Plain Serum Blood Collection Tube 5ml Red Cap

Description

1. Product Overview

The Plain Serum Blood Collection Tube (5ml, Red Cap) is a precision-engineered in-vitro diagnostic device designed for the collection, transport, and centrifugation of whole blood to obtain high-quality serum specimens. Its primary industrial use lies in clinical chemistry, immunology, serology, and infectious disease testing across hospital laboratories, reference labs, and blood collection centers. The key value proposition is its ability to deliver clot activator-free serum separation with zero interference to downstream assays, ensuring analytical accuracy and regulatory compliance. Strategically, this product is critical to global diagnostics as it underpins reliable biomarker detection, therapeutic drug monitoring, and population health screening—demand for which has grown 12% annually post-pandemic.

2. Key Specifications & Technical Characteristics

• Tube Material: Medical-grade PET (polyethylene terephthalate) or borosilicate glass – non-leaching, break-resistant (ISO 6710:2017 compliant)

• Closure System: Red HDPE safety cap with threaded design and integrated silicone O-ring – provides airtight seal, leak-proof during centrifugation (RCF up to 1300g)

• Additive: None – plain (non-additive) for endogenous coagulation; silica-coated interior wall to accelerate clotting without interfering with serum chemistry

• Volume Nominal: 5mL ±10% (draw accuracy per ISO 6710)

• Vacuum Pressure: Pre-set at -0.5 to -0.7 bar (ensures 95-105% fill accuracy)

• Physical Form: Cylindrical tube, clear wall; red cap color-coded per CLSI/NCCLS standard

• Sterility: Gamma-irradiated (SAL 10⁻⁶) or EO – sterile interior and exterior

• Shelf Life: 18 months from date of manufacture (when stored at 4°C–25°C, humidity ≤65%)

• Packaging Options:

  • Bulk: 1000 tubes/bag (no rack)

  • Racked: 100 tubes/rack, 10 racks/case (1000 tubes/case)

  • Sterile sleeve: 50 tubes/pouch, 20 pouches/carton

3. Core Industrial Applications

• Primary Industries: Clinical diagnostics, hospital central labs, reference laboratories, veterinary diagnostics, blood banks (for donor screening), pharmaceutical clinical trial labs.

• Operational Use Cases:

  • Routine chemistry (glucose, liver enzymes, lipids, creatinine)

  • Serology (HIV, HBV, HCV, syphilis, SARS-CoV-2 antibody testing)

  • Endocrinology (TSH, T3, T4, cortisol, insulin)

  • Therapeutic drug monitoring (digoxin, lithium, vancomycin)

• Why this product outperforms alternatives:

  • No gel separator eliminates risk of gel interference in LC-MS/MS and immunoassays – critical for trace analyte detection.

  • Faster clot time (30–60 minutes at 22°C) vs. glass plain tubes (60–90 minutes) due to silica coating, increasing lab throughput by 25%.

  • Break-resistant PET reduces needle-stick injuries and broken glass hazards in high-volume settings (10,000+ tubes/day).

  • Cost advantage: Lower per-unit cost vs. serum separator tubes (SST) – ideal for labs running assays unaffected by fibrin clots.

4. Competitive Advantages

• Quality Consistency: Batch-to-batch coefficient of variation (CV) <3% for vacuum pressure and draw volume – validated via ISO 13485:2016 certified manufacturing.

• Supply Reliability: Dual-source raw material (PET resin from Eastman & Indorama) with 18-month rolling forecast commitment. Stocked in 3 regional hubs (NA, EU, APAC) – 98% on-time delivery KPI.

• Logistics Capability: Ambient temperature shipping (2°C–30°C) – no cold chain required. Fully palletized, trackable via RFID batch coding.

• Price Competitiveness: 15–20% lower total landed cost vs. leading EU brands (BD, Sarstedt) – achieved via automated high-speed assembly (500 tubes/min).

• Sustainability: 100% recyclable PET (class 1). Red caps made from 30% post-industrial recycled HDPE. Packaging uses FSC-certified cardboard.

• Technical Support: Free validation samples (50 tubes), lot-specific sterility/endotoxin certificates, and 24/7 access to application specialist for protocol troubleshooting.
