This is a high-precision, modular fluid delivery component designed for laboratory research, analytical instrumentation, and pilot-scale medical device development where customizable spray performance and secure connection are critical.
Experimental & Research Equipment: Used as a precision nozzle in prototype nebulizers, lab-scale spray dryers, aerosol generation systems, and micro-dispensing setups for drug formulation research.
Analytical Instrumentation: Serves as a sample introduction spray needle in mass spectrometry (ESI, APCI sources), chromatography detectors, or chemical analysis devices.
Medical Device Prototyping: Acts as a functional component in developing new surgical irrigation devices, inhalers, or cosmetic micro-spraying tools before mass production.
Industrial R&D: Applied in coating technology research, fuel injector testing, or any application requiring precise, adjustable liquid atomization.
Product Description:
We provide custom CNC milling services to produce precision hexagonal-threaded spray needles from 304 stainless steel. This component is engineered for experimental and low-volume production applications, offering a balance of performance, durability, and customization. The design integrates a hexagonal threaded body for tool-assisted assembly and secure, leak-free mounting into a matching manifold or handpiece, and a precision-machined spray tip (conical, cylindrical, or with a jewel orifice) for controlled atomization. The internal flow channel is optimized for consistent performance. Made from corrosion-resistant 304 stainless steel, it is suitable for use with a wide range of chemicals and can be sterilized. The hexagonal profile allows for easy integration and adjustment in experimental setups. We offer full customization of all dimensions, thread specifications, spray angle, and orifice size to meet exact research or prototype requirements.
