Oxygen and Carbon Dioxide in a Biology Research Lab
As a biology researcher or owner of a lab, you know very well the importance of instrument-grade and ultra-high-purity gases. To that end, the importance of oxygen (O2) and carbon dioxide (CO2) cannot be overemphasized. Finding uses in various laboratory applications such as cell culture, microbial culture, and pH control, these gases are among the most crucial and widely used in any biology research lab.
Usually procured in gas cylinders from experienced suppliers of specialized gases like nexAir, the gas levels are monitored to ensure they are within the safe ranges for the organisms/specimen being studied.
Multi-Faceted Uses of O2 and CO2 in Laboratory Settings
As the fundamental element for cellular respiration, O2 is used in cell cultivation. The gas is supplied to cell cultivation via an incubator as well as in tissue and microbial culture. With techniques like respirometry to measure the oxygen consumption rate in cells or tissues and the study of their metabolic processes, oxygen is used to learn more about cellular respiration. Laboratories also utilize oxygen to produce materials such as hydrogen peroxide and sterilization to keep lab equipment and the immediate environment free from contamination.
CO2, on the other hand, is a key component in photosynthesis studies wherein, for example, researchers measure the gas uptake of plants or algae in different light conditions. CO2 is also bubbled through solutions to lower its pH. In addition, carbon dioxide is the primary mobile phase for supercritical fluid chromatography.
Dry Ice Novelty of CO2
Dry ice is another novel application of CO2. It is made by compressing and cooling liquid CO2, to directly change it to a solid state. Dry ice plays a pivotal role in the preservation, experimentation, storage, preservation, and shipment of biological specimens. It is commonly used in pharmaceutical labs, genetic engineering, and DNA research.
Suppliers make it available in blocks or pellets which are stored and transported in insulated containers to prevent it from sublimating. Unlike regular ice, dry ice changes directly to gas while emitting a white cloud of CO2.
