How long can I keep unsued media?

  • Bureau Veritas Laboratories supplied media is barcoded and tracked.
  • Limit supplies to 60 days at US locations, or up to 120 days at international locations. 
  • Return unused or expired media to our Lake Zurich laboratory for media credit, barcode retirement and recycling. 
  • Most filter media expiration dates are assigned for media management purposes, not due to loss of efficacy for sampling. If you are considering using expired media, contact our laboratory. 
  • Sites with a significant negative balance of un-returned media will be invoiced at media replacement cost.
