Stainless steel capillary tubing: Due to its high strength, corrosion resistance, and cleanability, it is used in medical devices such as catheters, precision instruments, and sensors.
The term "needle tubing" usually refers to the needle portion of a syringe, with the tip precisely machined to a sharp bevel for easy penetration into the skin or seals.
Needle tubing adheres to strict medical standards and specifications, particularly the G (Gauge) gauge. The larger the gauge, the thinner the tubing. For example, 21-gauge tubing is commonly used for blood draws, while 29-gauge or 31-gauge tubing is commonly used for insulin injections.
Almost exclusively, these tubings are manufactured from high-quality medical-grade stainless steel to ensure sufficient rigidity, sharpness, and safety.

Reasons for choosing 316L stainless steel as the core material for needle tubing:
Primarily due to its excellent biological properties and reliability. Key to this is the addition of molybdenum, which significantly enhances the material's resistance to pitting and crevice corrosion in chloride-containing bodily fluids, providing top-tier corrosion resistance exceeding that of 304 stainless steel.
Being able to withstand the rigorous demands of long-term or short-term contact with human tissue or blood, it has become a recognized standard material in the medical industry for devices such as hypodermic needles, biopsy needles, and various interventional catheters.
Hypodermic Needles: Used for subcutaneous, intramuscular, or intravenous injection of medications or for drawing blood.
Biopsy Needles: Used for puncturing and extracting tissue samples (such as liver and breast) for pathological analysis.
Anesthetic Needles and Puncture Needles: Used for surgical anesthesia or puncture and drainage of various body cavities and cysts.
Interventional Devices and Implantable Devices
Catheters: Serves as puncture guides for intravascular catheters or as channels for delivering contrast agents and medications.
Interventional Guidewires: Some fine interventional guidewires are constructed with stainless steel needles.
Serves as working components of minimally invasive surgical instruments such as laparoscopes and endoscopes.
