High-Quality Analytical Testing Products from Top Brands

Analytical testing methods help Iabs and researchers identify and monitor acidity and ion concentration, water content, and many other properties of a range of sample types.

Karl Fischer titration, pH, and ASTM methods are frequently used analytical techniques used during water testing and environmental analysisfood and beverage testing, pharmaceutical production, production of cosmetics, petroleum, building materials, and more, as well as clinical research.

Accurate, consistent outcomes are mandatory, and efficiency is just as important. The analytical testing chemicals and lab products you choose help deliver the outcomes you need, and boost confidence that your samples won't be wasted.

pH & ElectrochemistrypH & Electrochemistry

pH and electrochemistry meters and related products are used to assess acidity and alkalinity, conductivity, specific ion concentrations, and dissolved oxygen in water, wastewater, and other solutions.

Electrodes must be carefully stored and maintained for optimal performance. It’s important to select the right storage bottles and electrode filling, cleaning, rinsing, and storage accessories.

Electrochemistry meters also require regular calibration and maintenance. Standard and certified pH buffers as well as conductivity and specific ion standards are available. Other accessories include electrode supports, bulb guards, cables, connectors, and adapters.

Karl Fischer TitrationKarl Fischer Titration

Karl Fischer titration is used with a range of sample types to determine trace amounts of water in samples. Labs and researchers use two types of Karl Fischer titration based on a sample's properties.

Coulometric KF titration is ideal for liquid and gaseous samples with low water content (up to 2%). Water content is measured by electrical current, and the instrument's cell is made from glass with grounded joint connections that ensure a tight seal against air moisture.

Volumetric KF titration is used with solid, liquid and gaseous samples with high water content (over 2%). Water content is measured by burette instead of electrical current, and the instrument's cell construction differs from a coulometric titrator.

ASTM StandardsASTM Standards

ASTM test methods are definitive procedures that produce a result. They usually include a detailed description of a procedure for determining a property or constituent of a material, an assembly of materials, or a product. These details include the apparatus, test specimen, procedure, and calculations needed for satisfactory results.

ASTM test methods represent a consensus about the best currently available procedure and are supported by experience and data from cooperative tests.

The ASTM publishes six types of standards: test method, specification, classification, practice, guide, and terminology.
