Medical-Grade Porous Stainless Steel Tube

Precision Filtration & Flow Control in Life-Critical Medical Applications

Our medical-grade porous stainless steel tubes are designed for strict hygiene and biocompatibility requirements in modern medical applications. Engineered through advanced metal sintering technology, they ensure controlled porosity, uniform structure, and excellent corrosion resistance, ideal for blood filtration, gas diffusion, drug delivery, and implantable systems.

Key Features for Medical Use

✅ Biocompatible Materials
Manufactured from 316L medical-grade stainless steel, ensuring non-toxicity, non-reactivity, and body fluid compatibility.

✅ High Filtration Precision
Available in pore sizes from 0.2μm to 20μm, suitable for microfiltration, aerosol treatment, and precise flow restriction.

✅ Sterilizable & Reusable
Withstands autoclaving, ethylene oxide (EtO), and gamma radiation without loss of structure or integrity.

✅ Non-Shedding & Particle-Free
100% sintered metal structure – no fiber shedding or contamination risk during medical procedures.

✅ Excellent Corrosion Resistance
Resistant to saline, bodily fluids, cleaning agents, and medical-grade disinfectants.


Common Applications in the Medical Field

  • Respiratory Devices
    Micro-porous tubes for humidified oxygen delivery, aerosol filtration, and ventilator diffusers.

  • Blood Filtration & Dialysis Equipment
    Stable under flow pressure with high surface area and precise pore control.

  • Catheters & Endoscopic Instruments
    Used as flow restrictors, diffusers, or structural cores in minimally invasive tools.

  • Implantable Medical Devices (non-active)
    For fluid exchange, medication diffusion, or tissue scaffolding support.

  • Pharmaceutical Processing Equipment
    Utilized in sterile filtration, powder containment, and micro-dosing nozzles.
