Dimethyl sulfoxide (DMSO) is an essential solvent in biological and chemical research due to its ability to dissolve both polar and nonpolar compounds. It is widely used in drug discovery, cryopreservation of cells, and as a reaction medium in organic synthesis. However, its high boiling point and strong solvent properties make its removal difficult. Inefficient DMSO removal can result in:

Sample degradation and compromised data quality
Loss of valuable analytes
Lengthy evaporation times that hinder lab efficiency
Potential contamination due to solvent residues
Challenges in downstream processing and analysis

This article explores the most effective DMSO removal techniques and provides insights into optimizing your workflow for improved sample recovery, laboratory productivity, and overall research success.

2. Traditional Methods for DMSO Removal: Challenges and Limitations

2-1. Rotary Evaporation – A Common Yet Suboptimal Approach

Rotary evaporators (rotovaps) are a widely used method for solvent removal, but they present significant limitations when handling DMSO:

High boiling point: DMSO’s boiling point of 189°C requires elevated temperatures, increasing the risk of thermal degradation.
Bumping and sample loss: Volatile samples frequently experience sudden boiling, leading to potential sample loss.
Time-intensive process: The evaporation process is slow and requires constant monitoring, making it labor-intensive.
Inconsistent results: Variability in solvent removal efficiency can impact reproducibility.

2-2. Lyophilization (Freeze Drying) – Effective but Slow

Freeze drying is another common approach for removing DMSO, particularly for biological samples. However, it has several disadvantages:

Requires freezing and vacuum drying, significantly extending processing times.
Not ideal for heat-sensitive compounds, as freeze-drying conditions can still impact molecular integrity.
High operational costs, requiring expensive equipment and ongoing maintenance.
Limited scalability, making it impractical for high-throughput laboratories.

2-3. Alternative Techniques and Their Drawbacks

Other methods, such as solvent extraction and chemical treatments, have been explored for DMSO removal, but they often introduce new challenges:

Solvent extraction: May require additional purification steps and can lead to sample contamination.
Chemical treatment: Can alter sample composition and is not always suitable for sensitive compounds.

3. Advanced DMSO Removal Techniques: Faster and More Efficient Solutions
