2026
All animal procedures described here must be conducted in accordance with institutional animal ethics guidelines and approved by IACUC. All procedures must follow the principles of the 3Rs—Replacement, Reduction, and Refinement—and must be performed by trained personnel. Environmental enrichment involves objects and practices that encourage natural behaviors, improve psychological well-being, and promote better welfare in laboratory rodents. Environmental enrichment should be tailored to the...

Source: Laboratories of Margaret Workman and Kimberly Frye - Depaul University Elemental Analysis is a method used to determine elemental composition of a material. In environmental samples such as soils, scientists are particularly interested in the amounts of two ecologically important elements, nitrogen and carbon. Elemental analysis by the flash combustion technique works by oxidizing the sample with a catalyst through combustion in a high-temperature chamber. The products of combustion are...
FAQs
Environmental chamber control depends on a feedback loop rather than a single fixed setting. Sensors monitor temperature, humidity, light, and atmospheric composition, while control systems compare conditions with programmed targets. Heating, cooling, humidification, ventilation, or lighting then adjust the enclosure. This continual correction helps maintain defined conditions during biological experiments.
Separating variables allows researchers to examine how a selected condition affects plant growth, insect development, microbial activity, or organismal stress responses without allowing uncontrolled environmental changes to obscure the result. The approach supports clearer interpretation because each manipulated factor can be related to observed biological performance under defined conditions.
Programmed settings establish repeatable physical conditions across an experiment, while continuous monitoring helps keep those conditions aligned with targets. This consistency makes it easier to compare biological responses among treatments or experimental runs. It is especially useful when researchers need to test defined climate scenarios or evaluate performance under controlled stress.
Atmospheric composition provides another controllable part of the environment, allowing researchers to manipulate more than thermal or moisture conditions alone. When combined with controlled light, temperature, or humidity, it can help reveal how organisms respond to defined environmental scenarios. This broader control is relevant to studies of climate effects and biological stress.
Researchers first establish the environmental conditions relevant to the question, then use the chamber’s programmed controls and sensors to maintain them. The biological material, such as plants, insects, microbes, or other organisms, is observed under those conditions. Researchers can then relate growth, development, activity, or stress responses to the defined environment.
They would choose an Environmental Chamber when the study requires repeatable conditions or deliberate testing of environmental stress. The system is useful for examining climate effects, optimizing cultivation, and testing biological performance while reducing variation from uncontrolled surroundings. Applications span plant growth, insect development, microbial activity, and organismal responses.
