- Disposable, EPA-accepted method for collecting groundwater prior to dissolved metals analysis.
- Meets USEPA requirements for 0.45 µm filtration. Certificate included with each capsule shows lowest detectable level (LDL) analyses for 67 metals and 2 anions.
- Low-extractable filter and housing materials minimize background during sample analysis.
- Available with three different pore sizes to suit a variety of water conditions: 5.0 µm for high particulates; 1.0 µm for normal particulates; 0.45 µm for relatively clean water.
- Four times more filter area than 142 mm disc filters for faster flow rates and higher throughput.
- Ready to use. No assembly required.
Product Certification
Millipore Groundwater Sampling Capsules come with a certificate showing the extraction levels, which are available on the Millipore web site.
