NEWSReagent Bottles - Chemical Reagents - Requirements for the Use of Reagent Bottle
1. Requirements for the quality of reagent bottles
HF solution cannot be placed in glass bottles due to corrosion of glass, plastic bottles or lead containers can be used. Other reagents are generally stored in glass bottles
2. Regarding
Reagent BottleRequirements for Bottle MouthGeneral solid reagents are stored in wide mouthed bottles, and general liquid reagents are stored in fine mouthed bottles.
3. Requirements for Reagent Bottle Stoppers
Reagent bottles containing alkaline substances (such as NaOH, Na2CO3, Na2S, etc.) or water glass should be filled with rubber or cork stoppers.
Because alkaline substances or water glass can react with silica in the glass, causing adhesion between the bottle and the stopper.Glass stoppers are preferred without explanation.
4. Requirements for the color of the reagent bottle body
Reagents that are easily decomposed under light should be stored in brown wide mouthed or fine mouthed bottles. Products such as AgNO3, chlorine water, hydrogen peroxide, bromine water, and unstable substances are generally stored in colorless reagent bottles
5. Use of Drip Bottles
Drip bottles should not store liquid reagents that are prone to evaporation, volatilization, and have a corrosive effect on the adhesive head.
. Drip bottles are generally not used as long-term storage reagents. Reagents that are easily decomposed by light should be stored in brown bottles
