High-Quality Stainless Steel Needle For Medical Puncture Use

Product Description

Our 304 stainless steel capillary tubes are precision-engineered for medical experiments and fluid transfer applications. Designed with exceptional biocompatibility and corrosion resistance, these tubes ensure reliable performance in sterile environments such as cell culture, pharmaceutical delivery, and reagent handling. The smooth inner wall minimizes residue adhesion and cross-contamination risks, while customizable dimensions and specialized designs (e.g., double-tube bent dispensing needles) enable versatile use in complex experimental setups. All products comply with ISO 13485 clean production standards and include material certification for traceability.

Product Applications

  • Medical Fluid Transfer: Accurate delivery of cell culture media, pharmaceutical solutions, and reagents.

  • Microsampling & Microfluidic Chips: Precise injection and handling of minimal-volume liquids.

  • Dual-Liquid Dispensing: Simultaneous or alternating delivery of two substances using double-tube bent needles.

  • Surface Treatment & Directional Spraying: Controlled-angle dispensing for specialized spatial applications.

  • High-Pressure Environments: Hydrodynamically stable performance in demanding experimental conditions.
