A Bunsen burner, named after Robert Bunsen, is a kind of ambient air gas burner used as laboratory equipment; it produces a single open gas flame, and is used for heating, sterilization, and combustion.
A test tube, also known as a culture tube or sample tube, is a common piece of laboratory glassware consisting of a finger-like length of glass or clear plastic tubing, open at the top and closed at the bottom.
Neil Bartlett was a British chemist who specialized in fluorine and compounds containing fluorine, and became famous for creating the first noble gas compounds. He taught chemistry at the University of British Columbia and the University of California, Berkeley.
Prof Friedrich Stromeyer FRS(For) FRSE was a German chemist. He was the discoverer of cadmium.
Peter Waage was a Norwegian chemist and professor of chemistry at the University of Kristiania. Along with his brother-in-law Cato Maximilian Guldberg, he co-discovered and developed the law of mass action between 1864 and 1879.
A flame test is relatively quick test for the presence of some elements in a sample. The technique is archaic and of questionable reliability, but once was a component of qualitative inorganic analysis. The phenomenon is related to pyrotechnics and atomic emission spectroscopy. The color of the flames is understood through the principles of atomic electron transition and photoemission, where varying elements require distinct energy levels (photons) for electron transitions.
Fisher Scientific International, Inc. was a laboratory supply and biotechnology company that provided products and services to the global scientific research and clinical laboratory markets until its merger with Thermo Electron in 2006, after which it became Thermo Fisher Scientific. The company offered products and services to over 350,000 customers located in approximately 150 countries including pharmaceutical and biotechnology companies, secondary and higher education institutions, hospitals and medical research institutions, and quality control, process control and research and development laboratories.
A gas burner is a device that produces a non-controlled flame by mixing a fuel gas such as acetylene, natural gas, or propane with an oxidizer such as the ambient air or supplied oxygen, and allowing for ignition and combustion.
A heated bath is used in the laboratory to allow a chemical reaction to occur at an elevated temperature.
Nicolae Teclu ; was a Romanian chemist, who gave his name to the worldwide-used "Teclu burner". He studied engineering and architecture, and then chemistry, continuing his career by becoming professor for general and analytical chemistry in Vienna. He also contributed substantially to the worldwide development of chemistry.
Wire gauze or wire mesh is a gauze woven of metal wire, or very fine, gauze-like wire netting. Wire gauze is placed on the support ring that is attached to the retort stand between a burner and glassware, or is placed on a tripod to support beakers, flasks, or other glassware to protect it during heating. Glassware should not be heated directly by the flame of a Bunsen or other gas burner; wire gauze diffuses the heat and protects the glassware. Glassware has to be flat-bottomed if rested on the wire gauze.
Chevron Science Center is a landmark academic building at 219 Parkman Avenue in Pittsburgh, Pennsylvania, United States on the campus of the University of Pittsburgh. The 15-story facility, completed in 1974, was designed by Kuhn, Newcomer & Valentour and houses the university's chemistry department. A three-story addition above Ashe Auditorium was completed in 2011.
Dr. Bunsen Honeydew is a Muppet character from the sketch comedy television series The Muppet Show, created and performed by Dave Goelz. He is a bald, yellow-green skinned, bespectacled, lab-coated scientist who presented periodic science segments from "Muppet Labs, where the future is being made today." The character has no eyes, only completely transparent, lensless glasses, giving the appearance of a stereotypical absent-minded intellectual. Bunsen's experiments usually cause great harm to his very nervous and long-suffering assistant Beaker, a nearly mute Muppet with a shock of reddish hair.
Reflux is a technique involving the condensation of vapors and the return of this condensate to the system from which it originated. It is used in industrial and laboratory distillations. It is also used in chemistry to supply energy to reactions over a long period of time.
A Meker–Fisher burner, or Meker burner, is an ambient air laboratory burner that produces multiple open gas flames, used for heating, sterilization, and combustion. It is used when laboratory work requires a hotter flame than attainable using a Bunsen burner, or used when a larger-diameter flame is desired, such as with an inoculation loop or in some glassblowing operations. The burner was introduced by French chemist Georges Méker in an article published in 1905.
The Teclu burner is an ambient air laboratory gas burner, that was created by Romanian chemist Nicolae Teclu in 1882. The burner is most commonly used to heat substances in a laboratory, can be used for sterilisation and sometimes it is used for soldering or glasswork. It is commonly made from brass or iron.The burner physically consists of a round base, a tube connected to it providing the gas to the flame and a vertical metal tube that directs the flame upwards. The tube has a conical shape closer to the base.
Robert Wilhelm Eberhard Bunsen was a German chemist. He investigated emission spectra of heated elements, and discovered caesium and rubidium with the physicist Gustav Kirchhoff. The Bunsen–Kirchhoff Award for spectroscopy is named after Bunsen and Kirchhoff.
A splint is a simple piece of equipment used in scientific laboratories. Splints are typically long, thin strips of wood, about 6 inches (15 cm) long and ¼ inch (6 mm) wide, and are consumable but inexpensive. They are typically used for tasks such as lighting bunsen burners, as the length of the splint allows a flame to be lit without risk to the user's hand, should the burner flare back. Another use for splints are chemical identification of various gases, and splints are also used to teach simple chemical principles in schools and homes.
An alcohol burner or spirit lamp is a piece of laboratory equipment used to produce an open flame. It can be made from brass, glass, stainless steel or aluminium.
A laboratory tripod is a three-legged platform used to support flasks and beakers. Tripods are usually made of stainless steel or aluminium and made light-weight for efficient portability within the lab. Often a wire gauze is placed on top of the tripod to provide a flat base for glassware. Tripods are generally tall enough for a bunsen burner to be placed underneath.
