Checklist for Submitting Samples for Analysis

  1. Cleaning
    • Remove strings or other materials used to recover PRS® Probes.
    • Do not write on, mark or affix labels directly to PRS® Probes.
    • Hand scrubbing the adhering soil with a scrub brush and/or toothbrush while washing is necessary to remove sticky soil.
    • A pressurized washing system is often necessary for effective cleaning.
    • It is extremely important to ensure that the membrane, plastic casing and any cracks are absolutely clean because any contamination with soil will alter the results.
    • Watch our videos for probe washing techniques:
  2. Bagging
