Bung
A stopper, bung, or cork is a cylindrical or conical closure used to seal a container, such as a bottle, tube, or barrel. Description Unlike a lid or bottle cap, which encloses a container from the outside without displacing the inner volume, a bung is partially or wholly inserted inside the container to act as a seal. A bung can be defined as "a plug or closure used to close an opening in a drum or barrel. It is called a plug when referring to a steel drum closure." A glass stopper is often called a "ground glass joint" (or "joint taper"), and a cork stopper is called simply a "cork". Stoppers used for wine bottles are referred to as "corks", even when made from another material. A common every-day example of a stopper is the cork of a wine bottle. When used to seal the bungholes of barrels, the stopper is called a bung. Other bungs, particularly those used in chemical barrels, may be made of metal and be screwed into place via threading.

Bunghole
A bunghole is a hole bored in a liquid-tight barrel to remove contents. The hole is capped with a cork or cork-like stopper called a '' bung''. Acceptable usage includes other access points that may be capped with alternate materials providing an air- or water-tight access to other vessels. For example, a bunghole on a combustion chamber can be used to remove slag or add coal. Bungholes can also be utilized to insert and remove sensing probes or equipment like mixers to agitate the contents within a vessel. History and usage Bungholes were first used on wooden barrels, and were typically bored by the purchaser of the barrel using a brace and bit. Bungholes can be bored in either head (end) of a barrel or in one of the staves (side). With the bung removed, a tapered faucet can be attached to aid with dispensing. When barrels full of a commodity were shipped, the recipient would often bore new bungholes of the most suitable size and placement rather than remove the existing bu ...

Closure (container)
A closure is a device used to close or seal a container such as a bottle, Jug (container), jug, jar, Tube (container), tube, or can (other)#Container, can. A closure may be a cap, cover, Lid (container), lid, plug, liner, or the like. The part of the container to which the closure is applied is called the finish. Other types of containers such as boxes and drum (container), drums may also have closures but are not discussed in this article. Many containers and packages require a means of closing, which can be a separate device or seal or sometimes an integral latch or lock. Purpose of closures The closure is often the most critical part of a package, and must fulfill all of the food packaging#Functions, basic functions of packaging in addition to being easy to open and (if applicable) reclose. Depending on the contents and container, closures have several functions: * Keep the container closed and the contents contained for the specified shelf life until time of open ...

Barrel (storage)
A barrel or cask is a hollow cylindrical container with a bulging center, longer than it is wide. They are traditionally made of wooden staves and bound by wooden or metal hoops. The word vat is often used for large containers for liquids, usually alcoholic beverages; a small barrel or cask is known as a keg. Barrels have a variety of uses, including storage of liquids such as water, oil, and alcohol. They are also employed to hold maturing beverages such as wine, cognac, armagnac, sherry, port, whiskey, beer, arrack, and sake. Other commodities once stored in wooden casks include gunpowder, meat, fish, paint, honey, nails, and tallow. Modern wooden barrels for wine-making are made of English oak (''Quercus robur''), white oak (''Quercus petraea''), American white oak (''Quercus alba''), more exotic is mizunara oak ('' Quercus crispula''), and recently Oregon oak ('' Quercus garryana'') has been used. Someone who makes traditional wooden barrels is called a coop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ground Glass Stopper
Ground glass joints are used in laboratories to quickly and easily fit leak-tight apparatus together from interchangeable commonly available parts. For example, a round bottom flask, Liebig condenser, and oil bubbler with ground glass joints may be rapidly fitted together to reflux a reaction mixture. This is a large improvement compared with older methods of custom-made glassware, which was time-consuming and expensive, or the use of less chemical resistant and heat resistant corks or rubber bungs and glass tubes as joints, which took time to prepare as well. One of the glassware items to be joined would have an ''inner'' (or male) ''joint'' with the ground glass surface facing outward and the other would have an ''outer'' (or female) ''joint'' of a correspondingly fitting taper with the ground glass surface facing inward. To connect the hollow inner spaces of the glassware components, ground glass joints are hollow on the inside and open at the ends, except for stoppers. ...

Jug With Cork Stopper
A jug is a type of container commonly used to hold and serve liquids, but not normally to drink from directly. It has an opening, sometimes narrow, from which to pour or drink, and has a handle, and usually a pouring lip. Jugs throughout history have been made of metal, ceramic, or glass, and plastic is now common. In British English, jugs are pouring vessels for holding drinkable liquids, whether beer, water or soft drinks. In North American English these table jugs are usually called Pitcher (container), pitchers. Ewer is an older word for jugs or pitchers, and there are several others, such as flagon. Several other types of containers are also called jugs, depending on locale, tradition, and personal preference. Some types of bottles can be called jugs, particularly if the container has a narrow mouth and has a handle. Closures such as Bung, stoppers or screw caps are common for these retail packages. Etymology The word jug is first recorded in the late 15th century a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Submarine Telegraph Cable
A submarine communications cable is a cable laid on the seabed between land-based stations to carry telecommunication signals across stretches of ocean and sea. The first submarine communications cables were laid beginning in the 1850s and carried telegraphy traffic, establishing the first instant telecommunications links between continents, such as the first transatlantic telegraph cable which became operational on 16 August 1858. Submarine cables first connected all the world's continents (except Antarctica) when Java was connected to Darwin, Northern Territory, Australia, in 1871 in anticipation of the completion of the Australian Overland Telegraph Line in 1872 connecting to Adelaide, South Australia and thence to the rest of Australia. Subsequent generations of cables carried telephone traffic, then data communications traffic. These early cables used copper wires in their cores, but modern cables use optical fiber technology to carry digital data, which includes telep ...

Cork Borer
A cork borer, often used in a chemistry or biology laboratory, is a metal tool for cutting a hole in a cork or rubber stopper to insert glass tubing. Cork borers usually come in a set of nested sizes along with a solid pin for pushing the removed cork (or rubber) out of the borer. The individual borer is a hollow tube, tapered at the edge, generally with some kind of handle at the other end. A separate device is a ''cork borer sharpener'' used to hone the cutting edge to more easily slice the cork. Cork borers are also used to take samples from living trees, for tree ring analysis (dendrochronology), and for taking samples for experiments when a constant diameter is required, e.g. When testing the water potential of a potato, a cork borer is used to maintain a constant surface area. A cork borer is also used to punch holes on an agar plate and to perform well diffusion assays in microbiology to study bioactivity In pharmacology, biological activity or pharmacological activi ...

Laboratory Equipment
A laboratory (; ; colloquially lab) is a facility that provides controlled conditions in which scientific or technological research, experiments, and measurement may be performed. Laboratories are found in a variety of settings such as schools, universities, privately owned research institutions, corporate research and testing facilities, government regulatory and forensic investigation centers, physicians' offices, clinics, hospitals, regional and national referral centers, and even occasionally personal residences. Overview The organisation and contents of laboratories are determined by the differing requirements of the specialists working within. A physics laboratory might contain a particle accelerator or vacuum chamber, while a metallurgy laboratory could have apparatus for casting or refining metals or for testing their strength. A chemist or biologist might use a wet laboratory, while a psychologist's laboratory might be a room with one-way mirrors and hidden cameras in ...

Thermoplastic
A thermoplastic, or thermosoftening plastic, is any plastic polymer material that becomes pliable or moldable at a certain elevated temperature and solidifies upon cooling. Most thermoplastics have a high molecular weight. The polymer chains associate by intermolecular forces, which weaken rapidly with increased temperature, yielding a viscous liquid. In this state, thermoplastics may be reshaped, and are typically used to produce parts by various polymer processing techniques such as injection molding, compression molding, calendering, and extrusion. Thermoplastics differ from thermosetting polymers (or "thermosets"), which form irreversible chemical bonds during the curing process. Thermosets do not melt when heated, but typically decompose and do not reform upon cooling. Above its glass transition temperature and below its melting point, the physical properties of a thermoplastic change drastically without an associated phase change. Some thermoplastics do not fully ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
