An introduction to the types of ampoules


  Ampoules are sealable pharmaceutical glass bottles, which can be divided into colour ring ampoules and colour dot ampoules. They are often used to store injectable medicines and vaccines, serums, etc.

安(ān)瓿瓶

  Ampoules are made from glass tubes fired and are widely used for high purity chemicals where injectables and air isolation are required. The head of the ampoule is ignited with a flame for minutes in order to isolate the air. The neck of the bottle is marked with a colour ring and colour dot. Applying pressure can cause the neck of the bottle to fracture, thus advancing the drug.

  Using ampoules: Ampoules are small glass containers for growing medicinal solutions. The capacity is usually 1 ~ 25 ml. They are often used for medicinal solutions. Before opening, use an abrasive wheel to remove scratches and sterilise the neck of the bottle from the neck, pull the head upwards so that all the medicinal solution flows into the bottle, and then simply break the neck of the bottle. Folding ampoules have the manufacturer's pre-cut part marked on the nipple, and it is sufficient to break the nipple directly in this direction.

  Ampoules are known as glass injection bottles, glass antibiotic bottles etc. They are often used as bottles for antibiotics such as penicillin, hence the names glass penicillin bottles and penicillin glass bottles, and are also used as lyophilised products. Also known as freeze-dried glass bottles, split shot bottles and water shot bottles.

  In recent years, with the improvement of the overall level of pharmaceutical packaging material manufacturers in China, the scale of enterprises, production technology, management level and product quality have all developed significantly. There are many types of ampoules, let me explain them one by one.

  1、Material classification

  They are mainly divided into neutral borosilicate glass amplifiers and low borosilicate glass amplifiers. This is distinguished by the boron oxide content of the glass. The boron oxide content of neutral silica glass ampoule is 8% ~ 12%, which is chemically stable, but the price is high in the domestic mayor/market, and only 5% ~ 8% boron oxide content is popular and inexpensive in some products, so the domestic mayor/market coverage is high.

  2、Classification from product shape

  It can be classified into four types: B type, C type, D type and E type, pharmaceutical companies can choose the corresponding bottle type according to the requirements and characteristics of the production line. B and C type have relatively low production environment requirements, while D and E type ampoules do not need to be cleaned by customers, and the sealed ampoules will be opened directly on the Guanfeng line, which has higher hygiene requirements, and only one or two enterprises can produce them in China at present.

  3. Classification in simple analysis methods

  It can be classified into three categories: dot etching analysis, colour ring analysis and circular cut analysis. These three simple analysis methods are more commonly used among China are the first two, but with the development of differentiation and personalization, the colour bell (including decorative ring) of Rishi Anqiu is also gradually accepted by domestic customers. In addition, international pharmaceutical companies have adopted the new ring-cut engraving method, but this method has high requirements on the size of glass tube specifications, bottle process and charging equipment. In addition, the colour of ampoules is mostly colourless. Brown glass ampoules are mostly used for light-sensitive drugs, but brown ampoules contain iron oxide, which can decompose certain active ingredients of drugs and are not widely used at one time.
