GWV High Capacity Groundwater Sampling Capsules

Superior flow rates and higher throughputs than competitive devices

75 Metals Analysis Certification is printed on each package.
Meets filtration requirements of the U.S. EPA.
Available in a variety of pore sizes to meet regional regulatory requirements.
Save time and money. Self-contained devices reduce the need for costly decontamination and multiple filter change steps associated with reusable filter holders.
Ensure rapid filtration. GWV provides five times the filtration area of conventional 142 mm filters.

Designed for the preparation of groundwater samples for dissolved metals analysis.
Reduces the need for multiple changes when filtering particulate-laden samples.

Groundwater Capsules Certification

Pall Life Sciences certifies that GWV and AquaPrep 600 groundwater capsules typically exhibit non-detectable levels of metal extractables when a metals analysis is performed on their effluent. ICP-MS instrumentation in a Class 100 clean- room was used in performing analysis of the metals listed above. All testing was performed at an independent laboratory utilizing approved U.S. EPA test methods. This certification is included in each product package.
