Envirochek® and Envirochek HV Sampling Capsules

For the Concentration and Recovery of
Cryptosporidium Oocysts and Giardia Cysts
from Source or Finished Water

• Simple to use. No assembly or cleaning of filter holders or elution equipment.
• Saves time by allowing the processing of multiple samples at the same time.
• Disposable design eliminates crosscontamination and false positives.
• Typically greater than 70% recovery of target organisms.
• Eliminates false negatives with 1 μm pore size membrane for retention of Cryptosporidium and Giardia. Envirochek HV capsules are 100% integrity tested.
• Safer to use. Self-contained capsules mean that the potentially contaminated filter element does not need to be handled or cut apart.
• Capsules are serialized for traceability.

• Envirochek sampling capsules are validated and listed in U.S. EPA Methods 1622 and 1623, and used for sampling source water for Cryptosporidium and Giardia.
• Envirochek HV capsule is designed for sampling up to 1,000 L or more of treated water and is validated for up to 50 L of source water.
• Envirochek HV capsules, PNs 12096 and 12097, are approved for the United Kingdom DWI regulatory testing of finished water.
• Envirochek capsules are listed in ISO/DIS 15553-2006.

Laboratory Shaker 

 

For effective elution of Cryptosporidium oocysts and Giardia cysts off Envirochek sampling capsules

• Meets U.S. EPA requirements for Methods 1622 and 1623 for recovery of organisms.
• Processes up to eight Envirochek sampling capsules at one time.
• Accurate and consistent shaking speed with a digital read-out.
• Simulates human wrist action to save time, reduce fatigue, and provide consistent results.
• CE marked for European community use.
• UL-listed power cord also included.

Applications

• Specifically designed for use with Pall’s Envirochek sampling capsules for the elution of Cryptosporidium oocysts and Giardia cysts. Add an elution buffer to the capsule and the shaking action elutes the captured organisms off the membrane surface for further concentration and identification.
• Shaker accommodates up to eight Envirochek sampling capsules at one time.

Laureth-12

Laureth-12 is a component required in the elution solution. Available in paste form, one 50-gram bottle per package. One bottle has sufficient volume for approximately 200 tests. For the complete formulation, refer to the Envirochek HV sampling capsule protocol, PN 33210. The formulation can also be found in U.S. EPA Methods 1622 and 1623.

The Envirochek® HV capsule has been validated for testing source water up to 50 L and for high volumes of drinking water analysis up to 1,000 liters (see Table 2). High flow rates and throughput are achieved due to the high filtration area that comes from the patented pleated design. This pleated design provides 1,300 cm2 of filtration area that allows for high flow rate at very low differential pressures. This means gravity feed or smaller pumps can be used and easily carried into the field for site sampling. Site sampling eliminates the need for carrying and shipping bulky containers of water.

The patented recovery method used with the Envirochek HV capsule allows for processing up to eight filters at one time, saving valuable lab time. The method is the easiest and simplest one available.
