UNSPSC 51241304 Ammonium alum (Commodity) encompasses laboratory reagents and chemical consumables for forensic analysis, drug screening, and public health testing—specifically the specialized reference materials, diagnostic kits, and chemical supplies that state and local public-health and law-enforcement agencies procure on a recurring basis. State and local jurisdictions soliciting under this code include state departments of public safety and forensic services, county sheriffs' offices, city utilities and laboratory services divisions, and university procurement operations. Recent opportunities span forensic DNA sequencing consumables and reagents (Life Technologies, Promega, Qiagen, Immunalysis, and ANDE Corporation products), Shiga toxin diagnostic kits, Next-Generation Sequencing (NGS) supplies, drug standards and controls, crime scene collection items (cotton swabs, GSR kits, evidence tubes), water-treatment chemicals (calcium hypochlorite, caustic soda, aluminum sulfate, sodium permanganate, sodium fluoride, phosphate blend), and laboratory supplies for municipal water systems and environmental testing.

Geographic activity concentrates in Texas (state procurement division, Texas A&M University, Arlington, Harris County), California (state health laboratory, public health lab goods set-aside), the District of Columbia (Department of Forensic Sciences, Department of Finance and Services), Connecticut (City of Meriden water treatment chemicals), and Georgia (Gwinnett County hydrogen peroxide). Representative recent opportunities include the Texas Comptroller of Public Accounts IFB 304T27175A11 for specialized genetic analyzer components and forensic screening kits (due October 20, 2026) serving the Texas Department of Public Safety and Parks and Wildlife; the City of Meriden ITB B026-55 for water-treatment chemicals including calcium hypochlorite, caustic soda variants, and permanganate (due June 25, 2026, with one-year term and renewal options); Harris County Sheriff's Office ITB 250415 for crime scene supplies and forensic collection items (due June 8, 2026, approximately one-year term beginning June 1, 2026); the State of California RFB-IS-27200197 for Shiga Toxin QuikChek diagnostic kits with CBE set-aside consideration (due October 7, 2026); and the District of Columbia Department of Forensic Sciences RK332307 for NGS consumables and reagents (due September 25, 2026). Procurement vehicles include ITB, RFB, and IFB structures with firm pricing, fixed-term contracts typically one year with renewal options, and in several cases set-asides or preferences for certified disadvantaged and local businesses.
