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...

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 sy...

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: ...

  Each medicinal glass bottle is annealed, the role of annealing is to eliminate or reduce the thermal stress of the glass bottle to the allowable value of the heat treatment process, after annealing, it is not easy to rest in extreme cold and heat. Annealing of glass bottles is to eliminate and reduce the stress. Glass bottles undergo drastic and uneven temperature changes during the manufacturing process, which leads to thermal stresses in the glass product. This thermal stress can reduce the strength and thermal stability of the glass bottle, and even lead to self-cracking of the glass bottle.     Pharmaceutical glass bottles  Stress in glass is generally divided into three categories, namely thermal stress, mechanical stress and structural stress.   1. thermal stress: glass products due to temperature differences in the stress called thermal stress, according to its existence can be divided into temporary stress and permanent stress. (1) temporary stress: th...

In slurry pumps, the impeller and the inside of the pump casing are always exposed to the slurry and must therefore be protected against wear accordingly. "The choice of material for the impeller and pump casing is as important as the choice of the pump itself!"     Three different conditions that generate wear in slurry pumps. Abrasion, erosion, corrosion 1.Wear Wear is divided into three main types. In slurry pumps, we have mainly abrasion and low stress wear. The rate of wear depends on particle size and hardness. Wear in  slurry pumps  occurs in only two areas. a. Between the impeller and the fixed inlet. b. Between the shaft sleeve and the fixed packing. 2. Erosion This is the main wear of the slurry pump. The reason is that the particles in the slurry hit the material surface at different angles. The way the pump is operated can seriously affect erosion wear. In general, erosion wear is lowest at BEP flow rates and increases as the flow rate increases and decre...
