Chemical Reagents For The Use Of Reagent Bottles

- Jul 31, 2019-

HF solution can not be used for glass bottles due to corrosion of glass. Plastic bottles or lead plates can be used. Other reagents are generally stored in glass bottles.

1. Reagent bottle requirements

The HF solution cannot be used for glass bottles due to corrosion of the glass. Plastic bottles or lead plates can be used. Other reagents are generally stored in glass bottles.

2. Requirements for reagent bottle mouth

The general solid reagent is stored in a jar and the general liquid reagent is stored in a vial.

3. Requirements for reagent bottle stoppers

For reagent bottles containing alkaline substances (such as NaOH, Na2CO3, Na2S, etc.) or water glass, use rubber stoppers and cork stoppers. Because both the alkaline material or the water glass react with the silica in the glass, the bottle and the plug are bonded.

It is advisable to use a glass stopper without special instructions.

4. Reagent bottle body color requirements

Reagents that are easily decomposed by light should be stored in brown jars and vials. Such as AgNO3, chlorine water, hydrogen peroxide, bromine water and unstable organic matter, etc., the rest are generally stored in a colorless reagent bottle.

5. Use of dropper bottles

Dropper bottles cannot store liquid reagents that are prone to evaporation, volatilization, and corrosive to the rubber head. Dropper bottles generally do not require long-term storage of reagents. Reagents that are easily decomposed by light should be stored in a brown bottle.
