Quartz Glass Rods & Custom Fabrication FAQ
Got questions regarding quartz rod dimensions, tolerances, chemical purity, or shipping safety? Find clear technical answers below.
What is the difference between standard quartz rods and synthetic fused silica rods?
Standard quartz rods are manufactured from natural high-purity crystalline quartz ore, ideal for thermal furnaces (up to 1200°C) and visible light applications. Synthetic fused silica rods are synthesized via chemical gas vapor oxidation, featuring >99.9999% purity and extraordinary deep UV transmission down to 190nm with zero bubble inclusion.
Can Southeast Quartz customize rod diameters, slots, and bendings according to technical drawings?
Yes, absolutely. We support complete customization from Φ0.5mm micro-rods to Φ150mm large quartz bars. Our factory is equipped with multi-axis CNC machines for complex spiral cutting, grooving, end-ball forming, fire polishing, and high-precision threading according to your CAD/STEP files.
What is the thermal shock limit of your quartz rods?
Because of fused quartz's near-zero thermal expansion coefficient (5.5 × 10-7 / °C), our quartz rods can be heated to 1100°C and plunged directly into 20°C cold water without cracking or fracturing, making them supreme for thermal cycling equipment.
How are long and fragile quartz rods packaged for international export?
We use multilayer protective packaging: each quartz rod is wrapped in dust-free PE film, packed in shock-absorbing pearl cotton / EPE foam custom slots, and enclosed in heavy-duty international standard export wooden crates to ensure zero breakage during global air or sea transit.
