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 a wide range of shapes, including rectangular, U-shaped, V-shaped, grooved (with 1 to 100 slots), and special customized structures tailored to specific application needs.

Q What is the size range available, and can dimensions be customized?

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

Q What surface treatment options are offered?

Three surface treatment options are available: polished (smooth and highly transparent), frosted (matte, non-reflective finish), and acid-etched (chemically treated for enhanced purity and surface uniformity).

Q What accessories are available to complement the products?

A full range of compatible accessories is available, including quartz support rods, baffles, and lids, enabling complete integrated solutions for your processing or laboratory setup.

Q How many slots can a grooved structure accommodate?

Grooved structures can be manufactured with anywhere from 1 to 100 slots, making them highly versatile for wafer processing, sample holding, and other precision applications requiring multiple compartments.

Q Is it possible to order a fully customized structure not listed in the standard options?

Yes. In addition to the standard shapes and sizes, fully customized structures can be produced based on customer-supplied drawings or design requirements, ensuring the product meets your exact application specifications.
