Double-Ended Vacuum Blood Collection Needle (100ct) 21G 0.8x38mm

Title: 100 x Double-Ended Vacuum Blood Collection Needles (21G, 0.8x38mm)

These double-ended needles ensure a closed system for vacuum blood collection, preventing contamination. One end pierces the patient’s vein, while the other, sealed with a rubber stopper, punctures the vacuum tube’s septum, allowing blood to flow directly into the tube without external contact. This sterile, efficient process minimizes the risk of infection and ensures sample integrity. Ideal for clinical and laboratory settings. 21G, 0.8x38mm. Pack of 100.
