"The custom quartz boats and slotted carriers matched our CAD drawings perfectly. Tolerances were well within ±0.05 mm, and surface finish exceeded expectations for our wafer diffusion runs. Very solid shock-absorbent packaging."
Verified Order: Custom Quartz Boat"Ordered JGS1 optical quartz plates with custom laser grooving and micro-holes. The edge chipping was almost zero and transmittance in deep UV was fully certified. Communication from Zunex engineering was quick and helpful."
Verified Order: Optical JGS1 Plates"High-purity quartz tubes with custom flange connections arrived safe and intact. Thermal shock resistance at 1150 °C is steady with zero devitrification issues after repeated high-heat cycling. Will reorder regularly."
