Ensure following guidelines given below while handling reagents and chemicals
- As far as possible, use the smallest packing of chemical that would supply the desired quantity.
- Replace the cap or stopper of the bottle immediately after taking out your requirement.
- Stoppers of reagent bottles should never be placed on the desktop.
- Do not insert spatulas or pipettes in reagent bottles. Takes out a slightly excess amount in another container from where use the required quantity.
- Some reagents require special storage conditions, such as dark color bottles for light sensitive chemicals or low temperature for solvents and reagents subject to microbial degradation.
- Do not use a reagent after the recommended shelf life of sensitive chemicals.
- Dry the solid chemicals for making solutions, in a suitable container, as directed in the standard analytical procedure.
