## Description

Fully integrated, oil-free vacuum pump and controller ideal for use with a rotary evaporator for stripping solvents with boiling points of 160Â°C (320Â°F) or higher, such as DMF, or low boiling point solvents such as methylene chloride. The system's two-stage, flexible diaphragm pump is equipped with fluorinated plastics on all wetted surfaces to resist chemical vapors. The system's intuitive design incorporates a numeric keypad and electronic variable control valve for precise/reproducible vacuum control with programmable dual set-points, timer, memory, repeat, and anti-bumping functions. The one-touch anti-bumping/foaming button is especially useful when pumping low boiling point solvents to minimize foaming or bumping within the flask. The corrosion resistant and oil-free PTFE diaphragm pump and self-cleaning purge automatically run for two minutes at shutdown to rid the pump of residue. This ensures longer diaphragm service life and reduced downtime by cleaning the pump when the process is finished. The system also features a glass inlet separator that helps prevent the pump from ingesting liquids or particulates, a fully integrated vacuum controller that can store up to five program settings to allow hands-free/walk-away operation, and an exhaust separator that collects any liquid droplets or particulates flushed from the pump during the self-cleaning fresh air purge cycle. The 115V pumps are supplied with a North American 115V plug. The 230V pumps are supplied with a Continental European (Schuko) plug with IEC cord. The 115V pump is CSA certified. The 230V pump is CE marked.
