Engineered for fast, reliable sample processing in emergency and routine clinical settings, our Green-Cap Vacuum Blood Collection Tube with Lithium Heparin is tailored to preserve blood integrity for biochemical and electrolyte testing.
Pre-evacuated to a precise negative pressure, the tube ensures consistent, hassle-free blood draws—eliminating manual aspiration, reducing the risk of sample underfill/overfill, and saving critical time in emergency scenarios. Its core component, pharmaceutical-grade lithium heparin, acts as a potent anticoagulant that binds calcium ions to prevent blood clotting, while preserving the stability of electrolytes (e.g., sodium, potassium, chloride) and biochemical analytes (e.g., glucose, urea, creatinine) for up to 4 hours at room temperature. This ensures accurate, actionable results even for time-sensitive emergency tests.
Crafted from medical-grade PET (lightweight, shatterproof) or borosilicate glass (ideal for trace analyte testing), the tube features a smooth inner wall to minimize hemolysis and cell adhesion—two common causes of test result inaccuracies. The vivid green cap adheres to international lab color-coding standards, enabling instant identification among other blood collection tubes, which is vital for reducing errors in busy emergency departments or high-throughput labs.
Sterile, pyrogen-free, and compatible with standard centrifuges and automated biochemical analyzers, this tube seamlessly integrates into existing lab workflows. Whether used for emergency electrolyte monitoring (e.g., in sepsis or dehydration cases) or routine biochemical profiling, it delivers consistency, speed, and sample integrity—supporting healthcare teams in making timely, informed clinical decisions
Below are its primary functions and applications:
-
Rapid Anticoagulation with Lithium Heparin
Pharmaceutical-grade lithium heparin efficiently binds calcium ions to prevent blood clotting, preserving sample integrity for up to 4 hours at room temperature—critical for maintaining stable electrolyte and biochemical analyte levels.
-
Precision Vacuum Design
Pre-evacuated to a calibrated negative pressure, ensuring consistent blood draw volumes (eliminating underfill/overfill) and streamlining collection in time-sensitive scenarios, such as emergencies.
- Emergency Biochemistry Testing: Ideal for rapid analysis of critical analytes (e.g., glucose, urea, creatinine) in urgent cases like trauma, sepsis, or metabolic crises.
- Electrolyte Monitoring: Preserves stability of sodium, potassium, chloride, and bicarbonate levels—essential for evaluating hydration status, renal function, or acid-base balance.
- Routine Clinical Chemistry: Suitable for non-coagulation-dependent assays in outpatient or inpatient settings, supporting general health screening and disease management.
- Point-of-Care Testing (POCT): Compatible with portable analyzers, enabling on-site electrolyte and biochemical testing in emergency departments, ambulances, or remote clinics.
