Centrifuge Tube (50mL CONICAL PP)

1. Product Overview
This product is a 50mL polypropylene (PP) conical-bottom centrifuge tube, engineered for high-performance sample preparation, cell culture processing, and biopharmaceutical centrifugation. Its primary industrial use lies in clinical diagnostics, research laboratories, and commercial bioproduction facilities. The key value proposition is its combination of mechanical strength (up to 12,000 RCF), chemical resistance, and leak-proof integrity — reducing sample loss and equipment contamination risk. Strategically, this tube is indispensable for global supply chains requiring consumables that balance precision engineering with cost efficiency at scale.

2. Key Specifications & Technical Characteristics

• Material Composition: Virgin, medical-grade polypropylene (PP), free from heavy metals, endotoxins, and RNase/DNase.

• Purity/Grade: DNase/RNase-free, pyrogen-free (endotoxin <0.1 EU/mL), non-cytotoxic (ISO 10993-5 compliant).

• Physical Characteristics:

  • Conical bottom (55° angle) for maximum pellet recovery.

  • Graduations: Molded black or white刻度 (5–50mL, 2mL increments).

  • Closure: Flat-top or plug-seal screw cap (ethylene-vinyl acetate liner available).

  • Color: Natural translucent or amber (UV protection option).

• Thermal Resistance: -80°C to +120°C (freezable, autoclavable at 121°C).

• Centrifugal Tolerance: Up to 12,000 × g (RCF).

• Packaging Options: Bulk bag (25 pcs/bag, 500 pcs/case); sterile gamma-irradiated or non-sterile; racked or bulk.

• Shelf Life: 5 years from date of manufacture (when stored at 15–25°C, dry).

3. Core Industrial Applications

• Primary Industries: Biopharmaceutical R&D, clinical diagnostic labs, academic research, agricultural testing, and industrial chemical processing.

• Operational Use Cases:

  • Cell pelleting & re-suspension in monoclonal antibody production.

  • Density gradient centrifugation (e.g., Ficoll) for peripheral blood mononuclear cell isolation.

  • Large-volume sample storage and transport for forensic or environmental testing.

• Performance Advantages vs. Alternatives:

  • Outperforms polystyrene tubes in chemical resistance (tolerates acetone, ethanol, weak acids).

  • Superior mechanical strength compared to recycled-PP tubes — fewer cracks under high g-force.

  • Conical geometry reduces dead volume by ~30% vs. round-bottom tubes, cutting reagent waste.

  • Cost-per-unit lower than glass while eliminating breakage risk.

4. Competitive Advantages

• Quality Consistency: Lot-to-lot dimensional tolerance <±0.5% (ISO 9001:2025 & ISO 13485 certified). Each batch 100% leak-tested.

• Supply Reliability: Dual-sourced resin inventory with three redundant manufacturing lines in Asia and Europe; 98% on-time delivery guarantee.

• Logistics Capability: Ready-to-ship from regional hubs (Rotterdam, Singapore, Houston) — air and sea options.

• Price Competitiveness: Tiered pricing for annual volumes >1M units; 15–20% below top-tier premium brands at equivalent spec.

• Sustainability: 100% recyclable PP (#5 plastic); bulk packaging reduces plastic waste by 40% vs. boxed alternatives.

• Technical Support: Full documentation pack (COA, MSDS, sterility validation, RCF curves) available via digital portal; application engineering support for validation.

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): 20,000 units (mix of sterile/non-sterile accepted) or 40 master cartons.

• BULK 20MT Loading Capacity: Approx. 2.2 million units per 20-foot dry container (based on 500 pcs/case, 40 cases/pallet, 20 pallets per container — without racking).

• Lead Time: 14 days for stock items; 30 days for customized printing (logo, lot traceability).

• Payment Terms: Letter of Credit (L/C at sight) or net 30 for qualified corporate accounts after credit review.
