PREPARATION OF REAGENTS The following general instructions are applicable in the preparation of all reagents Use graduated cylinders or pipettes closest to the volume being measured for preparing liquid reagents Store all reagents in sterile containers unless otherwise noted
What is the procedure for preparation of reagent solutions?
To lay down the procedure for preparation of Reagent solutions. 5.1 The solution shall be prepared by the chemist who actually does the analysis. The solution shall be prepared when it is required. 5.2 The quantity of the reagent depends on the requirement of the test.
What are laboratory reagents?
Usually, laboratory reagents consist of a wide range of organic and inorganic reagents in preparative chemistry and other diverse field. It's range covers all the chemicals required on day-to-day basis of all types of chemical laboratories.
What should be included in a reagent label?
Many procedures include formulas for reagent preparation. Labels for reagents prepared in-house must contain the following: Name of solution. Date of preparation. Expiration date (if known). Storage temperature and/or conditions. Mechanism to identify the person who prepared the solution. Universal hazardous substance label.
How to store reagent?
5.5 Storage condition for reagent shall be followed as specified, and light resistant bottles, refrigerator etc. shall be used wherever required. 5.6 All the reagent solution shall be stored stating the name of the solution, strength, normality, molarity (if there), prepared by name, sign, date of preparation and to be used before.
