\nRotary evaporators can release hazardous solvent fumes while using or cleaning the system, or while emptying the solvent trap (UCLA, 2010)<\/a>. Operators should consider fume inhalation risks and utilize respiratory engineering controls, such as a ductless fume hood or exhaust hood, to protect their safety and the overall laboratory\u2019s safety.

What are Rotary Evaporators?<\/h2>\n
\"Rotary<\/a>

IKA Rotary Evaporator (Source)<\/a><\/p><\/div>\n

Rotary evaporators, or rotovaps, use an increased temperature and reduced pressure to quickly remove solvents from less volatile samples (Rotary Evaporation, 2021)<\/a>. Rotary evaporators spin the flask containing the sample to increase the surface area while heating it in a water bath. Meanwhile, the vacuum reduces the pressure of the sample to lower the boiling point of the solvent (Rotary Evaporation, 2021)<\/a>. Once the solvent boils, it turns to vapor, then cooled through the condenser, and is collected in the solvent trap or flask. Rotary evaporators efficiently and gently remove solvents from the sample while dramatically reducing procedure time (Nichols, 2022)<\/a>. This process exposes the sample to a lower temperature, because of the reduced pressure, in turn protecting the sample from excessive heat.<\/p>\n

\nRotary evaporators are very common in everyday laboratory procedures and can be used to distill, dry, recover, and extract samples (LabX, 2021)<\/a>. Rotary evaporators can also be used for:
\n 
\n\u2022 Create concentrated solutions or suspensions (KNF)<\/a>
\n\u2022 Crystallization or recrystallization (KNF)<\/a>
\n\u2022 Solvent distillation and recycling (KNF)<\/a>
\n\u2022 Chemical synthesis (KNF)<\/a>
\n\u2022 Prepare distillates and extracts for cooking (KNF)<\/a>
\n\u2022 Extractions for biofuel research and the oil and gas industry (Darcel, 2022)<\/a>

Rotary Evaporator Safety<\/h2>\n
\"Rotary<\/a>

Due to the use of high temperature, reduced pressure, and volatile chemicals, operating rotary evaporators requires following safety guidelines to ensure the operator\u2019s safety as well as the overall lab safety. The different components of a rotary evaporator create distinct safety concerns including (Miller, Liu, 2017)<\/a>:
\n\u2022 Pinch point from the motor or moving parts
\n\u2022 Implosion and explosion from vacuum\u2019s reduced pressure
\n\u2022 Inhalation of harmful fumes if solvent vapors escape
\n\u2022 Burns from the hot water bath
\n\u2022 Cuts from sharp glass of broken components<\/p>\n

10 Rotary Evaporator Safety Rules<\/b><\/h3>\n
\"Rotary<\/a>

\nLaboratory professionals should always follow the manufacturer\u2019s safety guidelines for safe rotary evaporator usage. In general, the following Rotary Evaporator safety rules offer ways to help improve safety.
\n 
\n1. Read Material Safety Data Sheets (MSDS) of all chemicals to ensure solvent and mixture can safely undergo rotary evaporation (Miller, Liu, 2017)<\/a>.
\n2. Don\u2019t use highly reactive materials in a rotary evaporator to prevent possible explosions (UMass Amherst)<\/a>.
\n3. Wear appropriate PPE including eye protection, gloves, lab coat, shoes, etc. (Miller, Liu, 2017)<\/a>.
\n4. Ensure glassware has no cracks to prevent possible explosions\/implosions (Miller, Liu, 2017)<\/a>.
\n5. Always empty the solvent trap or solvent collection flask before use to prevent mixing incompatible chemicals (UCLA, 2010)<\/a>.
\n6. Start with a clean bump trap to allow easy sample recovery and prevent contamination if bumping occurs (UCLA, 2010)<\/a>.
\n7. Securely fasten the flask and bump trap with clips to prevent breakage (UCLA, 2010)<\/a>.
\n8. Use the lowest possible temperature for boiling to prevent bumping (Miller, Liu, 2017)<\/a>.
\n9. Use in a fume hood or exhaust hood to prevent vapors from releasing into the lab (LabX, 2021)<\/a>.
\n10. Ventilate properly after use before disassembly to prevent the release of solvent vapors (LabX, 2021)<\/a>.<\/p>\n

When to Use a Fume Hood<\/b><\/h3>\n

Utilizing a fume hood during rotary evaporation can help protect users from inhaling hazardous solvent fumes and injuries from implosion\/explosion. Below are safety considerations for laboratories to examine when determining when to use a fume hood for rotary evaporation.
\n 
\n\u2022 Using volatile solvents that create toxic or noxious fumes<\/b> \u2013 Solvent vapors can escape from a rotary evaporator posing potential health risks (O\u2019Driscoll, 2018)<\/a>. Certain chemicals create more of a risk. See the Solvent Fumes discussion in the next section for more information.<\/i><\/a>
\n\u2022 When there\u2019s a risk of explosion or implosion<\/b> \u2013 The fume hood can help provide a protective barrier between the user and the rotary evaporator to contain broken glass or pieces (O\u2019Driscoll, 2018)<\/a>.
\n\u2022 To protect against other safety concerns such as pinch points or burns<\/b> \u2013 Fast moving parts and high temperatures can cause safety hazards. The fume hood offers a protected area to separate it from the user helping to remove additional safety concerns (O\u2019Driscoll, 2018)<\/a>.<\/p>\n

\n

<\/a><\/p>\n

Solvent Fume Exposure from Rotary Evaporators<\/b><\/h3>\n

Rotary evaporation utilizes a wide variety of different solvents. Solvent fume inhalation can occur while emptying the solvent trap or collection flask, during disassembly, and during use especially when using toxic solvents that are known to produce noxious fumes (O\u2019Driscoll, 2018)<\/a>. Exposure side effects can vary, but protecting against any exposure can help employees and colleagues feel safer during work. OSHA regulates the exposure of most of the commonly used solvents for rotary evaporation. OSHA\u2019s permissible exposure limit (PEL) is legally required and enforced for all workplaces while the NIOSH recommended exposure limit (REL) provides additional safety precautions. The chart summarizes common solvents, OSHA PEL, NIOSH REL, and possible health risks from inhalation (Miller, Liu, 2017)<\/a>.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

Rotary evaporators can release hazardous solvent fumes while using or cleaning the system, or while emptying the solvent trap (UCLA, 2010). Operators should consider fume inhalation risks and utilize respiratory engineering controls, such as a ductless fume hood or exhaust hood, to protect their safety and the overall laboratory\u2019s safety.
