Pall tests GWV Groundwater Sampling Capsules with 75 Metals and Anions to ensure minimum detectable levels in their composition. See the Certification below.
GWV High Capacity
Groundwater Sampling Capsule
AquaPrep™ 600 Groundwater Sampling Capsules are optimized for minimal background in dissolved metals analysis of water samples. With 600 cm2 effective filtration area (EFA), these capsules have four times higher EFA than 142 mm disc filters, reducing the need for multiple filter changes during filtration and ensuring rapid sample filtration.
For a cost-effective alternative to high capacity capsule filters for filtration of non-particulate laden samples, use AquaPrep Groundwater Sampling Devices with 19.6 cm2 EFA.
