- Chemically resistant diaphragm pump ideal for integration with Buchi R-300 Rotavapor systems
- Speed regulation function reduces noise while maintaining consistent vacuum performance
- Operates quietly with a sound level range of 32 to 57 dBA for a low-noise lab environment
- Constructed with high-quality materials including PEEK, PTFE, FEP, and FKM for broad chemical compatibility
- Compact and lightweight design simplifies installation and mobility
- Compatible with standalone use or integration into complete vacuum systems
The Buchi V-300 Vacuum Pump is a chemically resistant PTFE diaphragm pump optimally suited to work with the Buchi R-300 Rotavapor System and/or the I-300/I-300 Pro Interface. The V-300 delivers a pumping volume of 1.8m^3/h with a final vacuum of 5 mbar (± 2 mbar), delivering reliable pressure for consistent distillations. The V-300 Vacuum Pump also features a speed regulation function, which allows the pump to reduce noise levels while by slowing the motor speed while still producing the same final vacuum of 5 mbar (± 2 mbar). This pump can be used individually to create a vacuum, or can be expanded to create a complete vacuum system with condensers, controllers, etc.
This vacuum pump is in excellent condition, and all of our equipment is fully tested to perform at factory specifications before being shipped.
The Buchi V-300 Vacuum Pump includes:
- > Power Cord
- > Operator's Guide
- > Full 180 Day Parts and Labor Warranty
