SimulProbes Samplers

BESST’s SimulProbe is used in exploratory borehole drilling for environmental, water resource, agricultural, nuclear or mining industries, to collect a simultaneous soil core and groundwater or gas sample.


  • In-Situ Headspace Test: Enhances accuracy of on-site field measurements by directly sampling the soil-gas downhole, rather than using unreliable ex-situ methods, which damage sample integrity.
  • Quick setup and mobilization. System can be used with a photoionization detector (PID) for on-site results.
  • Volatile Organic Compounds (VOC) measurement: The VOC’s are directly collected from the ground which limits cross-contamination of the sample.
