Rubber vial stopper

Rubber vial stopper is located on almost every glass or plastic vessel or bottle, which is used to store medications or other similar substances, which must be protected from the negative effects of oxygen and other external factors. Although there is no specific regulation or law that obliges manufacturers of drugs and chemicals to use rubber vial stoppers to close vials, most of them implement rubber vial stoppers, as nothing can protect substances from moisture, for example, as good as this type of rubber stopper can.

Whether pharmacotherapy is in the form of capsules, liquids or powders, it is equally important to protect it against things that can change the chemical composition of medications. In some cases, medications will only lose their effect, and in some cases they can become dangerous. It is therefore advisable to use a rubber vial stopper to create a hermetically sealed environment where the drugs will be able to remain in their unchanged form for a long time.

It is important to know the diameter as well as the depth of the part of the vial where the rubber vial stopper will be located. It is necessary that the size of the stopper is such that it barely fits in the vial, in order to prevent any passage of oxygen, liquid or any other substance that should not come into prolonged contact with your medication. You can order any size from us, so you don’t have to worry even if the vial is some non-specific size.

Choose the color of rubber vial stopper if you have numerous vials with different medications. This will make it much easier for you to tell where each medication is, without having to label the vial in any other way or remember which form the medicine takes. It can also be potentially dangerous if many drugs look similar.
