Title: 21G Double-Ended Vacuum Blood Collection Needle

Description:

This sterile, double-ended 21G vacuum blood collection needle is designed for use with a reusable needle holder. One end features a silicone-coated bevel for smooth, painless venipuncture. The other end, sealed with a soft rubber septum, pierces the rubber stopper of vacuum blood collection tubes. This septum maintains system closure, preventing contamination and ensuring sample integrity during multi-tube draws. The needle's protective sheath features a perforated label for easy access and tamper-evident packaging. Its extended design protects the needle tip from damage. Available in 25mm and 38mm lengths and various gauges (G18, G20, G21, G22, G23) to comply with ISO 6710 color-coding standards. Key features include: stainless steel construction; complete sterility (indicated on packaging); color-coded cannula (ISO 6710); silicone coating (internal and external); flexible rubber septum preventing backflow; double bevel; triple laser-sharpened point; and a cannula thread for secure attachment to the needle holder.
