A schema is a mental framework that helps individuals organize and interpret information. Schemata, formed from previous experiences, influence how we process new information: how we encode it, the inferences we make, and how we retrieve it. For instance, a schema for what a typical classroom looks like might include desks, a teacher's desk, a whiteboard, and students in such an environment. This expectation helps us quickly understand and navigate new classrooms without needing to analyze each...

2023
Preservation of laboratory samples, specimens, and reagents using extreme cold is routinely performed in biomedical research labs. This video will discuss some of the methods for keeping laboratory samples cold and will explain the correct cooling method to use for each experimental requirement. For example, cooling agents, such as ice and dry ice, are typically used when keeping samples cold during experiments. This video discusses the physical properties of the most commonly used cooling...

Rioux & Suprita Jharimune, Pennsylvania State University, University Park, PA Working with extreme temperatures, both high and low, is an integral part of many laboratory operations. For many, mentioning a laboratory instantly evokes the mental picture of a Bunsen burner. Bunsen burners and hot plates are used extensively in small and large operations in research laboratories and industries, thus making it necessary for all users to be aware of their safe handling...

Source: Robert M. Rioux & Taslima A. Zaman, Pennsylvania State University, University Park, PA While the use of various chemicals in experimental research is essential, it is also important to safely store and maintain them as a part of the Environmental, Health and Safety (EHS) program. The properties of chemicals and their reactivity vary broadly and if chemicals are not managed, stored, and labeled properly, they can have harmful or even destructive consequences such as toxic fume...
FAQs
Temperature control works by reducing the rates of enzyme activity, cellular metabolism, chemical reactions, and microbial growth rather than eliminating them. Consequently, a sample can still change when held outside its validated range or exposed to repeated warming and cooling. Stable conditions therefore support consistent sample quality and make results more reproducible across experiments.
Storage conditions must match the biological material and its intended use. Cells, tissues, reagents, and organisms may differ in how they tolerate cooling and later recovery, so a protocol should specify appropriate temperature, container, labeling, and handling requirements. These choices reduce avoidable damage and help preserve material that remains suitable for downstream biological analysis.
Monitoring shows whether the storage environment remains controlled, while careful handling limits unnecessary exposure during placement, removal, or transfer. Using both controls addresses different risks: monitoring supports traceability of conditions, and handling protects the sample during transitions. Together, they strengthen confidence that observed biological results reflect the experiment rather than storage-related loss of integrity.
At minimum, it should identify the material, storage temperature, suitable container, labeling requirements, handling steps, and monitoring approach. The workflow should also account for retrieval and recovery, because preservation is useful only if the sample can be accessed without compromising quality. Standardizing these elements improves consistency between storage events and experiments.
Transport should preserve the protocol’s controlled low-temperature conditions from departure through receipt. Researchers need suitable containers, clear labels, careful handling, and monitoring so that temperature-sensitive samples remain identifiable and protected. This is particularly important for materials intended for cell culture, molecular analysis, clinical research, or biobanking, where compromised integrity can affect later results.
Cold storage protocols support several stages of biological research, including maintaining cell-culture materials, organizing biobank collections, preserving reagents, and protecting samples for molecular or clinical analysis. They also apply to organisms and temperature-sensitive materials during transport. The main research benefit is continued access to samples with better integrity and reproducibility than poorly controlled storage would provide.
