QI need further information about the reagent containers.
There are different shapes, sizes, colors and materials used for reagents containers depending on the reagent type to avoid contamination by external influences. This way FUJIFILM Wako can provide safety and best quality for its products.
|Glass bottle||Mainly used for common liquid reagents. Light sensitive reagents are often stored within brown bottles to protect them from outside lights.
[Material] Hard glass
[Advantages] Very airtight, chemically stable, insensitve to impacts and transparent to see the contained substance.
[Disadvantages] Heavy, fragile, unsuitable for alkali
|Poly bottle||Mainly used for common powder reagents.
[Material] Polyehtylene, polypropylene, teflon
[Advantages] Lightweight compared to glass, hardly breakable.
[Disadvantages] Lower transparency, hardness and airtightness compared to glass. Additives which were used during the manufacturing process of the bottle may influence the reagents.
|Ampoule bottle||Used for smaller units of liquid reagents, highly reactive and highly volatile compounds.
[Advantages] Encapsulated in a container. Usable for fuming or air sensitive substances and liquids that may leak out offensive odors, as well as substances which are not allowed to be changed in their concentration during storage of standard solutions, etc..
[Disadvantages] Hard to handle, difficult top open. Because there is no lid, it has to be stored in a separate container once it is opened.
|Vial bottle / Injection bottle||Applicable for frequent usage of smaller units liquid or powedered reagents.
[Material] Small bottle sealed with a septum to take out small amounts from the inside with a syringe or a small bottle with a glass pippete integrated into the lid.
[Advantages] Easy to open and close. Simple handling. Septum prevents air intrusion and allows to easily extract small units with a syringe.
[Disadvantages] Loss of airthightness after opening. Lower airthightness due to septum.
Septum: A cover made of soft special rubber which seals the open bottle to prevent leakage of the reagent.
|Can||Used for large quantities orangic solvents, etc..
[Advantages] Good airtightness, less elution from the container walls, light and resistant.
[Disadvantages] Reagents which react with metals (e.g. acids or alkalis) can not be stored inside this container. Easily dent and hard to pour our the substances.
|Poly tank||Used for highly sensetive reagents like acids and alkalis.
[Material] Polyethylene, polypropylene, vinyl chloride resin, etc..
[Advantages] Excellent resistance against chemicals, light, hardly deformed.
[Disadvantages] Hard to pour out the substances. Additives which were used during the manufacturing process of the bottle may influence the reagents.
|Kit||Used when multiple reagents are needed simultaneously e.g. for biochemical experiments.
[Advantages] Just a small possibilty for adjustment errors since the kits don't need self-adjustments by the users. It is easy to use even with little routine, time efficient and resource-saving due to few adjustment errors.
[Disadvantages] It is not suitable to customize the kit components and/or compositions flexibly for your purposes.
Due to short expiry dates it is not possible to be stored for a long time.
Regarding airtightness of containers, JIS classifies into three categories: Well-closed container, tight container and hermetic container (ascending airthightness order).
Container that prevents intrustion of dust or solid contaminants.
E.g.: Cardboard, paper bag, polyethylene bag, etc..
Container that prevents intrusion of liquid or solid foreign matters or moistures as well as loss, deliquescence or evaporation.
E.g.: Glass bottle, polyethylene bottle, can, etc..
Container with an extremly low possibility of gas intrusion.
E.g.: Ampoule bottle, vial bottle (before opening) etc..
