Description

Reagent bottle

Technical Field

The invention relates to a container for containing a reagent, in particular to a reagent bottle.

Background

The reagent bottle is the bottle that is used for holding chemical reagent, divide into glass and plastics according to the material, can divide into wide-necked bottle and narrow-necked bottle according to the size, can divide into solid and liquid reagent bottle according to holding the material, and the wide-necked bottle holds the solid, and the narrow-necked bottle holds liquid. The inside dull polish design that is of the bottleneck keeps sealed, prevents that reagent from leaking outward.

In the process of opening the cap, an experimenter firstly unscrews the outer cap and then can pull out the inner cap.
