Brief: Learn how this solution can streamline typical workflows and improve reliability. In this video, we demonstrate the precision manufacturing process of a 316L stainless steel medical capillary tube with grinding, marking, sandblasting, and variable diameter features. You'll see how each processing step - from material verification to final inspection - creates a high-performance component ready for critical medical and laboratory applications.
Related Product Features:
  • Precision-ground bevel tip for sharp penetration and controlled fluid egress in medical applications.
  • Permanent laser marking ensures clear identification and traceability throughout the product lifecycle.
  • Uniform sandblasting creates a cleanable matte finish while enhancing grip and surface quality.
  • Hermetic end capping provides reliable sealing for pressurized fluid systems and implantable devices.
  • Controlled diameter reduction allows for precise fitting integration and flow control customization.
  • Medical-grade 316L stainless steel construction with full material certification and traceability.
  • Comprehensive surface treatment including passivation for maximum corrosion resistance.
  • 100% dimensional inspection and seal integrity testing ensures consistent quality and performance.
FAQs:
  • What applications are these medical capillary tubes suitable for?
    These precision tubes are designed for critical medical and laboratory applications including implantable drug delivery systems, high-pressure chromatography (HPLC/UHPLC), analytical sensor probes, micro-surgical tools, and laboratory fluidic manifolds where reliable performance and traceability are essential.
  • How is the end sealing integrity verified during manufacturing?
    All sealed ends undergo 100% integrity testing using helium leak detection or pressure decay testing methods. For welded seals, we achieve leak rates better than 1 x 10⁻⁹ atm*cc/sec, ensuring hermetic sealing for pressurized applications.
  • What quality documentation is provided with these components?
    Each shipment includes comprehensive documentation including Certificate of Conformance, Dimensional Report, Mill Test Report with full material traceability, Passivation Report, and Leak Test Certificate where applicable, supporting compliance with medical device regulations.
  • Can the internal surface finish be customized for specific fluid applications?
    Yes, the internal surfaces can be electropolished to achieve surface roughness (Ra) below 0.4 µm, providing optimal flow characteristics and minimizing particle retention for sensitive fluid handling applications.
