UNSPSC 41122109: Petri pads

UNSPSC 41122109 Petri pads is a Commodity code under which state and local government procurement offices buy laboratory consumables and reagents, particularly petri dishes and growth media used in microbial testing, water quality analysis, and public health surveillance. Recent opportunities show state health departments, transportation agencies, and municipalities soliciting petri pads and related laboratory supplies as components of broader consumables packages for drinking water analysis, wastewater surveillance, and environmental testing programs. The Texas Health and Human Services Commission (HHSC) and Colorado Department of Public Health and Environment (CDPHE) are repeat active buyers, with most solicitations issued as IFBs or RFQs targeting chemistry labs, water treatment operations, and surveillance units. Petri pads typically appear bundled with other laboratory consumables—septa, liners, protective gloves, industrial wipes, detector components, and reagents—within single solicitations that reflect the integrated workflow of modern analytical labs. Quantities are often modest (1 to 20 units per line item), but annual spend on the full consumables bundle can reach $50,000 to $75,000 or higher depending on testing volume and program scope.

Purchasing activity concentrates in Texas and Colorado, with secondary activity in California, Mississippi, and South Dakota based on recent postings. The Texas Health and Human Services Commission issued IFB HHS0018026 (Standards, Consumables and Instrument parts) with a response deadline of October 9, 2026, covering 19 line items with historical annual value between $50,000 and $75,000 for the Organic Chemistry Group's drinking water analysis work under the Safe Drinking Water Act. The City of Arlington, Texas solicited an annual requirements contract (IFB 270018, due September 17, 2026) for laboratory supplies and chemicals serving the city's Laboratory Services and two water treatment plants. Colorado's CDPHE Laboratory Services Division has been the most active buyer, issuing sole-source renewals for specialized reagents and consumables from Qiagen, Standard BioTools, Ceres Nanosciences, and Twist Bioscience (all posted May 2026 with May 22–28 response windows) valued between $1.4 million and $3.5 million each over multi-year terms; while these are sole-source procurements, they signal substantial recurring demand for lab consumables in state public health operations.
