Since reagent bottles are only used for normal temperature storage reagents, they are usually made of sodium calcium plain glass. In order to ensure a certain strength, the bottle wall is generally thicker. Reagent bottle is divided into narrow mouth or wide mouth, clear or amber,and with stopper or without stopper. Among them, glass stopper, no matter small mouth, wide mouth, should have inside ground sand processing craft.
The specifications of reagent bottles are expressed in volume size, small to 30mL, 60mL, ranging from thousands to tens of thousands of ml.
Precautions for use:
(1)
when the reagent bottle is not used, you need to slip the paper between
the bottle stopper and the bottle mouth to prevent adhesion. As
mentioned above, none of the reagent bottles can be used for heating.
(2)
according to holding the physical and chemical properties of the
reagents needed reagent bottles of the general principle is: dress up
solid reagent selection jar, holding liquid reagent - choose fine mouth
bottle, all see light is easy to break down, or metamorphic reagent to
choose brown bottle, holding low boiling point volatile reagent chooses a
frosted glass reagent bottles, holding a alkaline reagent selection
with a rubber plug reagent bottles, and so on. If the reagent has the
above multiple physical and chemical indexes, the appropriate reagent
bottle can be selected according to the above principles.
(3) some special reagents, such as hydrofluoric acid, are not available in any glass reagent bottles and are used in plastic bottles.
