FAQ
Q1: What's the lead time for custom quartz labware?
A: it depends on order quantities.
Q2: How does quartz compare to sapphire for optical windows?
A: Quartz is more cost-effective with similar UV transparency but lower scratch resistance.
Q3: Are threaded or ground-glass joints possible?
A: Yes – We machine custom interconnects (e.g., ISO-KF, Conflat flanges).
Q4: How should I clean custom quartz labware?
A: Use aqua regia (3:1 HCl:HNO₃) or piranha solution (H₂SO₄:H₂O₂) for tough residues.
