Covidien Monoject Blood Collection Tube 2 ml 10.25 mm x 50 mm 2 Packs of 100 Tubes Each

Monoject™ 2 mL Red Stopper Blood Collection Tubes (8881301116) – Lot of 200 Tubes

The Monoject™ 8881301116 standard blood collection tubes (now manufactured under the Cardinal Health portfolio, formerly Covidien) are elite vacuum-sealed laboratory vessels optimized for routine serum chemistry, serology testing, and clinical sample processing. Measuring 10.25 mm x 50 mm with a 2 mL draw volume, these high-purity glass tubes feature a no-additive, silicone-coated interior that promotes clean clotting without interfering with serum components. Outfitted with a specialized glycerine-coated conventional red stopper, this lot of 200 tubes ensures stable vacuum retention and leak-free centrifugation transitions.

Technical Performance & Design

• No-Additive Pure Serum Chemistry: Formulated completely free of anticoagulants or clot activators, allowing the natural coagulation cascade to proceed natively for clear, unaltered serum extractions.
• Silicone-Coated Interior Walls: Inner glass boundaries are treated with a water-soluble micro-layer of silicone, reducing red blood cell adhesion to the walls, accelerating clot retraction, and minimizing hemolysis risks during centrifuge spins.
• Glycerine-Coated Rubber Closure: Equipped with a tight-fitting red conventional stopper treated with a glycerine film lubrication layer. This layer ensures smooth manual or automated decapping while maintaining a hermetic vacuum seal over long shelf lives.
• Premium Glass Geometry: Fabricated from heavy-walled, high-clarity glass capable of handling intensive relative centrifugal forces (RCF) inside standard swing-bucket or fixed-angle clinical rotors.

Key Benefits & Applications

• Routine Serum Chemistry Analysis: Serves as an ideal raw substrate container for blood panels requiring clear serum, including metabolic profiles, liver function panels, lipid tracking, and drug monitoring assays.
• Serology and Immunology Processing: The absence of anticoagulant chemicals blocks interference during antibody screenings, antigen test validations, and blood bank cross-matching procedures.
• Reliable Vacuum Draw Matrix: Precision-calibrated internal negative pressure ensures an exact 2 mL fluid draw upon venipuncture needle connection, preventing overfill variables or sample dilution shifts.
• Aseptic Transfer Maintenance: The sterile interior environment prevents the introduction of external microbial contaminants, preserving specimen integrity during transport to central testing facilities.
