Brief: Our team walks you through how the 304 Stainless Steel Capillary Thread Side Hole Puncture Needle performs in common scenarios. In this video, you'll see a detailed demonstration of its precision side-port machining and threaded connection process, learn how it ensures leak-proof performance in high-pressure systems, and discover its applications in chromatography and industrial instrumentation.
Related Product Features:
  • Precision-engineered from 304 stainless steel for durability and corrosion resistance in demanding applications.
  • Features a fine-bore capillary tube for handling small fluid volumes with high accuracy.
  • Includes precision-machined side ports for alternative fluid egress or sampling away from sediment.
  • Equipped with threaded sections for robust mechanical connections and vibration-resistant sealing.
  • Available in various tip configurations including lancet, pencil point, or blunt tips for specific uses.
  • Designed for high-pressure systems with pressure ratings that can exceed 5000 psi.
  • Undergoes rigorous testing including 100% dimensional inspection and helium leak checks.
  • Electropolished and passivated surface finish ensures smooth flow and prevents contamination.
FAQs:
  • What are the primary applications for this puncture needle?
    It is ideal for high-pressure chromatography (HPLC/GC), chemical process instrumentation for sealed sampling, fluid power systems, specialized medical device manufacturing equipment, and R&D for custom fluidic interfaces requiring secure connections.
  • How is the leak integrity of the needle ensured?
    Each needle undergoes 100% rigorous testing, including helium leak detection or hydrostatic pressure tests, to verify that both the side ports and threaded connections provide a secure, leak-proof seal under specified pressure conditions.
  • What thread types and tip configurations are available?
    Common thread types include 10-32 UNF, 1/4-28 UNF, M6x1.0, and 1/8" NPT, with custom options available. Tip configurations can be lancet (sharp) for piercing, pencil point (non-coring), or blunt for fluid transfer solely through the side port.
