High Purity Fused Silica Quartz Tank Uniform Wall HF Resistant For Wafer Pickling Chemical Digestion Laboratory Reactor

High Purity Fused Silica Quartz Tank

This high purity fused silica quartz tank features uniform wall thickness, double side fine ground surfaces and integrally fused or bonded construction. With ≤1100°C continuous working temperature and superior HF/strong acid chemical durability, it delivers reliable performance for semiconductor wafer pickling, high-temperature sample digestion, chemical reagent reactions and laboratory open calcination—significantly outperforming borosilicate glass alternatives.

Product Parameters

Key Features

• HF & Strong Chemical Resistance – Fully resistant to hydrofluoric acid and concentrated strong acids/alkalis, suitable for prolonged immersion of corrosive reagents that would destroy borosilicate glass tanks.
• ≤1100°C Continuous Operation – Maintains structural integrity under sustained high temperatures for digestion, calcination and high-temperature chemical processes without softening or deformation.
• High Purity, No Contamination – 99.99% pure fused silica with zero heavy metal precipitation, ensuring no cross-contamination during semiconductor wafer processing and high-purity chemical applications.
• Low Thermal Expansion – Excellent thermal shock resistance withstands rapid heating and cooling cycles without cracking, enabling repeated cyclic use in demanding laboratory and industrial environments.
• Smooth Inner Wall – Precision polished interior surface for easy cleaning and minimal residue adhesion, reducing cross-contamination risk between batches.

Applications
