So you don't get water, dirt or other contaminants in the reagent bottle. The reagent bottle should contain chemicals that are as pure as possible. If each person put a dirty spatula in the bottle, the reagent bottle would very quickly accumulate all kinds of junk, ruining the chemicals inside or causing hazardous chemical reactions.
I guess it is spatula
This standard procedure -dry and clean spatula in scooping solid chemicals from reagent bottle- should prevent contamination of - and exposure to dirt and humidity to - the other chemical reagents.
To ensure no other chemicals get into the bottle and react with the solid you are trying to use.
If it is wet, it will get the chemical wet, which will add to its mass, and could cause an undesired reaction. If it is dirty, the substance on the spatula would affect the purity of the chemical, and could cause an unwanted reaction, or could also affect the mass.

This is to prevent contamination of the remaining reagent in the bottle.
It is a heavy glass bottle (unlikely to break or react with the reagent chemicals) used to store moderate amounts of laboratory chemicals (reagents)
used as a container where you put chemicals that can't be thrown in the sink.
used to utilize chemicals
A spatula would be used to remove 0.25 grams of a solid material from a reagent bottle.
