Sample preparation is as important as the analysis of your sample. Make sure you use the right reagents to avoid contamination of your sample.

The right choice of chemical is crucial for your chromatography process. Below an overview of our chemical range for chromatography.

In gas chromatography, sample preparation is critical to obtain the right result. Choosing the right chemicals for your method and application will help you for a succesful analysis.

Everything you need for this common quantitative technique from classical glassware to automatic titrators, including reagents and accessories.

Choice of compact volumetric or coulometric Karl Fisher titrators and related reagents for water determination.

pH measurements using a pH meter can only be correct and precise when you are using the right buffer for your instrument.

Conductivity measurement of an aqueous solution is a method used to determine amount of nutrients, salts and impurities. Conductivity standards are crucial to calibrate your conductivity meter.

Many different ranges for physical measurements: Viscosity standards, melting point standards, density standards, refractive index and Brix standards are available.

UV/Vis analysis with a spectrophotometer can require different types of chemicals. First, a specific grade of solvents is developed to avoid optical impurities of your sample. Second, the spectrophotometer...

NMR (Nuclear Magnetic Resonance) is used as a standard analysis method for structural determination of an organic compound.

For the sample preparation of your XRF analysis, you can use borates for fusion, additives for fusion and pre-weighted tablets for grinding and tabletting.

In metal analysis, elemental evidence is now gathered from the tiniest traces in the ppm, ppb and ppt ranges with sophisticated instrumentation like AAS, ICP-OES or, more recently, ICP-MS.

If you’re creating new molecules in your pharmaceutical or chemical research or university laboratory, VWR offers an extensive range of products to help you with your discoveries.

The Kjeldahl method is used to determine the nitrogen content of a sample. In this analysis, the sample is digested with a strong acid and the free nitrogen reacts to form ammonium sulfate.

Dissolution media preparation can be a time consuming task when done manually. J.T.Baker® DILUT-IT™ dissolution media concentrates are pre-mixed concentrates that significantly reduce...
