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 which 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 helps the liquid to flow smoothly.
Narrow Mouth - GL 45 (available in Clear Glass and Amber). It comes with a storing capacity of upto 2000 ml. These are round in shape and are generally used to store liquid media and compounds like reagents.
Wide Mouth - GL 80 (available in Clear Glass only). It comes with a capacity of upto 2000 ml. These bottles are available in both round and square shapes. Granules and paste-like substances are stored in these bottles. The square shaped bottles are an ideal for short term storage of a media.
Do not tighten the caps immediately after autoclaving.
Reagent bottles larger than 2 litres should not be used under vacuum pressure as they may cause breakage.
