Designed for clinical pathology laboratories, hospital wards, and blood banks. Fully compliant with international color codes, sterile vacuum standards, and automated laboratory analyzers.
Tripotassium EDTA spray for routine haematology, CBC, and cell morphological examination. Binds free calcium ions to inhibit clotting.
Micro-spray coated Dipotassium EDTA, the globally recommended international standard for automated hematology analyzers, HbA1c, and PCR.
Silicone-coated interior walls without anticoagulant. Allows natural physiological clotting for pristine serum extraction in clinical serology.
Coated with micronized silica particles that accelerate coagulation within 20–30 mins. Yields high volumes of fibrin-free serum for biochemistry.
Calibrated 1:9 ratio solution for precise Prothrombin Time (PT/INR), APTT, and clotting factor assays recommended by international laboratory standards.
Dedicated 1:4 dilution ratio specifically calibrated for Westergren erythrocyte sedimentation rate (ESR) measurement in clinical pathology.
Potent glycolysis inhibitor preventing glucose breakdown for up to 48 hours. Essential for fasting blood glucose and tolerance tests (OGTT).
Spray-coated lithium heparin prevents thrombin formation for rapid plasma preparation in emergency clinical chemistry, electrolytes, and cardiac panels.
