover >95% of total serum from whole blood, compared to <92% in plain tubes.

Batch Defect Rate by Type (per 10,000 units, 2023)

Defect rates are lowest for serum separator (gel) tubes, reducing risk of hemolysis, vacuum leakage, and additive inconsistency.

Market Adoption Trends 2019-2024

Global adoption of clot activator + separation gel gold tubes continues exponential growth, displacing legacy glass.

Key Findings: Gel Separator and Clot Activator tubes consistently surpass traditional clot activator and plain tubes in serum yield, sample integrity, and regulatory compliance—vital for critical results in biochemistry/immunochemistry.
