Fully automated open access platform for rapid, combined serial evaporation and sample reformatting

Area of Science:

• Analytical Chemistry
• Chemical Engineering
• Laboratory Automation

Background:

• Traditional solvent evaporation methods can be time-consuming and labor-intensive.
• Current automated systems often lack efficiency and flexibility in sample handling.
• Bumping during solvent evaporation can lead to sample loss and inaccurate results.

Purpose of the Study:

• To develop a novel, high-throughput evaporation platform.
• To integrate an automated sample handling system with a new evaporator design.
• To improve solvent removal rates and automation capabilities compared to existing technologies.

Main Methods:

• Utilized the Vaportec V-10 evaporator with a high-speed rotation motor (approx. 6000 rpm) and controlled heating.
• Implemented an intelligent algorithm for precise control of pressure, temperature, and end-of-run detection.
• Integrated robotics for automated sample transfer and reformatting from source to daughter containers.

Main Results:

• Achieved significantly faster evaporation rates for a wide range of solvents compared to vacuum centrifugal evaporators.
• Demonstrated efficient solvent removal without bumping due to centrifugal force.
• Successfully automated sample reformatting and evaporation with minimal user intervention.

Conclusions:

• The developed high-throughput evaporation platform offers substantial advancements in speed and automation.
• The integrated system provides a flexible solution for sample reformatting and efficient solvent removal.
• This novel approach enhances laboratory efficiency and reduces manual handling in sample preparation.
