Filter, GWV High Capacity Groundwater Specifications
Here are the specifications for the Filter, GWV High Capacity Groundwater (Catalog Number/Order Code 2670500) which is the Pall® AquaPrep 600 Capsule with 0.45 μm Supor® membrane.

The United States Environmental Protection Agency requires that groundwater samples collected for dissolved or suspended metals analysis be filtered through a 0.45 μm filter (Method 3005 of Test Methods for Evaluating Solid Waste, Physical/Chemical Methods). These self-contained disposable filter units are designed to eliminate decontamination of a traditional filter holder, saving valuable time. The membrane filters used in these devices are specifically chosen so they do not contribute nor remove dissolved metals from the sample being collected. Vent ports on either side of the AquaPrep™ 600 capsule filters are both upstream to allow field technicians to use the capsule in any orientation while collecting the sample. A large filter area assures rapid collection of most groundwater samples and the  tapered hose barb connections allow easy insertion and removal of a variety of tubing sizes.

Materials of Construction:
Housings: Polypropylene
Filter Media: Supor membrane (hydrophilic polyethersulfone)
Effective Filtration Area: 600 cm 2
Inlet/Outlet Connections: 6.4-12.7 mm (1/4-1/2 in.) stepped hose barbs
Overall Length (including fittings): 14.5 cm (5.7 in.)
Maximum Operating Pressure: 4.1 bar (410 kPa, 60 psi) at ambient temperature
Maximum Operating Temperature: 60 °C (140 °F)

Instructions for Use:
1. After removing the filter from the package, place the outlet of the sampling pump tubing over the inlet fitting of the device.
NOTE: For capsules, the flow label should point away from the pump tubing; for the 50 mm filters, the printing should face the pump. Make certain the fitting is inserted far enough to avoid leakage around the seal. Tubing should then be securely clamped to the filter connections.
2. Opening a vent valve while filling the capsule and tightening once water has filled the capsule, may help eliminate air lock.
3. To ensure maximum performance, hold the device so that the outlet is pointing upward and slowly start the pump. When the water starts coming out of the outlet fitting, turn the device over and allow a small amount of water to flow through it, using the filtrate to wash the sample container.
4. After collecting the required amount of sample, remove the capsule or AquaPrep filter and dispose of properly.
5. These filters are for SINGLE USE ONLY.
