About this product

Product information from the supplier.

Product Overview


Two categories of high-purity Nitric Acid serve distinct customers. Reagent Grade (AR and GR) supports laboratory work where consistent purity determines analytical accuracy. Electronic Grade serves semiconductor and component manufacturing where trace contamination affects product performance. Neither resembles industrial nitric acid – those bulk shipments lack the certified purity documentation that labs and fabs require.

AR (Analytical Reagent) meets standards for routine lab work. GR (Guaranteed Reagent) offers tighter impurity specifications for demanding analyses. Electronic Grade removes metals and particles to levels suitable for wafer processing and component cleaning.

Typical specification: 65% – 70% HNO₃. Each grade ships with a lot-specific Certificate of Analysis.

Grades Available: AR | GR | Electronic Grade


Why Choose Our High-Purity Nitric Acid


Certified Purity, Batch Traceable – Every container includes a COA documenting actual impurity levels. No guesswork – you receive verified data for your quality records.

Three Grades for Different Needs – AR for routine lab analysis. GR for stricter impurity control. Electronic Grade for semiconductor and electronics manufacturing.

Laboratory-Friendly Packaging – Supplied in 500mL, 1L, 2.5L, 5L bottles, and 20L carboys. No need to decant from industrial drums.

Export Track Record – 13 years in chemical exports. Complete documentation supports your quality system.


Solutions We Provide


Trace Metal Analysis by ICP-MS and AAS – Environmental labs testing water, soil, or air filters require acids with low metal backgrounds. Our GR grade provides stable low blanks – essential for EPA method compliance and routine toxicology screening.

Sample Digestion for Elemental Analysis – Soils, biological tissues, polymers, and geological materials must dissolve before analysis. Reagent nitric acid digests organic matrices and solubilizes metals. For complete digestion of refractory samples, it pairs with hydrochloric acid (aqua regia). Our AR and GR grades deliver consistent digestion without introducing analytical interferences.

Electronics Component Cleaning – Electronic Grade Nitric Acid removes oxides and trace contaminants from component surfaces, lead frames, and circuit boards. The purity level prevents residue that could affect electrical performance or subsequent bonding operations.

Wafer Processing and Etching – Electronic Grade Nitric Acid serves as a component in standard silicon etching mixtures. Combined with hydrofluoric acid, it removes silicon at controlled rates. The purity of each chemical directly affects etch uniformity.

Pharmaceutical Quality Control – QC laboratories test raw materials and finished products for heavy metal contamination. Reagent nitric acid prepares samples for compendial heavy metal tests (USP, EP) and instrumental analysis. Batch-specific documentation supports regulatory inspections.

University and Research Labs – Academic labs use reagent nitric acid for digesting organic samples, cleaning glassware, and preparing calibration standards. Small-pack sizes (500mL to 5L) match laboratory workflows – no excess inventory, no contamination risk.


Related Products & Important Notice


Hydrochloric Acid (HCl), AR/GR Grade – Paired with nitric acid for aqua regia digestion; many labs purchase both

Hydrofluoric Acid (HF), AR/GR Grade – Used with nitric acid for silicate digestion; geology and environmental labs may need both

Hydrogen Peroxide (H₂O₂), AR/GR Grade – Used in sample preparation alongside nitric acid for certain digestion protocols

Note: Reagent and electronic grades differ from industrial acid in purity documentation and packaging. Never substitute industrial grade for reagent or electronic grade in analytical work.

Important – Corrosive – Fume Hood Required

High-purity nitric acid is corrosive and an oxidizer. Use in fume hoods. Wear gloves, goggles, and lab coat. Segregate from organics and reducing agents. Store in original containers away from incompatible materials. Contact us for SDS.
