The air in the incubator was kept at 37 degrees Celsius, the same temperature as the human body, and the incubator maintained the atmospheric carbon dioxide and nitrogen levels necessary to promote cell growth. At this time, incubators also began to be used in genetic engineering. Scientists could create biologically essential proteins, such as ...
They need to be kept at body temperature (37 °C) in an incubator. [1] These conditions vary for each cell type, but generally consist of a suitable vessel with a substrate or rich medium that supplies the essential nutrients ( amino acids , carbohydrates , vitamins , minerals ), growth factors , hormones , and gases ( CO 2 , O 2 ), and ...
A temperature-controlled shaker, as used in biochemistry work. A shaker is a piece of laboratory equipment used to mix, blend, or agitate substances in a tube or flask by shaking them. It is mainly used in the fields of chemistry and biology. A shaker contains an oscillating board that is used to place the flasks, beakers, or test tubes.
An Orsat gas analyser or Orsat apparatus is a piece of laboratory equipment used to analyse a gas sample (typically fossil fuel flue gas) for its oxygen, carbon monoxide and carbon dioxide content. Although largely replaced by instrumental techniques, the Orsat remains a reliable method of measurement and is relatively simple to use. [1]
Additionally, using Durham tubes to provide evidence of fermentation may not be able to detect slow- or weakly-fermenting organisms when the resultant carbon dioxide diffuses back into the solution as quickly as it is formed, [4] so a negative test using Durham tubes does not indicate decisive physiological significance.
A FACE experiment began at Duke University in June 1994. The Blackwood Division of the Duke Forest contains the Forest-Atmosphere Carbon Transfer and Storage facility. This consists of four free-air CO 2 enrichment plots which provide higher levels of atmospheric CO 2 concentration and four plots that provide ambient CO 2 control. [ 5 ]
The most common principles for CO 2 sensors are infrared gas sensors and chemical gas sensors. Measuring carbon dioxide is important in monitoring indoor air quality, [1] the function of the lungs in the form of a capnograph device, and many industrial processes.
A laminar flow cabinet blows unfiltered exhaust air towards the worker and is not safe for work with pathogenic agents, [2]: 13 [3] while a fume hood maintains negative pressure with constant exhaust to protect the user, but does not protect the work materials from contamination by the surrounding environment.
