FAQ

Q: What's the lead time for custom quartz labware?

A: It depends on order quantities.

Q: How does quartz compare to sapphire for optical windows?

A: Quartz is more cost-effective with similar UV transparency but lower scratch resistance.

Q: How should I clean custom quartz labware?

A: Use aqua regia (3: 1 HCl: HNO₃) or piranha solution (H₂SO₄: H₂O₂) for tough residues.

Q: What is the typical lead time for custom and standard products?

A: Lead times depend on product complexity, quantity, and current production schedules. Standard items might ship within 7 days. Custom orders typically range from 1 to 4 weeks after drawing approval. We will provide a specific estimated lead time with your quote.

Q: Can you provide material certifications or Certificates of Conformance (CoC)?

A: Yes, we can provide material certifications detailing the properties (like purity) and Certificates of Conformance upon request, confirming that the products meet the specified requirements and standards.

Q: What is your Minimum Order Quantity (MOQ)?

A: Our MOQ varies depending on the product type and complexity. For standard items like tubes or rods, we might have lower MOQs compared to highly customized precision components. Please contact our sales team with your specific requirements for details.
