Classification of Laboratory Reagents

Laboratories stock reagents whose categories differ. Classifying lab reagents is vital to avoid errors and extra costs in laboratory tasks.

There are two ways of classifying lab reagents, namely purity and the intended purpose.

On the basis of purity, the following are some of the sub-groups;

Technical class-for basic uses such as cleaning or as a solvent

Synthesis class-for preparation of substances used in the lab.

Laboratory class-basically the solvents used for the various lab tasks.

A R Class-these are the purest in the group as impurities would result in errors while conducting vital applications such as research and quality control.

ACS class-these are reagents that satisfy the high quality checks set by the American Chemical Society.

General Reagent-a class of reagents whose purity matches that of the AR class reagents.

Extra pure class-these reagents are required in granting recognition to labs that comply with set standards

Based on their purpose, the following classes arise:

Electronic class-reagents with strict amounts of metallic impurities with uses in electronics industry

HPLC class-specifications of these reagents used for HPLC applications include UV absorption limits and free of sub-micron solids

Spectroscopy class-highly pure reagents, leave no residue employed in spectroscopic purposes

Acids-include suprapur acid and environmental acids

Pesticide class of solvents

It is vital to select the right reagent for a particular application to guarantee precision and accuracy of outcome.
