Achieving Efficient Rotary Evaporation: Selecting the Ideal Pump
Selecting the ideal pump is crucial for effective rotary evaporation. This page provides key information on features and benefits to help you choose the correct model for your application.
Key Features:
- Tunable Vacuum: Precisely control evaporation rate for various solvents
- Multiple Vacuum Levels: Choose from three levels to suit your specific needs
- Chemical Resistance: Rugged construction withstands harsh vapors
- DryFast Technology: PTFE dry vacuum pumps optimized for rotary evaporation, preventing bumping/foaming
- Durable & Low Maintenance: Oil-free design with PTFE heads and chemically resistant wetted parts
Solvent-Specific Performance:
- 9 torr DryFast: For common solvents
- 2 torr DryFast Ultra: For fast DMF and other challenging solvent removal
2014 Collegiate:
- High flow for low boiling point solvents (up to 80°C)
2034 / 2044 Research:
- Tunable vacuum for mid-range boiling point solvents (up to 110°C), ideal for larger flasks and solvents like DMF and toluene
Self-Cleaning Dry Vacuum Systems™
Eliminate downtime and ensure consistent performance with our Self-Cleaning Dry Vacuum Systems™, specifically designed for rotary evaporation. These complete solutions feature robust, chemically resistant PTFE diaphragm pumps, offering low maintenance and extended life. The integrated vacuum adjustment allows you to optimize evaporation for any solvent.
Experience Uninterrupted Operation with:
- Precise vacuum monitoring (digital or analog read-out)
- Enhanced pump protection (inlet and outlet traps included)
- Immediate intervention for bumping/foaming (prominent emergency stop)
- Automated maintenance (self-cleaning purge at shutdown)
The innovative self-cleaning technology and accurate vacuum control contribute to a longer diaphragm lifespan. All systems provide a consistent flow rate of 35 l/min at 60Hz (29 l/min at 50Hz).
