What information do you need to engineer a custom quartz tube or component?

Please send outer and inner diameter (or wall thickness), length, required tolerances, end configuration (open, closed, flanged, ground joint or welded fittings), material grade (transparent or opaque fused quartz), working temperature and atmosphere, annual or batch quantity, and a drawing in PDF, DWG or STEP format. Complete data lets our engineers confirm manufacturability and lead time in a single review.

What is the maximum operating temperature of fused quartz?

Transparent fused quartz typically supports continuous service around 1,100 °C and short exposures up to roughly 1,250 °C, with a softening point near 1,683 °C. Real limits depend on grade, load, atmosphere and cycle time. Above about 1,100 °C, surface contamination such as alkali residue from skin contact accelerates devitrification, so quartzware should be cleaned and handled with clean gloves before firing.

How does Southeast Quartz verify quality before shipment?

Products undergo helium mass-spectrometry leak detection, pressure resistance testing and purity testing before leaving the factory, together with dimensional inspection against the customer drawing, to ensure stable performance with no impurities and no leakage.

Can you manufacture oversized quartz tubes and non-standard quartz shapes?

Yes. Our workshop combines flame hot-working with CNC cold machining, so we produce oversized fused quartz tubes, bell jars, slotted quartz boats, flanged reactors, irregular shaped quartz sheets and fully customized quartz instruments according to customer equipment parameters.

Where is Southeast Quartz located and which markets do you export to?

Our factory is at No. 1 Qingsheng Rd., Qinghu Industrial Park, Donghai County, Jiangsu, China, within China's best-known crystal and quartz industrial cluster. Besides customers throughout China, we export to Europe, the Americas, Southeast Asia and the Middle East.

? Frequently Asked Questions

Q1 What shapes are available for the quartz boats or trays?

We offer a wide variety of shapes including rectangular, U-shaped, V-shaped, and grooved designs with 1 to 100 slots. Custom structures can also be fabricated based on your specific application requirements.

Q2 What are the available size ranges, and can dimensions be customized?

Standard dimensions range from 50mm to 2000mm in length, 20mm to 300mm in width, and 2mm to 20mm in thickness. All dimensions are fully customizable according to customer-provided drawings or specifications.

Q3 What surface treatment options are offered?

Three surface finishes are available: polished (smooth, high-clarity finish), frosted (matte, non-reflective surface), and acid-etched (chemically treated for enhanced purity and cleanliness). The best choice depends on your process environment and cleanliness requirements.

Q4 What accessories are available to complement the main quartz components?

We provide a complete set of compatible accessories including quartz support rods, baffles, and lids. These are designed to work seamlessly with our main quartz products, offering integrated and reliable solutions for your system setup.

Q5 Can I request a fully customized quartz structure not listed in the standard options?

Yes. In addition to standard shapes and sizes, we accept fully custom orders based on client drawings or design specifications. Our engineering team will review your requirements and provide a tailored solution to meet your exact needs.

Q6 How many slots can a grooved quartz piece have, and what are the use cases?

Grooved quartz products can be manufactured with anywhere from 1 to 100 slots. These are commonly used in semiconductor wafer processing, solar cell manufacturing, and laboratory applications where precise wafer or substrate spacing is required.
