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 HeparinPharmaceutical-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 DesignPre-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.
