data-end=\"2959\"><strong data-start=\"2640\" data-end=\"2713\">Q1: Why choose a sapphire tube with a polished OD and fine-ground ID?<\/strong><br data-start=\"2713\" data-end=\"2716\" \/>The polished OD allows optical monitoring or laser applications, while the fine-ground ID provides controlled friction, wear resistance, and better lubricant retention, making it ideal for fluidic systems and precision mechanical assemblies.<\/p>\n<p data-start=\"2961\" data-end=\"3187\"><strong data-start=\"2961\" data-end=\"3026\">Q2: What are the maximum length and diameter you can produce?<\/strong><br data-start=\"3026\" data-end=\"3029\" \/>We can manufacture sapphire tubes up to 250 mm in length and up to \u03c6250 mm in diameter, covering micro-fluidic components as well as large industrial tubes.<\/p>\n<p data-start=\"3189\" data-end=\"3420\"><strong data-start=\"3189\" data-end=\"3249\">Q3: Can you ensure high concentricity between OD and ID?<\/strong><br data-start=\"3249\" data-end=\"3252\" \/>Yes. Our precision CNC grinding ensures concentricity up to 0.02 mm and parallelism as tight as 2 Arc Seconds, critical for high-pressure seals and optical alignment.<\/p>\n<p data-start=\"3422\" data-end=\"3730\"><strong data-start=\"3422\" data-end=\"3500\">Q4: Is the tube resistant to strong acids, such as hydrofluoric acid (HF)?<\/strong><br data-start=\"3500\" data-end=\"3503\" \/>Sapphire is highly resistant to most acids and alkalis, outperforming quartz in durability. For extremely concentrated HF, please consult us for confirmation, but standard semiconductor etching conditions are fully supported.<\/p>\n<p data-start=\"3732\" data-end=\"3977\"><strong data-start=\"3732\" data-end=\"3786\">Q5: Can you produce custom dimensions or drawings?<\/strong><br data-start=\"3786\" data-end=\"3789\" \/>Absolutely. We specialize in custom sapphire components.
