The reagent grade, which is the highest high-quality chemical, is suitable for all purposes and is employed for carrying out scientific experiments on living organisms.
The laboratory grade chemical compounds can be applied for all non-biological activities. Nevertheless, it is unfit to be packed and sold for consumption purposes.
The third is the technical grade, which is mainly utilised for industrial and manufacturing purposes. Also useful in laboratories, when higher levels of accuracy are essential.
At times, there is not substantially difference involving the reagent and technical grade, other than the fact that the former has been tested for purity even though the latter hasn’t.
Providing appropriate packaging:
Chemical substances are sold making use of unique strategies. Some chemical substances which are dry at STP are sold in a powdered kind. These are wrapped or sealed in zipped bags. Other chemical substances, which are in a liquid state, are sold in:
