Speedvacs use centrifugal force along with heat and radiant light to evaporate solvents from samples, vacuuming them out and collecting them into a cold trap. All of our SpeedVac Vacuum Concentrators are inspected and tested by our service team. Our trained technicians check for functionality and defects during initial inspection. During our testing and validation phase, electronics, lamps, motors are inspected and stress tested to ensure product is performing up to specification. In addition, we also test vacuum rate and chamber cooling on models that include this feature, to validate they’re running at factory specification. Each system is backed with our standard warranty and ships within three business days.
