Medical Grade 304 316L Needles Precise Stainless Steel Capillary Tubing

Medical Grade 304 316L Needles , Precise Stainless Steel Capillary Tubing for Medical Device
 
 
Stainless steel capillary tube needle tubing is a type of specialized tubing used in various medical applications, such as hypodermic needles, biopsy devices, and catheters. Here are some key points to know:

1. Material:

   • Stainless steel is the primary material used for capillary needle tubing due to its excellent properties, including corrosion resistance, durability, and biocompatibility.
   • Common stainless steel grades used for capillary needle tubing include 304, 316, and 316L.
   • These grades offer high resistance to corrosion, making them suitable for medical applications that involve contact with bodily fluids or harsh environments.

2. Size and Dimensions:

   • Capillary needle tubing typically has small outer diameters and thin walls to accommodate its numerous medical applications.
   • The outer diameter (OD) can range from a fraction of a millimeter (e.g., 0.2 mm) to several millimeters, depending on the specific application.
   • The inner diameter (ID) of the tubing is smaller, enabling the flow of fluids or insertion of medical instruments.

3. Precision and Tolerance:

   • Capillary needle tubing requires high precision and tight tolerances to meet the stringent requirements of medical devices.
   • The production of capillary needle tubing involves advanced manufacturing techniques, such as cold drawing, to achieve consistent dimensions and excellent surface finish.

4. Biocompatibility and Sterilization:

   • Stainless steel capillary needle tubing is known for its excellent biocompatibility, meaning it is well-tolerated by the human body and does not cause adverse reactions.
   • The tubing can be sterilized through various methods, such as autoclaving, ethylene oxide (ETO) sterilization, or gamma irradiation, ensuring its suitability for medical use.
