Traditional lab vacuum systems are often plumbed with standard copper piping. Initially this may provide the necessary system integrity (vacuum tightness), however, over time piping exposure to common harsh chemicals used in life science and chemistry laboratories can degrade these system components resulting in pitting and occlusions. This can result in performance losses and possible chemical and biological exposure behind the walls of the lab and other parts of the facility. This video shows accelerated life testing of standard central vacuum (copper) piping compared to chemical resistant PTFE local vacuum network piping. The results are compelling.
