UNSPSC 41141533: Thiosulfate standards

In this classification, this entry connotes a standardized formulation of Thiosulfate used to conduct Anion tests.

UNSPSC 41141533 Thiosulfate standards is a Commodity code encompassing chemical reference materials and quality control standards procured by state and local health, environmental, and forensic laboratories for analytical method validation, instrument calibration, and compliance testing. State and local governments buy these materials as consumables supporting drinking water safety analysis, food and dairy testing, drug forensics, environmental monitoring, and public health surveillance. The issuing bodies include state health departments, state public safety agencies, county forensic laboratories, and county environmental health offices. Texas agencies dominate recent activity, with the Texas Health and Human Services Commission and Department of State Health Services soliciting repeatedly for standards and quality control materials used in organic chemistry and microbiology analysis, and the Texas Department of Public Safety procuring immunalysis reagents for substance testing.

Recent opportunities span Texas, Florida, Illinois, and New York. The Texas Health and Human Services Commission issued IFB HHS0018026 on September 24, 2026, due October 9, 2026, requesting standards, consumables, and instrument parts including GC columns, UHPLC columns, and detector components for drinking water analysis, with historical annual spend of $50,000 to $75,000. The same agency solicited lab supplies for food, water, and dairy testing under IFB HHS0017881 in August 2026, requesting quality control test kits and bacterial strain kits compatible with Biomerieux instruments, valued between $25,000 and $50,000 annually. The Texas Department of Public Safety issued IFB 405-26R0008445A in July 2026 for Direct ELISA testing kits and phosphate-buffered saline solution used in forensic drug analysis. Pinellas County, Florida, procured certified reference drug standards through ITQ 26-0305-ITQ in April 2026 for the Forensic Laboratory's toxicology and seized drug analysis units, funded through the Paul Coverdell Forensic Sciences Improvement Act with $49,034.00 designated for equipment and supplies. Rockland County, New York, sought radon measurement devices and laboratory analysis services through RFP RFBRC2026044 in July 2026. Illinois established a joint purchase master contract for mosquito testing equipment (RAMP System test kits) through sole source procurement in May 2026.
