One size does not fit all. This goes for rubber stoppers used in various industries. The  rubber stoppers  are made of different shapes and diameters to give the perfect fit. Rubber plugs are used to stop spillage and seal the containers so it is important the right type of rubber stopper is used. Therefore, in this article, I will tell you what rubber stoppers are and nine different types of rubber stoppers. So, let’s find out.     What Is a Rubber Stopper? A rubber stopper is a small, tapered plug used to seal the openings of test tubes, flasks and other laboratory glassware. Stoppers made of cork are also available for this purpose. However, rubber stoppers are preferable for applications that require a tighter seal or a greater degree of chemical resistance.   Purpose The primary purpose of a  rubber stopper  is to prevent a gas or liquid from escaping its container during a scientific experiment. Rubber stoppers can also prevent the contamina...

The types of rubber stoppers that exist in the market reflect the needs of manufacturers for various items. First, it can be said that these components are characterized by their versatility, making them prominent in the output produced. Therefore, they can be integrated into different types of structures and become an integral part. Types of rubber stoppers 1.Bromobutyl rubber stopper Bromobutyl rubber stopper   mainly used for glass vials and large infusion bottles, with aluminum caps or aluminum plastic (flip cap) caps. Advantages of bromobutyl rubber stoppers: a. High cleanliness standard. Production of less than 100,000 clean area, b. Perfect service system, with professional technicians, to provide customers with supporting and personalized services at any time; c. Supply well-known pharmaceutical companies at home and abroad. 2.Polyethylene Stopper/Discs Sealing for plastic infusion containers Polyethylene Stopper also named: flask stopper, flask stoppers Polyethylene stopp...

Medicinal rubber stoppers can be divided into natural rubber stoppers and butyl rubber stoppers according to the rubber materials used. Natural rubber stoppers use natural rubber as the main component, which is easy to breed mold, has poor sealing performance, and is prone to chemical reactions with drugs. Butyl rubber stopper is mainly composed of halogenated butyl rubber, which has good air tightness, chemical stability and biological safety, and is currently the mainstream product in the field of medicinal rubber stoppers. The current domestic bromobutyl formula Generally, sulfur is used for vulcanization, which has high efficiency and low cost. However, the activity of chlorinated butyl group is relatively low, the choice of vulcanization system is slightly limited, and the production process and technical requirements are relatively strict, and the difficulty is relatively large. In the early days, phenolic resin, stearic acid and zinc oxide were commonly used as vulcanization sys...

Butyl rubber is synthesized from petrochemicals and is a copolymer of isobutylene and a small amount of isoprene. Subsequent halogenation produces halogenated butyl rubber—usually bromobutyl or chlorobutyl. What is bromobutyl rubber? Bromobutyl rubber: is a terpolymer of isobutylene, isoprene, and brominated isoprene. Bromobutyl rubber   (BIIR) is an isobutylene-isoprene copolymer elastomer containing reactive bromine. Because bromobutyl rubber has a substantially saturated backbone of butyl rubber, it has many performance characteristics of butyl polymers, such as higher physical strength, better vibration damping properties, low permeability, aging resistance and Weather-resistant. The invention and use of the halobutyl rubber innerliner has in many ways enabled the modern radial tire. The use of these polymers in tire innerliner compounds can improve pressure holding properties, improve the adhesion between the innerliner and the carcass, and improve tire durability. Advantage:...

Heparin Caps are composed of cap, rubber plug, and lock conical connector. ◬This product is used as a fitting connector on the pipeline of infusion (transfusion) sets to inject medicinal liquid into the pipeline, and can also be used to inject heparin solution connected with the IV catheter for anticoagulation. ◬Puncture repeatedly 30 times without falling chips. ◬Withstand 20Kpa pressure for 30s without leakage. ◬Non-latex material is safe and non-toxic. ◬Transparent appearance is easy to observe.   Specification: Color:yellow/transparence Component: 1.base 2.plug Material 1.ABS   2.Nature rubber/Compound rubber Function: use with canula for clinical blood transfusion Use method: 1. peel the packing and take out the product 2. rotate and connect with lock jointor and circular jointor of needle base of canula  3.draw medical liquid you want then inject into herparin cap through  plug of herparin cap Expiry date: 3 years .   Form of packing: 1pcs/pvc+bl...

Rubber stoppers   are ideal for plugging joints or holes in laboratory glassware and creating a liquid-tight seal. Rubber bungs are often used with glass containers such as test tubes, flasks, jugs, and many other pieces of standard lab equipment. We carry stoppers both with and without pre-drilled holes, in a wide range of the most common sizes. Practically speaking, there are around 16 different sizes of standard laboratory rubber stopper, but we’ve narrowed down the selection somewhat to only those most practical for commercial and hobbyist use. Available with and without holes. There are many situations in which having pre-drilled holes can be useful. For example, let’s say you need to hold a thermometer precisely in the center of your container while still maintaining an air-tight seal. Having a pre-drilled hole in the center will ensure proper, consistent alignment. Buchner Funnels (for filtering) can also benefit from this type of stopper. If the holes are too small, they ca...
