30/410 Nasal Spray Pump Mist Sprayer with Colorful Cap Non Spill Bottle Stopper with Long Nozzle for Screw-On Closure

**Ideal Particle Size:** Atomizes medication into golden-scale particles of 10-70 micrometers, preventing both exhalation and direct flow into the throat.

**Brain-Targeted Delivery:** Advanced chip technology generates ultrafine droplets of 10-50 micrometers, specifically targeting the olfactory region for naso-brain delivery.

**Avoid Lung Deposition:** The Laval nozzle design precisely controls the particle size to be greater than 10 micrometers, ensuring vaccines or medications only work in the nasal cavity and do not enter the lungs.

**High Atomization Efficiency:** The optimized nozzle design achieves an atomization rate of 300 μl/s, suitable for large-scale vaccination scenarios.

**Uniform Particle Size:** The nanochip nozzle has regularly spaced micron-sized pores, resulting in a narrower and more uniform particle size distribution compared to traditional vortex nozzles.

**Low-Speed ​​Soft Mist:** The slow-moving mist generated by the chip nozzle significantly reduces irritation and waste when impacting the nasal flap area.

**Low-Speed ​​Soft Mist:** The slow-moving mist generated by the chip nozzle greatly reduces irritation and waste when impacting the nasal flap area. Adjustable spray angle: The nozzle design determines the plume angle; a smaller angle (e.g., 15°) allows for more concentrated and deep penetration into the nasal cavity.

Large coverage area: At a 50° delivery angle, the nozzle achieves maximum spray area (SA) within the nasal cavity, covering a wider mucosa.
