Double-wall Sodium Citrate Tube

The Double-wall Sodium Citrate Tubes are designed with PET+PP dual-layer construction for enhanced safety and structural integrity. They are pre-filled with either 3.2% (0.109mol/L) or 3.8% (0.129mol/L) buffered sodium citrate, with a precise additive-to-blood ratio of 1:9 — essential for accurate coagulation diagnostics.
