Heating and Cooling Curves

When a substance—isolated from its environment—is subjected to heat changes, corresponding changes in temperature and phase of the substance is observed; this is graphically represented by heating and cooling curves. For instance, the addition of heat raises the temperature of a solid; the amount of heat absorbed depends on the heat capacity of the solid (q = mcsolidΔT). According to thermochemistry, the relation between the amount of heat absorbed or released by a substance, q, and its...

We present a parametric driving method to cool an ultracold Fermi gas in a crossed-beam optical dipole trap. This method selectively removes high-energy atoms from the trap by periodically modulating the trap depth with frequencies that are resonant with the anharmonic components of the trapping potential.

The main purpose of this study was to adapt the needle immersed vitrification (NIV) procedure to cryopreserve whole zebrafish testes. Additionally, the repeatability of the method in five different zebrafish strains was tested.
FAQs
Heat moves from the warmer plate and sample contents toward a cooler platform, block, or surrounding environment. As the plate and wells exchange heat with that cooler setting, their temperature falls. Maintaining contact with the selected cooling surface helps keep samples under more consistent thermal conditions, reducing differences between wells and supporting reproducible biochemical results.
Lower temperatures slow temperature-dependent processes, including enzyme activity, degradation, and evaporation. This gives temperature-sensitive molecules greater protection during handling, incubation pauses, and transitions between analytical steps. The benefit is not simply a colder sample; it is better control over unwanted changes that could alter sample composition or affect measurements in enzyme assays and protein analysis.
The cooling outcome depends on how effectively heat leaves the plate and its contents and how consistently that condition is maintained. A cooler platform, block, or surrounding environment can establish the intended reduction, but changing thermal conditions may allow some samples to warm or cool differently. Consistent cooling therefore supports comparable treatment across the multiwell plate.
Place the multiwell plate on or within the selected cooler platform or block, or position it in the intended cooler surrounding environment. Keep the plate under that condition during sample preparation, an incubation pause, or a transition between analytical steps. This workflow limits temperature-related changes before the next operation and helps preserve consistent sample conditions.
It is useful when a workflow includes temperature-sensitive samples or pauses between sequential steps. Relevant settings include sample preparation, enzyme assays, protein analysis, and high-throughput processing in multiwell plates. Cooling helps maintain more consistent conditions while samples await the next operation, which can improve reproducibility and reduce changes caused by enzyme activity, degradation, or evaporation.
Researchers can preserve sample stability, slow unwanted biochemical changes, and maintain more uniform conditions across a plate. These effects support reliable handling during preparation and analytical transitions, while also improving reproducibility in assays and protein-related workflows. In high-throughput applications, consistent temperature control is especially important because many wells are processed within the same experimental sequence.
