UNSPSC 41104929: Laboratory filter papers

Used for separating different substances of different physical states.

UNSPSC 41104929 Laboratory filter papers is a Commodity code, but the recent state and local opportunities posted under this code predominantly reflect water and wastewater treatment membrane procurement—reverse osmosis (RO) membrane elements, submerged microfiltration (MF) membranes, and associated replacement parts for municipal recycling and treatment facilities—rather than laboratory filter papers themselves. The scope includes original equipment manufacturer replacement membranes meeting NSF certification requirements, spare interconnectors, end-cap adapters, and O-rings compatible with specific pressure vessel models and rack systems. Water districts and municipal utilities dominate the issuing-body mix, with West Basin Municipal Water District appearing twice (seeking RO membranes for the Juanita Millender-McDonald Carson Carson Regional Water Recycling Plant and MF membranes for the Edward C. Little Water Recycling Facility). A school district (Forsyth County Schools) posted for ERU filters with minimal specification detail, and construction-oriented procurement appears in Collier County's RO skid rehabilitation scope. One sourced opportunity—the City of Palm Bay laboratory testing services solicitation—lies outside the code's nominal scope entirely, addressing comprehensive water and wastewater analytical testing rather than filter products.

Geographic activity centers on California (West Basin solicitations) and Florida (Collier County and City of Palm Bay), with North Carolina present (Forsyth County Schools). West Basin Municipal Water District's RO membrane solicitation (IFQTH0119, due February 26, 2026) requested 852 elements for 8 x 40 inch reverse osmosis membranes with 60-day delivery, $8,600 daily liquidated damages for delays, and a 3% SBE/LBE evaluation credit or 6% if both designations apply. West Basin's MF membrane pre-qualification (RFQTH0131, due May 26, 2026) required suppliers to demonstrate three years' municipal experience, provide two U.S. municipal wastewater references with minimum 3 million gallons per day capacity, and furnish NSF-60 and NSF-419 certifications. Collier County's RO skid rehabilitation (Bid 26-8646, due April 24, 2026) encompassed 252 new 600-psi pressure vessels, 1,512 RO elements, and control system modifications with a $4,000,000 budget and $1,093 daily liquidated damages. The code shows material mismatch between its nominal "laboratory filter papers" designation and the water treatment membrane and equipment replacement activity actually being procured.
