Ultra Pure Acids for Semiconductor Manufacturing

Ultra Pure Acid Systems are specialized chemical process units designed for the production, handling, and delivery of high-purity acids required in semiconductor, electronics, and high-tech industries. These systems ensure that acids like HCl, HNO?, H?SO? meet stringent purity standards, free from metallic contaminants, particulates, and moisture.

These systems use borosilicate glass construction, PTFE-lined piping, and high-precision dosing modules to maintain chemical integrity. They are engineered for laboratory, pilot plant, or full-scale industrial operation.

Key Design Features:

• Corrosion-resistant materials for handling ultra-pure acids
• Modular construction for scaling from pilot to production
• Temperature-controlled vessels for precise chemical processing
• Closed-loop systems to prevent contamination and ensure safety
• High-precision feed and metering pumps for accurate acid delivery
