A solvent is a substance, most often a liquid, that can dissolve other substances. Here, the substance being dissolved is called a solute. When a solvent and a solute combine, they form a solution - a homogenous mixture of both the solvent and the solute. Water is a universal biological solvent. Its polar structure allows it to dissolve many other polar compounds. The ability of water to dissolve is governed by a balance between water molecules binding to each other and binding to the solute. A...

Source: Hsin-Chun Chiu and Tyler J. Morin, laboratory of Dr. Ian Tonks—University of Minnesota Twin Cities Schlenk lines and high vacuum lines are both used to exclude moisture and oxygen from reactions by running reactions under a slight overpressure of inert gas (usually N2 or Ar) or under vacuum. Vacuum transfer has been developed as a method separate solvents (other volatile reagents) from drying agents (or other nonvolatile agents) and dispense them to reaction or storage vessels while...

Rotary Evaporation to Remove Solvent

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...

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...

A new way for the production of biopolymer-based aerogels by carbon dioxide (CO2) induced gelation is shown. The technique utilizes pressurized carbon dioxide (5 MPa) for the production of biopolymer hydrogels and supercritical CO2 (12 MPa) to convert gels into aerogels. The only solvents needed besides CO2 are water and ethanol.
FAQs
Chemical compatibility determines which solvents can share a storage area and which must remain segregated. Incompatible materials may create hazards if they contact one another, so storage decisions should consider both the solvent’s chemical properties and the hazards identified for it. Applying compatibility rules helps prevent accidental reactions while maintaining an organized laboratory environment.
Hazard classification identifies risks associated with individual solvents, while segregation prevents materials with incompatible hazards from being stored together. This distinction matters because organizing containers only by name or frequency of use may place unsafe combinations in the same location. Using both principles supports safer access, reduces accidental exposure or reactions, and strengthens laboratory compliance practices.
Appropriate containers protect solvents from contamination and degradation, while clear labels ensure that researchers can identify contents and handle them according to the relevant storage requirements. These controls support reagent reliability in biology workflows, where compromised solvents may affect cell culture, molecular biology, histology, or analytical procedures. Consistent identification also improves inventory oversight and daily laboratory decisions.
A practical workflow begins by identifying each solvent, confirming its hazard classification and compatibility requirements, and selecting an appropriate container. Staff then label containers clearly, segregate incompatible materials, and place them under the required containment and access conditions. Regular organization and inventory management help laboratories locate reagents efficiently, recognize storage problems, and maintain consistent safety practices.
A protocol may incorporate ventilation, secondary containment, and access controls according to the hazards and laboratory setting. Ventilation supports safer handling environments, secondary containment helps limit the spread of leaks or spills, and controlled access restricts unnecessary contact with hazardous materials. Together, these measures complement compatibility-based organization rather than replacing it.
Biology laboratories depend on solvents across cell culture, molecular biology, histology, and analytical procedures, so storage conditions can influence both safety and experimental reliability. A consistent protocol helps protect reagents from contamination or degradation while reducing risks such as fire, toxic exposure, and accidental reactions. It also supports efficient work, inventory control, and regulatory compliance.
