3 What is a reagent?

4 A reagent is a test substance or compound that is added to a system in order to bring about a reaction or to see whether a reaction will occur.

5 A “reagent-grade” describes chemical substances of sufficient purity for use in chemical analysis, chemical reactions, or physical testing.

6 Grades of Reagents

7 There are eight different categories of chemical grades: General Acids High-Pressure Liquid Chromatography and Spectrophotometry Multiple Application Solvent Pesticide and Residue Standard Solutions Bio Tech Applications Miscellaneous

8 Reagent A.C.S. Guaranteed Reagent (GR) AR Primary Standard Reagent OR Purified Practical Lab Grade USP USP/GenAR NF FCC CP (Chemically Pure) Technical General Grades of Chemicals

9 OmniTrace Grade Acids Tracemetal Tracemetal Plus Suprapur Grade Acids AR Select AR Select Plus Environmental Grade Environmental Grade Plus Acids

10 OmniSolv HPLC Grade Solvents HPLC/Spectro ChromAR SpectrAR High Pressure Liquid Chromotagraphy & Spectrophotometry

11 OmniSolv Grade Solvents Absolv UltimAR Accusolv Multiple Application Solvents

12 HR-GC OmniSolv Grade Solvents Nanograde Residue Grade Solvents Pesticide and Residue

13 Standardized StandARd Acculute Standard Solutions

14 OmniSolv Biosynthesis GenAR Accugen BIO Anhydrosolv DriSolv Bio Tech Applications

15 ScintillAR SilicAR Accutint Miscellaneous

16 DO Use the appropriate size container for the job. Get help when needed. Clean containers after use with deionized water. Work under a fume hood unless you have been told otherwise by the lab manager/supervisor. Use a funnel when pouring chemicals into a small container. Open bottles slowly to avoid spilling and allow vapors to escape. Know what type of reactions to expect. Remember to triple-A (AAA): Always Add Acid to water. Lab Chemical Safety

17 DON'T Reuse containers (adverse chemical reaction may occur). Eat, drink, smoke, or touch any body part before washing your hands when working with chemicals. Be afraid to ask questions. Pour leftover chemicals back in its source container, contamination may result. Put your face close to the bottle when pouring. Puncture cap or lid of any bottle.

18 All solution labels meet all ISO, DOT and OSHA regulations and include the following information: Expiration Date Date of Manufacture Standard Reference Material used Actual Lot Analysis Space for date received and date opened NFPA diamond Reagent Labels

19 Example of a Reagent Label

20 Below are so of the containers used for reagents: 4L Amber Glass Bottle Plastic Bottle and Jug 10 L Plastic Container 1 gallon F Can Reagent Containers

21 Rieke Can Hed-Pak Carton with Liner Cubitainer

22 Material Safety Data Sheet (MSDS) These sheets contain all the pertinent information for the reagent. These must be kept in the lab where the reagent is stored. Material Safety Data Sheet (MSDS)

23 OSHA OSHA began requiring MSDS's for hazardous materials effective May 26, 1986. OSHA is responsible for the Hazard Communication Standard 29 CFR 1910.1200. "to ensure that the hazards of all chemicals produced or imported are evaluated, and that information concerning their hazards is transmitted to employers and employees. This transmittal of information is to be accomplished by means of comprehensive hazard communication programs, which are to include container labeling and other forms of warning, material safety data sheets and employee training." The Hazard Communication Standard (HCS) specifies the required elements that must be on an MSDS among other important data.

24 American Society for Testing and Materials (ASTM), is an international standards organization that develops and publishes voluntary consensus technical standards for a wide range of materials, products, systems, and services.

25 Fisher Scientific


27 Reagents at Kennesaw All reagents, etc. are ordered through a unified software system. The reagent is bar coded and tracked through the system to its storage location. Expiration dates are automated through the system and alert the user that these particular items need to be checked. The grade ordered depends on the application. High grades are normally ordered in just the quantity needed because of high cost.
