BRAND NAME OR EQUAL DESCRIPTION

Background: The U.S. Geological Survey (USGS), National Water Quality Laboratory (NWQL), located in Lakewood, CO, has a requirement for filters for use in Water Mission Area (WMA) water sampling and testing programs. The USGS, WMA, and NWQL strive to maintain national consistency in all environmental samples collected by their personnel. The scientific analytical data from these samples is available and presented for use by other agencies and the public. It is extremely important that the filters acquired hereunder will continue to provide consistency with the data that has been obtained, in some cases, for over a decade. Consistency in data is critical for the NWQL and USGS programs across the country for which the Lab does analysis. Unlike commercial labs, the NWQL, and the USGS programs they support, monitor trends in the data.

Scope: This purchase description covers the requirement for filters required by the NWQL to conduct their analysis.

Requirement: This purchase description identifies the characteristics and level of quality necessary to satisfy the Government’s requirements. The salient characteristics applicable to all products offered are specified herein.

The following information concerning providers of the item is provided for the convenience of offerors:

Cytiva (www.cytiva.com) and GeoTech (www.geotechenv.com).

Offerors proposing products other than those listed shall provide items that meet or exceed the salient characteristics identified below. Offerors shall include product documentation, including certificates of analysis (COAs) for the two most recent lots, which verify that the product meets or exceeds the salient characteristics specified.

Salient Characteristics:

1. Required products:

Filter, Capsule, Cytiva (Pall) Part #12180 or GeoTech dispos-a-filter, GeoTech Part #73050004, Pack/50 (NFSS #Q398FLD)

• Shall have the following filter media: Versapor® membrane (acrylic copolymer on a non-woven support).

• Shall be a self-contained, disposable device with a housing made of polypropylene.

• Shall have of an effective filtration area of no less than 700 cm2.

• Shall have Inlet/Outlet Connections of 1⁄8 in. MNPT.

• Shall have a maximum operating temperature of no less than 88 °C (190 °F).

• Shall have maximum operating pressure of no less than 3.4 bar (340 kPa, 50 psi) at ambient temperature.

• Shall have a pore size of 0.45 µm.

• Shall have a flow rate of no less than 500 mL per minute.

• Shall meet or exceed the limits of detection listed in the table in Section 2: Vendor tested limits of detection for the capsule filter.

2. Vendor tested limits of detection for the capsule filter:

Limits of Detection (LOD) for stated analytes for capsule filters.

Analysis is performed following a 1-liter flush of ultrapure (18 Megohms) water for the capsule filters.

3. Labeling requirements for both products shall be in accordance with the following:

a. All inks and labels shall be waterproof and on the outside of the housing.

b. Pad print or affix a label to the casing of the filter so as not to interfere with the flow path of the water.

c. At a minimum, the pad print or label shall contain the following information:

• Manufacturer or supplier’s name

• Filter pore size (e.g. 0.45 um)

• Part # XXXX

• Lot # XXXX

d. Capsule filters only: Pad print or affix a directional arrow indicating flow path on the outside of the capsule. The directional label shall be waterproof and shall not peel off or be destroyed during or after contact with water.

4. Lot requirements for the capsule filter:

All filters shall be from one capsule and media/membrane lot per shipment. Include a certificate of compliance/analysis with each shipment. Certificate of compliance/analysis shall list the lot number and filter media/membrane of the filters.

5. Single lot requirement:

All capsule filters per delivery order must be from the same lot/run and have the same capsule lot number and membrane lot number. Individual capsule filters outside of the lot/run will not be technically acceptable.

Quality Assurance: The acceptability of items delivered hereunder will be determined by quality assurance (QA) testing of each lot at the NWQL. The capsule filters shall be of sufficient quality to support the detection limits attainable by the NWQL for all applicable methods. In addition to the placed order, the offeror shall supply fifty (50) capsule filters of each lot to accommodate this QA testing. These capsule filters shall be provided at no cost to the Government. Acceptance of the entire lot will be based on the results of these analyses.
