Covidien Monoject Blood Collection Tube 2 ml 10.25 mm x 50 mm 5 Packs of 100 Tubes Each

Monoject™ Venous Blood Collection Tubes, K3 EDTA Hematology, 2 mL (8881311149) – 500 Pack

The Monoject™ Venous Blood Collection Tube (8881311149) (manufactured under the Covidien/Cardinal Health medical portfolio) is a clinical-grade vacuum sampling consumable engineered for precise diagnostic fluid collection, cell morphology preservation, and routine whole-blood hematology procedures. Featuring a 2 mL nominal draw capacity with a 10.25 mm x 50 mm dimensional profile, each clear borosilicate glass tube contains a precise **0.04 mL liquid formulation of 7.5% Tri-potassium Ethylenediaminetetraacetic Acid ($K_3$ EDTA)** anticoagulant. This unit is presented here as a facility layout of 5 packs containing 100 tubes each (500 tubes total), providing specialized small-volume sampling stability for phlebotomy bays, diagnostic lines, and animal research lab infrastructures.

Technical Performance & Sample Architecture

• Liquid $K_3$ EDTA Anticoagulation: Pre-loaded with 0.04 mL of a 7.5% liquid $K_3$ EDTA solution. This specific chemistry rapidly chelates cellular calcium ions, halting the coagulation cascade and safeguarding fragile leukocyte, erythrocyte, and platelet morphology for subsequent analytical counting.
• Non-Silicone Coated Interior Glass Matrix: Fabricated with an un-lubricated interior wall line to prevent non-specific plasticizer leaching or chemical interference. This raw surface layout ensures maximum compatibility with demanding whole-blood kinetic readouts and sensitive clinical assays.
• Glycerine-Coated Lavender Rubber Stopper: Outfitted with a conventional, high-visibility lavender rubber closure treated with an ultra-thin layer of medical-grade glycerine. This smooth finish minimizes friction during physical needle puncture and structural tube capping while serving as a global color indicator for hematology panels.
• Sterile Tube Interior Infrastructure: The internal vacuum and interior tube surfaces are sterilized under strict automated facility loops, completely eliminating external particulate or bacterial contamination risks prior to primary venipuncture.

Key Benefits & Applications

• Routine Complete Blood Count (CBC) Panels: The industry-standard vessel for running erythrocyte sedimentation rates, automated hematology cell counts, and blood film morphological profiling.
• Small-Volume and Pediatric-Equivalent Assays: The compact 2 mL draw volume profile is exceptionally well-suited for specialized sampling matrices, lower-volume geriatric collections, and diagnostic veterinary lines.
• Flow Cytometry and Cellular Indexing: Provides an unaltered, anticoagulant-stabilized whole blood pool optimized for immunophenotyping, cell-surface marker staining, and ambient leukocyte sorting.
• **ANSI-Compliant Rack Integration:** The 10.25 mm tube diameter slots flawlessly into routine automated analyzer tracks, clinical centrifuges, and multi-position benchtop blood mixers, eliminating transfer steps.
