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.

Standard size ranges cover lengths from 50mm to 2000mm, widths from 20mm to 300mm, and thicknesses from 2mm to 20mm. All dimensions are fully customizable based on customer-supplied drawings.

Q What surface treatment options are offered?

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

Q What accessories are available to complement the quartz products?

We provide quartz support rods, baffles, and lids as part of integrated solutions, ensuring compatibility and optimal performance within your process setup.

Q How do I specify a custom quartz tray or boat for my application?

You can submit your technical drawings or detailed dimensional requirements directly to our team. We will review the specifications and produce the parts according to your exact requirements, including shape, size, slot configuration, and surface treatment.

Q Are grooved quartz trays suitable for wafer or substrate processing?

Yes. Grooved quartz trays with 1 to 100 slots are specifically designed for holding wafers, substrates, or other flat components during high-temperature diffusion, oxidation, or deposition processes, ensuring precise spacing and stable support.
