The VAR-B system for flow-proportional sampling utilizes the vacuum/pressure principle as well as special technology for contactless sample volume metering. This makes it especially well-suited for very dirty sample media.

  • Fast volume metering
  • Minimizes sedimentation in the metering vessel
  • Limits the max. volume to be drawn
  • No electrodes to clean
  • Simple switching to fixed volumes
Sample MediaPure/ultrapure water to very dirty water/wastewater
Sampling ModesTime-, volume-, event-, flow-proportional
Sample VolumesVariable (dependent on flow) or fixed; adjustable: 20 - 250 ml
Optional: larger volumes
Wetted PartsBorosilicate glass (dishwasher-safe; resistant to acid, alkali, and temperature shock), silicone, PVC, stainless steel
Optional: custom materials upon request
