ASTM A269 SUS304 Medical Grade Capillary Tubes, Corrosion Resistant,Precise for Hypodermic Needles, Medical Devices

ASTM A269 SUS304 medical capillary tubing is a precision micro-tube manufactured according to ASTM A269 standards, made of SUS304 stainless steel, and specifically designed for medical applications.

304 stainless steel is widely recognized for its good biocompatibility. Thanks to its excellent corrosion resistance and biocompatibility, capillary tubes play a crucial role in the medical field.

Medical Needle Application Selection Notes: TP304 is commonly selected for general medical needle applications requiring good strength, ductility, and corrosion resistance.

TP304L offers enhanced weldability due to its lower carbon content, making it ideal for welded needle assemblies where post-weld annealing is not performed.

304/304L Dual Certified tubing is also available, meeting both composition requirements, providing maximum flexibility for medical device manufacturing.

Let me know if you need additional data such as surface finish requirements (BA/EP) or dimensional tolerances for medical capillary tube applications.

Applications:

Forceps and irrigation/suction tubes for laparoscopic and arthroscopic endoscopes, or as precision components of catheters and guidewires.

Inner cannulas for high-end injection needles, puncture needles, and insulin pump tubing, ensuring accurate.

Dental and Surgical Tools: Water/air supply tubing for dental handpieces, or as the rigid component of liposuction cannulas and surgical irrigation tubes.

In Vitro Diagnostic Equipment: Inside blood analyzers, biochemical analyzers, and other equipment, responsible for the precise and stable delivery of minute amounts of reagents or samples.

Medical Device Sensors: Protective sheaths for temperature probes and pressure sensors, isolating interference and ensuring accurate signal transmission.
