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.
