Mechanical Separator Removal

Mechanical separator removal is the physical elimination of a barrier, partition, or separating component from a biological sample or experimental system. It works by applying controlled force, such as pulling, cutting, scraping, or disassembly, to detach the separator while preserving the material or compartments being studied. In biology, this process can prepare samples for observation, restore contact between separated structures, or enable the collection and analysis of isolated cells, tissues, or biomaterials. Careful control of force and handling conditions helps limit structural damage and improves the reliability of downstream measurements and experiments.

Rotary Evaporation to Remove Solvent

2023

Source: Dr. Melanie Pribisko Yen and Grace Tang — California Institute of Technology Rotary evaporation is a technique most commonly used in organic chemistry to remove a solvent from a higher-boiling point compound of interest. The rotary evaporator, or "rotovap", was invented in 1950 by the chemist Lyman C. Craig. The primary use of a rotovap is to dry and purify samples for downstream applications. Its speed and ability to handle large volumes of solvent make rotary evaporation a preferred...

Source: Laboratory of Dr. Ana J. García-Sáez — University of Tübingen Most samples of interest are mixtures of many different components. Sample preparation, a key step in the analytical process, removes interferences that may affect the analysis. As such, developing separation techniques is an important endeavor not just in academia, but also in industry. One way to separate mixtures is to use their solubility properties. In this short paper, we will deal with aqueous solutions. The...
