Dear Readers, Welcome to the latest issue of The Magazine
As in the case of running a pharmaceutical lab, performing clinical diagnostics, or doing academic research – getting the right grade of reagents and chemicals is crucial.
Selecting the correct grade of reagent can make or break your experimental results. Chemicals come in various grades, while each grade denotes a level of purity or a certain degree of contaminating materials alongside water.
Selecting the right grade ensures accuracy, precision, compliance with industry best practices, protective measures for expensive instruments, and efficient budget allocation on lab resources.
Select the wrong grade, and you’ll achieve inaccurate and irreproducible experimental results – while compromising reputation, safety, and finances.
Reagents and chemicals can be categorized based on their intended purposes as using a lower grade for high precision tasks could lead to completely contaminated, faulty, and dangerous data.
Dedicated to the most delicate and cautious analytical approach, this would include meticulous, gracious, patient, and orderly dealing with substances.
This straightforward yet profound precision is what allows common laboratory tools and equipment to serve their broad and versatile purposes: they are not bound to a single method of operation. Instead, they adopt various principles while being designed for a specific object of analysis.
The advantage with dealing with AR-grade chemicals is they are often free of any contaminating materials for interventional laboratory results.
GR has the same level of purity as AR-grade and is a European standard. It is GR that is the most accepted standard in scientific research, diagnostics, and other chemical analysis because of its consistency and reliability.
The HPLC grade of reagents are specially purified to get rid of impurities that absorb UV light. These are important in both chromatographic and spectrophotometric methods that need little background interference.
These reagents are used in UV/Vis and other types of spectroscopy. Spectroscopy grade reagents are designed to have very low absorbance at a wide range of wavelengths of light to enable accurate measurements with light.
This grade describes a product that meets the standards of United States Pharmacopeia and National Formulary. It is important for pharmaceutical manufacturing and any other usage where compliance to regulation is important.
These are the chemicals that are mostly used for general purposes in the laboratory and do not require high purity. They are appropriate for buffer preparation, cleaning procedures, some teaching experiments, and other routine activities.
These are the lowest purity industrial chemicals that are meant for use in manufacturing, cleaning, or any non-critical processes. Because of the low purity they are the least recommended for scientific or clinical applications.
The grade of chemical a person uses in the laboratory depends on the specific procedures they are conducting. Follow these recommendations:
A lab grade chemical is an important for any industry that at some a stage utilizes a laboratory and is using different types of equipment, hence it is very important to understand the varying grades of laboratory reagents and chemicals. The appropriate reagent aids in securing your results as well as ensuring the safety of your instruments while complying with industry regulations.
Default by following the instructions of regulatory documents, methods’ specifications, or trusted suppliers who can aid in merging the appropriate reagent grade with your requirements.
