Chemistry and life science laboratories utilize lab vacuum pumps for applications such as providing suction to drive the aspiration or filtration of liquid or suspended samples, and inducing or controlling solvent evaporation by reducing vapor pressure. When choosing a lab vacuum pump, two key specifications are ultimate vacuum and pumping speed, or flow rate. Other important considerations are the type of solvent you will be working with, and whether you will need specific vacuum levels, an accessory that will capture vapors, or options that allow the pump to run more than one vacuum application at a time.
