METICULAB Sapphire & Ruby Orifices | Micro-Hole ID 0.03mm ±0.002mm Tolerance
Ultra-Precision Sapphire Orifices — Micro-Hole ID Down to 0.03mm with ±0.002mm Tolerance
METICULAB precision sapphire and ruby orifices are engineered for applications demanding extreme flow control accuracy. With hole diameters as small as 0.03mm and tolerances as tight as ±0.002mm, these micro-components deliver consistent, repeatable flow characteristics across millions of cycles — even in abrasive, corrosive, or high-pressure environments.
⭐ Key Features & Advantages
Extraordinary inner diameter accuracy of 2 microns ensures highly predictable and repeatable flow rates for gases and liquids.
Ultra-fine drilling capability supports high-resolution inkjet printing, particle counting, and precise micro-dispensing applications.
Virtually immune to erosion and deformation. Ideal for high-pressure water jet cutting and abrasive fluid control — significantly longer lifespan than metal nozzles.
Optimized spray patterns and fluid dynamics with specific cone angles and depth profiles machined to your CAD specifications.
100% resistant to most acids, alkalis, and corrosive reagents. Zero sample contamination — meets strict laboratory and medical standards.
Precision lapping ensures clean, sharp edges for accurate flow characteristics and minimal turbulence — consistent performance across millions of cycles.
