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

Q What shapes are available for the quartz boat or tray products?

The products are available in multiple standard shapes including rectangular, U-shaped, and V-shaped profiles. Grooved versions with 1 to 100 slots can also be manufactured, and fully customized structures are supported based on customer-supplied drawings or specifications.

Q What size range can be manufactured?

Standard manufacturing supports lengths from 50mm to 2000mm, widths from 20mm to 300mm, and thicknesses from 2mm to 20mm. All dimensions are customizable to meet specific application requirements based on customer drawings.

Q What surface treatment options are offered?

Three surface finish options are available: polished (high-clarity, smooth surface), frosted (matte, diffuse finish), and acid-etched (chemically treated for enhanced surface properties). The appropriate finish can be selected based on your process or application requirements.

Q Are accessories available to complement the main product?

Yes. A range of compatible accessories is available, including quartz support rods, baffles, and lids. These components are designed to work together as an integrated solution for semiconductor, laboratory, or industrial processing environments.

Q Can products be customized according to specific engineering drawings?

Absolutely. Custom fabrication is a core capability. Customers are welcome to submit their own engineering drawings or dimensional requirements, and products will be manufactured accordingly — including non-standard shapes, slot configurations, and dimensions outside the listed standard ranges.

Q How many slots can a grooved product have, and what are typical applications?

Grooved products can be manufactured with anywhere from 1 to 100 slots. These are commonly used in semiconductor wafer processing, such as wafer boats for diffusion furnaces, CVD systems, or wet bench applications, where precise wafer spacing and support are critical.
