10G-34G Stainless Steel Welded Capillary Tube For Medical Hypodermic Use ISO9626 SUS304

A Stainless Steel Welded Capillary Tube is a thin-walled, small-diameter tube manufactured by forming a stainless steel strip into a cylindrical shape and then welding the seam along its entire length using a precision process (typically Laser welding). The capillary tube is then cold drawn and annealed to achieve its final dimensions, mechanical properties, and a smooth, flawless interior surface. The Stainless Steel Welded Capillary Tube is manufactured from SUS304 material and complied with ISO9626 standard, which has strict dimensional tolerance and good roughness. Our supplied medical grade capillary tubes are generally cut into 2 meter piece and can also be cut into other fixed length according to clients’ request. Coiled tubes are also available. The regular outer diameter size ranges from 0.18mm to 3.4mm, that is 10 Gauge to 34 Gauge. The minimum diameter can be 0.15mm.

Main Advantages:

• Excellent Corrosion Resistance: SUS304 stainless steel
• High Strength and Ductility: The cold-working and annealing processes give the tube an optimal combination of strength to prevent buckling and ductility for forming sharp, burr-free points.
• Superior Surface Finish: The interior and exterior surfaces are meticulously polished and cleaned to a micro-finish. This prevents fluid adhesion, minimizes friction during insertion, and ensures easy cleaning and sterility.
• Biocompatibility: SUS304 is generally considered biocompatible for many medical applications. For many hypodermic and short-term uses, 304 is perfectly suitable and cost-effective.
• Consistent Dimensional Accuracy: The welded and drawn manufacturing process allows for exceptional control over dimensions, leading to high reliability and performance in automated assembly lines.

Medical Applications:

• Hypodermic Needles: The primary use. For medication administration.
• IV Catheters: Used as the "stylet" or introducer needle that is placed inside a flexible catheter.
• Biopsy Needles: For collecting tissue samples (e.g., core biopsy needles).
• Spinal and Epidural Needles: For anesthesia delivery into the spinal canal.
• Dental Needles: For local anesthesia in dental procedures.
• Lancets: For blood glucose testing.
• Guide Wires: As the core component for steerable guide wires used in minimally invasive surgery.
• Huber Needles: For accessing implanted ports for chemotherapy or long-term drug delivery.

Non-Medical Applications:

The unique properties of this precision tubing make it valuable in other high-tech industries:

• Chromatography: Used as sample injection needles and fluidic paths in High-Performance Liquid Chromatography and Gas Chromatography systems.
• Precision Instrumentation: For pneumatic and hydraulic systems in sensitive equipment.
• Electronics: As shielding sleeves for optical fibers or as structural components in small devices.
• Watchmaking: For intricate mechanical parts and oil channels.
• Automotive Sensors: As protective sheaths for temperature and pressure sensors.
