Laboratory soil warming experiments usually employ two or more constant temperatures in multiple chambers. By presenting a sophisticated environmental chamber, we provide an accurate temperature control method to imitate the magnitude and amplitude of in situ soil temperature and improve the experimental design of soil incubation studies.

Decontamination for Laboratory Biosafety
0 Views •
2023
Robert M. Rioux and Zhifeng Chen, Pennsylvania State University, University Park, PA Decontamination is essential for laboratory biosafety, as the accumulation of microbial contamination in the laboratory can lead to the transmission of disease. The degree of decontamination can be classified as either disinfection or sterilization. Disinfection aims to eliminate all pathogenic microorganisms, with the exception of bacterial spores on lab surfaces or equipment. Sterilization, on the other hand,...

Measuring Mass in the Laboratory

The analytical balance is the common piece of equipment in the scientific laboratory. These highly precise instruments can measure down to ten thousandths or even hundred thousandths of a gram. The triple beam balance is a type of scale that uses counterweights on a three rider beams to counterbalance the sample in the pan. On the other hand, modern analytical balances use a complex system of electronic sensors to accurately mass a substance. The analytical balance is so sensitive that it...

Responding for food or drug-paired cues increases over the course of a period of abstinence and this may relate to an increased susceptibility to relapse behaviors. Here we detail a procedure for evaluating this "incubation of craving" in rats that have self-administered sucrose.
FAQs
Changing one or more defined factors, such as temperature, oxygen availability, moisture, light, or substrate supply, allows researchers to observe how biological, chemical, or physical responses change. Measurements of microbial activity, nutrient transformations, gas production, or contaminant breakdown can then be linked to those conditions. This helps separate interacting processes that are difficult to distinguish in soil, sediment, water, or waste systems.
Treatments expose environmental samples to selected conditions, while controls provide a comparison for interpreting the resulting changes. Comparing them helps determine whether differences in microbial activity, nutrient transformation, gas production, or contaminant breakdown are associated with the tested condition rather than with changes occurring without that treatment. This comparison strengthens interpretation of cause and effect in controlled environmental studies.
Oxygen availability is one of the environmental factors researchers can regulate to examine how conditions influence biological and chemical activity. Comparing samples under different oxygen conditions can reveal shifts in processes such as nutrient transformations, gas production, or contaminant breakdown. The resulting contrasts help identify how environmental conditions shape system behavior and provide evidence useful for interpreting broader ecosystem function.
Researchers place soil, sediment, water, or waste samples under defined experimental conditions, regulate selected factors, and monitor changes over time. They typically establish treatments and controls, maintain variables such as temperature, oxygen availability, moisture, light, or substrate supply, and measure responses including microbial activity, nutrient transformations, gas production, or contaminant breakdown. Results are then compared across conditions.
The design may control temperature, oxygen availability, moisture, light, and substrate supply, depending on the environmental process under investigation. Researchers can monitor microbial activity, nutrient transformations, gas production, and contaminant breakdown as outcomes. Selecting conditions and measurements that match the question allows the experiment to connect a specific environmental influence with a measurable biological, chemical, or physical response.
These experiments are useful when researchers need to isolate processes that are difficult to observe directly in soil, sediment, water, or waste systems. They support studies of pollution, climate change, and resource management by showing how conditions influence ecosystem function. Results can also inform biogeochemical modeling, where measured transformations and rates help represent environmental processes under defined scenarios.
