Product Description
316L Stainless Steel Laboratory Spray/Liquid Jet Needle with CNC Milled Luer Connector
Product Overview
The 316L Stainless Steel Laboratory Spray/Liquid Jet Needle with CNC Milled Luer Connector is a precision-engineered, all-metal fluidic component designed for demanding experimental and analytical applications. This unit integrates a needle body optimized for liquid spraying or precise jetting with a robust, leak-proof Luer connector, all machined from a single piece of medical-grade 316L stainless steel via精密CNC milling. The monolithic construction eliminates potential weak points from assembly, while the 316L material provides superior chemical resistance and corrosion stability. The CNC-milled Luer threads ensure a perfect, secure fit with standard laboratory syringes or tubing, making it an ideal, durable tool for controlled fluid delivery in research, chromatography, and micro-dispensing.
Manufacturing Process
- Material Preparation: Selection and cutting of certified 316L stainless steel rod to suitable blank length
- CNC Swiss Machining / Multi-Axis Milling: Complete machining in single setup including turning, milling Luer threads, drilling internal lumen, and forming tip/orifice geometry
- Deburring & Internal Polishing: Meticulous edge deburring and internal bore honing/electropolishing for smooth, contaminant-free fluid flow
- Surface Passivation: Chemical passivation per ASTM A967 to maximize corrosion resistance
- Cleaning, Inspection & Marking: Ultrasonic cleaning, 100% dimensional verification, and laser marking for identification
- Packaging: Clean and dry packaging suitable for laboratory use, available non-sterile or sterilized
Applications
- Analytical Chemistry: Sample introduction needles for GC/MS, HPLC, or ICP-MS systems
- Microfluidic Research: Robust interface for connecting syringes or pumps to microfluidic chips
- Precision Dispensing: Laboratory-scale dispensing of reagents, solvents, or standards
- Spray Characterization Studies: Standardized nozzle for droplet size and spray pattern research
- Chemical Synthesis: Controlled addition of reactants in small-scale or automated synthesis setups
