Ferroxyl Test Solution with Nitric Acid

The Ferroxyl Test Solution with Nitric Acid, often referred to as a Ferroxyl Test, specified in ASTM A 380-99, section 7.3.4, is a chemical solution used to detect the presence of iron in materials or surfaces. It's primarily employed to identify the presence of free iron or iron contamination on surfaces, particularly in industries where the prevention of iron contamination is crucial, such as in the food and pharmaceutical industries.

Ferroxyl Test Solution with Nitric Acid contains 3% by weight Potassium Ferricyanide (ACS reagent grade) along with 3% by weight Nitric Acid (ACS reagent grade) in 94% distilled water .

The kit is configured to use the containers as provided. Nothing else is needed other than standard safety equipment used in all quality labs such as gloves and goggles. The kit is complete.

Ferroxyl Test Kit - 1L: Deionized Water: 500 mL 2.8% Nitric Acid ACS Grade: 500 mL Potassium Ferricyanide ACS Grade: 30 g

Ferroxyl Test Kit - 4L: Deionized Water: 2000 mL 2.8% Nitric Acid ACS Grade: 2000 mL Potassium Ferricyanide ACS Grade: 120 g

Common Uses and Applications

Food Industry: Ensuring that equipment used in food processing, storage, or packaging is free from iron contamination, which could compromise food safety or alter food quality.

Pharmaceutical Industry: Verifying that surfaces and equipment used in pharmaceutical manufacturing processes are free from iron contamination to prevent potential reactions or contamination of sensitive pharmaceutical products.

Metalworking and Manufacturing: Checking the surfaces of metal parts, machinery, or tools for iron contamination, which could cause corrosion or compromise the integrity of finished products.

Paints and Coatings Industry: Verifying that surfaces to be painted or coated are free from iron contamination, which could affect the adhesion and quality of the coatings.

Chemical Processing: Ensuring that vessels, pipelines, or equipment used in chemical processing are free from iron contamination to prevent undesirable reactions or product contamination.

Quality Control: Used as a quality control measure in various industries to ensure the absence of iron on critical surfaces and materials.
