In the production process of glass drip bottle, not only should the pharmaceutical low borosilicate transparent glass tube within the tolerance range of industry regulations, but also to achieve the requirements of no burr, no bubble, no mold spot. Glass glass drip bottle manufacturers strictly control the size and shape of the   glass glass drip bottle   during the production process, and clean and pack the glass glass drip bottle after the production is completed.     1. Different classification Glass dropper bottle: divided into fat belly glass dropper bottle and common glass dropper bottle. It consists of a rubber nipple and a pointed glass tube. Rubber-tipped glass dropper bottle: there are several forms of straight, straight with cushion ball and curved with cushion ball. The specifications of the plastic-tipped glass drip bottle are indicated by the length of the tube, commonly used are 90mm and 100mm. Plastic-tipped glass dropper bottle 0.05ml per drop. 2. Di...

Butyl rubber stoppers   are airtight, heat resistant, acid and alkali resistant, and have a high level of internal cleanliness. It quickly replaced natural rubber in the production of pharmaceutical stoppers. Butyl rubber is a synthetic rubber made of isobutylene and a small amount of isoprene (<3%) polymerized by ultra-low temperature (95℃), its unique chemical stability, excellent sealing properties ensure the quality of drugs, drug safety, while reducing the production of natural rubber stoppers required wax process, pad and tape fiber film process. Butyl rubber stoppers are far superior to natural rubber stoppers in terms of product specification, production level, application function and product quality.     Butyl rubber stopper intrinsic cleanliness, chemical stability, air tightness, biological function is very good, but due to the mixed formula and the added raw material concentration gradient contact, some molecules are highly active, drug encapsulation, drug...

There are two common halogenated butyl rubbers used for manufacturing Pharmaceutical Stoppers, including chlorobutyl rubber and bromobutyl rubber.  Rubber components are essential for the safe containment and delivery of parenteral drug products. Many rubber formulations used in the pharmaceutical industry are based on halobutyl rubbers. Halobutyl rubbers, typically  bromobutyl or chlorobutyl , are made by the halogenation of butyl rubber, which is a copolymer of isobutylene and isoprene (to a smaller extent). Key features of halobutyl rubbers that make them suitable for the pharmaceutical industry are that they typically have lower levels of extractables compared to other rubbers, and they have excellent resistance to permeation by water and oxygen.     The question is often raised as to when to choose a bromobutyl- versus a chlorobutyl-based component. The answer is - it depends. They are comparable in terms of permeability for oxygen and water. Primary differences...
