Air in Tube Detector

  • Detects presence of air or liquid in tube
  • Non-invasive to fluid path- no product contact
  • Ultrasonic detector works in all tubes even if not transparent
  • Perfect for use in processes with single use fluid paths with no expendable costs
  • Can be integrated to control systems to measure the output and trigger response in the following types of processes:
    • Chromatography- to prevent air from being pumped into column
    • Depth Filtration- to detect end of batch
    • Tangential Flow Filtration- to determine the end-point of fed-batch or buffer additions
    • Bioreactors- monitor bioreactor feed lines to notify if addition sources are empty
  • Model available for direct integration to pump for shut off when air detected
