Analytical Reagents Are Useful In Sophisticated Analytical Instruments And Research Work Where High Purity Is Essential While Lab Reagents Are Useful To Carry Out Lab Analysis.
------
There used to be four grades of chemical: food grade, technical grade, lab grade and analytical grade. Food grade was safe and pure for use in foods, technical was for manufacturing nonfood items, lab grade was for lab research and analytical grade was as pure as they could possibly make. Not all chemicals could achieve all four grades; there was no food-grade arsenic or strontium-90 for reasons obvious. And some chemicals are the same in all four grades - borax, a mild base called sodium metaborate, is as pure in the "20 Mule Team" variety at the store as it is in reagent grade.
Now there are dozens of grades. Google grades of reagents and the first hit is a very large page listing them all.

Laboratory reagents are chemicals used for various purposes in a laboratory, while analytical reagents are specifically designed and tested for analytical techniques like titrations or colorimetric assays. Analytical reagents ensure high purity and accuracy in analysis, whereas laboratory reagents may have broader applications in research and experimentation.

What is the purity difference between hydrogen peroxide AR grade and hydrogen peroxide LR grade?
AR is analytical reagent and LR laboratory reagent; practically differences are not significant and depends on the reagents company.
What is LR or AR grade chemicals?
LR (Laboratory Reagent) grade chemicals are of a lower purity level compared to AR (Analytical Reagent) grade chemicals. LR grade chemicals are commonly used in general laboratory procedures when high purity is not critical, while AR grade chemicals are of a higher purity and are used for analytical testing where accuracy is important.
What general name is given to a laboratory chemical?
A laboratory chemical is typically known as a reagent or a chemical compound.
What compound of nitrogen is used as laboratory reagent?
No2&Nal
What is the function of a reagent bottle in laboratory apparatus?
Reagent bottles are containers made of glass or plastic, and are closed by special caps or stoppers, and are intended to contain chemicals in liquid or powder form for laboratories and stored in cabinets or on shelves.

Under what circumstances should the technical staff check reagent volumes?
In many laboratory experiments: analytical chemistry, biology, medicine etc.
What are the grades in which tartaric acid is available?
Tartaric acid is available in Laboratory Reagent (LR) and Analytical Reagent (AR) grades. You can buy these lab chemicals online in India at best price at ibuychemikals ecommerce website
What is meanings of AR and GR in chemical grade?
AR stands for Analytical Reagent grade, which is typically a high-quality grade used for analytical testing. GR stands for Guaranteed Reagent grade, which ensures batch-to-batch consistency in purity and composition for reproducible results in experiments.
What laboratory tools is used to perform a chemical test on a substance?
Okay,it's the safety goggle and many more,but the most useful of your question is that answer.
What other types of analytical procedures detect the presence of proteins?
biuret reagent

What is the difference between Benedict's Reagent and Biuret Reagent?
Benedicts reagent is used to check reducing sugars , it need hat to work and gives red color when positive ,. While biuret reagent is for proteins .there is no need to use heat and gives purple , violet color when positive ..
