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.
AR is analytical reagent and LR laboratory reagent; practically differences are not significant and depends on the reagents company.
The laboratory reagent grade are specified according to their purity. The common commercial grades of reagents are as follows.. AR- analytical reagent grade OR-organic reagent IP - pharmaceutical reagent grade LR- laboratory grade CP- Chemically pure
The general name given to a laboratory chemical is a REAGENT.

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.

In many laboratory experiments: analytical chemistry, biology, medicine etc.
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
AR grade means Analytical grade it is highly pure or enough pure to carreid out any analytical test at the same time GR is stands for Guarnted reagent which is superior grade to perform any test.
Okay,it's the safety goggle and many more,but the most useful of your question is that answer.
biuret reagent
The general name given to a laboratory chemical is a REAGENT.
1)they are use to form laboratory salt when combined with acid. 2)they are used to detect the chemical reagent. 3)they are use to manufacture many laboratory 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 ..
