Rotary evaporator access
service

A rotary evaporator is a laboratory instrument used to remove or evaporate solvents from a solution in a controlled manner through a combination of heating, vacuum pressure, and flask rotation. The process enables solvent evaporation at relatively lower temperatures, making it suitable for sample concentration, solvent recovery, and processing of heat-sensitive samples.

Use of the rotary evaporator for solution concentration, solvent removal, and/or solvent recovery based on the operating conditions specified by the user and within the capacity of the equipment.

• Equipment: Rotary Evaporator
• Function: Evaporation, concentration, and/or recovery of solvents from solutions or extracts
• Sample: Solutions, extracts, extraction fractions, or other materials suitable for rotary evaporation
• Sample Preparation: Prepared by the user; sample preparation is not included in the service
• Operating Parameters: Water bath temperature, vacuum pressure, rotation speed, and processing time are determined based on the sample characteristics and user's requirements
• Solvents: Solvents compatible with the rotary evaporator and meeting applicable laboratory safety requirements
• Service Output: Concentrated sample/extract and/or condensed solvent recovered during the evaporation process
• Operation: Performed by the user according to the applicable SOP and under laboratory staff supervision

1. The user must provide information regarding the sample type, sample volume, solvent type and composition, and intended purpose of the rotary evaporation process.
2. Samples must be suitable for evaporation and must not contain coarse particles or materials that could cause blockage or damage to the system.
3. The sample volume must be within the capacity of the evaporation flask and must not exceed the specified filling limit.
4. The user must ensure that the sample and solvent are compatible with the flask, seals, tubing, and other equipment components.
5. Flammable, toxic, corrosive, highly volatile, or otherwise hazardous solvents must be declared to laboratory staff and may only be used following appropriate risk assessment and approval.
6. The use of organic solvents must comply with the applicable SDS/MSDS, ventilation/fume extraction requirements, and personal protective equipment (PPE) procedures.
7. The user must provide the required operating conditions, including water bath temperature, vacuum pressure, and rotation speed, where these have been determined based on the experimental method.
8. Vacuum pressure and temperature should be adjusted gradually to minimize the risk of bumping, foaming, overheating, or sample loss during evaporation.
9. The evaporation flask must be properly installed and secured before operation.
10. Users are not permitted to modify or disassemble the vacuum system, condenser, seals, or other equipment components without authorization from laboratory staff.
11. The vacuum system must be checked before use to ensure that there are no leaks that could interfere with the process or create a safety hazard.
12. After completion of the process, the user must ensure that the system is in a safe condition before removing the flask or releasing the vacuum.
13. The flask, work area, and equipment components that come into contact with the sample must be cleaned after use.
14. Users must follow the applicable SOPs, laboratory safety procedures, and equipment operating instructions.
15. The user is responsible for the quality, safety, and suitability of the samples and solvents used.

• Samples must be homogeneous or otherwise suitable for rotary evaporation.
• Samples containing significant amounts of solids should be filtered or separated before the evaporation process.
• Solvents must have properties suitable for evaporation and be compatible with the equipment.
• High-boiling-point or difficult-to-evaporate solvents require special consideration regarding the operating temperature and vacuum pressure.
• Solvents that produce hazardous, flammable, or corrosive vapors require special handling in accordance with laboratory safety procedures.
• Users must provide the SDS/MSDS for hazardous solvents or materials when requested by laboratory staff.

The rotary evaporation service may produce:

• Concentrated extracts or solutions
• Samples with reduced or removed solvent content
• Condensed solvent recovered during the evaporation process
• Samples ready for subsequent analysis or processing
