We’re proud to offer 316 stainless steel capillary tubes, a go-to choice for medical catheter applications. These tubes are a game-changer in the medical field, and here’s why we think they’re the real deal.

Our 316 stainless steel capillary tubes are made from a high-grade alloy with molybdenum and low carbon content, giving them top-notch corrosion resistance. This is a big deal for catheters, which are constantly exposed to bodily fluids and harsh sterilization processes. They don’t rust or degrade, even in chloride-heavy environments, which means they stay reliable for the long haul. Whether it’s for diagnostic or therapeutic devices, these tubes hold up where others might fail.

Biocompatibility is another area where our tubes shine. The chromium oxide layer on the surface acts like a shield, preventing metal ions from leaching into tissues and reducing the risk of reactions like inflammation. This makes them perfect for catheters that need to stay in the body for extended periods, ensuring patient safety and comfort. Plus, their smooth surface cuts down on friction, making procedures less invasive and more comfortable for patients.

Precision is key in catheter applications, and our tubes deliver. With outer diameters as small as 0.3 mm and wall thicknesses down to 0.1 mm, they’re designed for tight spaces and precise fluid transfer. Think drug delivery systems or insulin pens—these tubes ensure accurate dosing every time. Their high strength-to-weight ratio means they can be super thin yet still handle the pressures of complex medical procedures without breaking a sweat.

We also love how versatile these tubes are. They’re not just for catheters; you’ll find them in high-performance liquid chromatography (HPLC), endoscopes, and even semiconductor manufacturing. Their ability to withstand high temperatures and chemicals makes them a favorite across industries. And while the upfront cost might be a bit higher than alternatives like polymer or glass, their durability and low maintenance make them a cost-effective choice over time.

Keeping these tubes in top shape is straightforward. We clean, polish, and passivate them to ensure they’re ready for immediate use, free of impurities that could mess with performance. Customization is another perk—we can tweak sizes, wall thicknesses, or finishes to fit your exact needs. Whether you’re designing cutting-edge medical devices or upgrading existing ones, our 316 stainless steel capillary tubes are built to perform.

The medical tubing market is growing fast, with a projected value of USD 18.41 billion by 2030, driven by demand for minimally invasive procedures and advanced materials like ours. As healthcare leans more on precision and biocompatibility, our tubes are positioned to meet those needs head-on. From catheters to diagnostic tools, we’re committed to delivering quality that supports better patient outcomes and pushes medical innovation forward.
