Our 304 stainless steel capillary tubes are precision-engineered for medical experiments and critical 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 (GB/T 4234) for full traceability.
Customization Services
We offer tailored solutions to meet specific experimental needs:
Dimensional Customization: Inner/outer diameter, length, bending angle, and arc.
Port Treatment: Flat, conical, or Luer interface adaptations.
Surface Finish: Electropolishing to Ra ≤0.4μm for ultra-smooth interiors.
Laser Etching: Permanent markings for batch tracking and identification.
Clean Production: ISO 13485-compliant manufacturing with material certification.
Product Applications
Medical Fluid Transfer: Accurate delivery of cell culture media, pharmaceuticals, and reagents.
Microsampling & Microfluidic Chips: Precision handling of minimal-volume liquids.
Dual-Liquid Dispensing: Simultaneous or alternating delivery via double-tube bent needles.
Surface Treatment & Directional Spraying: Controlled-angle dispensing for spatial constraints.
High-Pressure Environments: Leak-free performance in demanding hydrodynamic conditions.
