Envirochek® and Envirochek HV Sampling Capsules
  Envirochek® and Envirochek HV Sampling Capsules
100% capture and greater than 80% recovery of Cryptosporidium and Giardia cysts from source or finished water
  • Convenient, hassle-free design is your best choice for LT2 (U.S. EPA Long Term 2 Enhanced Surface Water Treatment Rule).
  • Save time - the protocol is faster and simpler than other methods, and allows for the processing of multiple samples at once.
  • Disposable design eliminates false positives from cross-contamination. The 1 µm pore size membrane eliminates false negatives.
  • Simple and safe - no filter holder assembly or cleaning required, and the self-contained capsule means that the potentially contaminated filter element does not need to be handled.
  • Approved by regulatory agencies worldwide, including U.S. EPA methods 1622 and 1623, United Kingdom DWI standard operating protocols, and ISO/DIS 15553.
Find LT2 testing labs in the USA that use Envirochek capsules.
