LABOPORT Mini Vacuum Pump Testimonial

Many of the activities in our chemistry laboratories incorporate suction filtration, where water aspirators were used as a vacuum source for years. These aspirators were often unable to provide a reliable low pressure when all the students in the lab needed to complete a filtration. After trying one KNF LABOPORT Mini pump on a trial basis, the department has chosen KNF pumps as the vacuum source in all laboratories. Soon, the chemistry department will be moving into a new 'green' building, where managing water consumption will be a priority. All of our new laboratories will be outfitted with KNF pumps.
