The vial is a relatively small glass tube or vial, usually with a vial cap. Bottle bottoms are generally flat, rather than having a spherical bottom like a test tube. When choosing a vial, customers should mainly choose from several aspects, such as material, color, volume, diameter, bottle mouth type, and whether to take writing or not.
Material and color Vials are usually made of glass. They can be colorless or colored, clear or amber. For example, the common brown reagent vial is mainly used to avoid light.
