To help our clients in the selection of field filtering apparatus and supplies we provide the following information and links.
- A peristaltic pump (also called a circulating pump or vein pump) and appropriate hosing is required with a 0.45µ filter capsule and sample bottle to collect samples.
- The filters or disposable capsules may be referred to as “QuickFilters” (QED Environmental System), “Dispos-a-filters” (Geotech Environmental Equipment), or Groundwater Sampling “Capsules”.
- Filters come in multiple capacities: for example QED offers the FF 8100 (standard capacity) and the FF 8200 (high capacity) QuickFilters. Hi capacity filters are better suited to sampling waters that are silty or particulate-laden.
- Users should check the vendor sites for specifications to ensure the background levels of contaminants meet their requirements.
- The filters are approximately $7.00/std capacity filter and up to $30 or more for high capacity filters. They are designed to be used once and disposed, so they are an expensive consumable if many samples are to be collected.
- The pump can run on 115v from a generator in the field, or, by 12v with a cigarette lighter plug for your vehicle.
- All these items can be purchased directly from the vendor.
