Small opening vials:
small opening vials for storing liquid reagents, so the mouth is relatively small. Available in both clear and brown colors, the brown vials is used to hold reagents that need to be stored in the dark.
Precautions for use: Cannot be used for heating. When taking the reagent, the stopper should be placed on the table, and the stopper should be stoppered and sealed if necessary. Due to the inner frosting of the vials mouth, it is matched with the glass sanding plug, so it cannot hold strong alkaline reagents. If the alkaline reagent is contained, use a rubber stopper instead.
Wide opening vials:
Wide opening vials for holding solid reagents, both transparent and brown. The brown vials is used to hold reagents that need to be stored in the dark.
Precautions for use: Cannot be used for heating. When taking the reagent, the stopper should be placed on the table, and the stopper should be stoppered and sealed if necessary. Because the inside of the vials is frosted and matched with the glass sanding plug, the jar of the glass stopper cannot hold the strong alkaline reagent. If you are holding alkaline reagents, use a rubber stopper!
This is the end of the introduction of Attentions for wide opening vials and small opening vials. I hope it can help you.
