Test for residual water in flexible endoscopes

HydroCheck-E can detect a very small amount of residual water inside an endoscope channel to avoid recontamination during storage.


  • Easy to use test kit
  • Verify the dryness of flexible endoscope channels
  • Purple colour change indicates residual water in the tested channel
  • Detection limit of 0.05 μl residual water
  • Immediate result, no incubation required


A swab is used to sample any residual water from the endoscope channel and is then tested with the HydroCheck-E. A purple spot on the swab indicates residual water in the tested channel.
