This chemical solution represents our commitment to providing consistent, high-specification products designed for demanding technical and industrial workflows.

Why This Grade

The choice of ACS Reagent Grade with a strict 70% concentration is critical for processes that cannot tolerate variation or impurities. In semiconductor manufacturing, metal finishing, and quantitative chemical analysis, even part-per-million levels of metallic impurities or microscopic particulates can cause catastrophic failures. Utilizing a lower-grade acid, such as technical or industrial grade, introduces unwanted trace contaminants like iron or chloride. These impurities can alter the rate of chemical reactions, degrade silicon wafers during etching, or corrupt baseline data in analytical spectrometers.

Furthermore, the precise 70% concentration provides the optimal thermodynamic and chemical activity required for controlled oxidative reactions and passivation. Utilizing a weaker concentration or an inconsistent blend can result in incomplete passivation, leaving stainless steel vulnerable to premature corrosion and structural failure. In laboratory settings, variance in concentration directly compromises the stoichiometry of syntheses, leading to low yields or failed batches. For operations that require absolute reliability, this low-particle ACS grade eliminates these operational failure modes, ensuring consistent and predictable performance in every application.

Industrial Applications

• Semiconductor and Electronics Manufacturing: Employed as a high-purity etching agent and surface cleaning chemical for silicon wafers to remove microscopic metallic contaminants without leaving residues.
• Metal Finishing and Passivation: Used in the aerospace and automotive sectors to passivate stainless steel surfaces by selectively dissolving free iron and forming a protective oxide layer.
• Analytical Laboratory Chemistry: Serving as a vital reagent for sample digestion prior to trace metal analysis using Inductively Coupled Plasma Mass Spectrometry or atomic absorption.
• Chemical Synthesis: Acting as a key precursor and nitrating agent in the manufacture of various organic and inorganic compounds, polymers, and specialty chemical intermediates.
• Industrial Equipment Descaling: Utilized in critical maintenance protocols to dissolve hard calcium deposits and metal oxides from specialized industrial heat exchangers and processing lines.

Hazmat & Shipping

Nitric Acid 70% ACS Grade - Low Particle is a highly regulated hazardous material classified under international transport protocols. This chemical is shipped as UN2031, Hazard Class 8, with Packing Group II. The official proper shipping name is Nitric acid, other than red fuming, with at least 65 percent, but not more than 70 percent nitric acid. Due to its corrosive and oxidizing nature, the GHS signal word is Danger, and it carries the GHS pictograms for Oxidizer, Corrosive, and Acute Toxic. These classifications highlight the critical necessity of strict adherence to all DOT and international shipping guidelines to ensure safe transit and delivery.

When handling this material, personnel must use appropriate personal protective equipment (PPE) as dictated by the GHS classification codes. Keyed to hazard statement H314 Causes severe skin burns and eye damage [Danger Skin corrosion/irritation] and H330 Fatal if inhaled [Danger Acute toxicity, inhalation], operators must wear chemical-resistant gloves, full protective suits, and goggles or face shields. Since it is a powerful oxidizer that May cause fire or explosion; strong oxidizer (H271) and May intensify fire; oxidizer [Danger Oxidizing liquids; Oxidizing solids] (H272), it must be handled away from combustible materials and organic substances. Respiratory protection is mandatory when handling this material in non-ventilated areas to avoid the severe risk of inhalation.

Handling & Storage

Safe handling of this concentrated mineral acid requires strict storage protocols. Nitric Acid 70% must be stored in cool, dry, well-ventilated facilities, ideally within a temperature range of 50°F to 80°F, away from direct sunlight. Container compatibility is crucial; the chemical must be kept in its original fluoropolymer, glass, or specially treated stainless steel containers. It is highly incompatible with organic materials, combustible substances, strong bases, active metals, and reducing agents, as contact can lead to violent, exothermic reactions or the evolution of hazardous nitrogen oxides.
