Our Platinum Iridium Capillary Tubes are built for precision. With a purity of 99.95%–99.99%, these tubes offer exceptional performance. The PtIr5 alloy has a melting point of 1790°C, a density of 21.49 g/cm³, and a tensile strength of 274 MPa, while PtIr10 steps it up with a 1800°C melting point, 21.53 g/cm³ density, and 382 MPa tensile strength. Their hardness (90 HV for PtIr5, 130 HV for PtIr10 in soft state) ensures durability, and their electrical resistivity (19.0 µΩ·cm for PtIr5, 24.5 µΩ·cm for PtIr10 at 20°C) supports stable performance in analytical applications.

These capillary tubes are available in ultra-fine sizes, with outer diameters as small as 0.2 mm and customizable wall thicknesses and lengths. Whether you need a tube for microfluidic transfer in a chromatograph or a robust component for a sensor, we can tailor it to your needs. Our manufacturing process adheres to ASTM B684 standards, and every tube undergoes stringent quality checks to ensure flawless precision. We package them securely in padded cartons or wooden cases to guarantee safe delivery worldwide.

The platinum-iridium alloy’s corrosion resistance is a game-changer. It stands up to harsh chemicals and high temperatures, ensuring contamination-free performance in analytical instruments. The iridium content enhances strength, giving our tubes an edge over pure platinum or glass in high-precision applications.

Platinum is great, but adding iridium makes our tubes exceptional. The 5% or 10% iridium in PtIr5 and PtIr10 boosts strength and wear resistance, making them tougher than pure platinum. Compared to glass, our tubes offer superior corrosion resistance and thermal stability, critical for analytical instruments handling aggressive chemicals. Glass is cheaper but brittle and less durable, while our platinum-iridium tubes deliver long-term reliability and precision.

Customization is where we shine. Need a capillary tube with a specific inner diameter for a mass spectrometer? We’ve got it. Want a particular length for a chemical sensor? No problem. Our advanced manufacturing techniques, like precision drawing and laser micromachining, ensure tight tolerances that meet the strictest analytical standards.
