Self-Cleaning Dry Vacuum System are complete vacuum solutions for rotary evaporation. All three systems (2025, 2027, 2028) feature rugged corrosion resistant PTFE diaphragm pumps for low maintenance and long life. All models feature adjustable vacuum to optimize for a variety of solvents. Also included with all models: digital or analog vacuum read-out, inlet and outlet traps to protect the pump and exhaust line from liquids, gas ballast or no bumping/foaming key as an emergency “bump stop”, and automatic self-cleaning purge at shutdown. The self-cleaning feature and patent pending vacuum control technology contribute to the pumps’ long diaphragm life.
All models are 35 L/min at 60 Hz (29 L/min at 50Hz).
• Anti-bumping/foaming feature with controlled evaporation rate
• Rugged corrosion resistant PTFE construction
• Self-cleaning for long life
• 2 Torr (2.7 mbar) models strip DMF at 35°C bath temperature
• 9 Torr models (12 mbar) models strip most common solvents
• Programmable Model 2028 features walk away automation
Model 2025 general usage meter vacuum read-out, vacuum regulator, 9 Torr ultimate vacuum for fast stripping of most common rotary evaporation solvents. Fast stripping of rotary evaporator solvents with boiling point < 100ºC.
