For GL45 Reagent Bottle, do you Really Know?

Jul. 7th, 2022

The Reagent Bottles, also known as media bottles, are used to store chemicals in liquid or powder form. They are generally made up of glass or plastic. The first Reagent Bottles were manufactured by DURAN in the year 1972 and they are the pioneers of it.

The reagent bottles were primarily designed to store reagents but with the passage of time and its improved design, various other chemicals can be stored in these bottles. A reagent is a compound that when added to a system, causes a chemical reaction. The bottle has a narrow mouth opening on the top with a pouring ring. The sloping shoulders of the reagent bottles help the liquid to flow smoothly.
