UNSPSC 41103321: Floating body stability measurement apparatus

Equipment that measures the weight center of the gravity in floating body including stability, neutral, unstable and others for the object floating on the liquid surface. Floating pontoon is launched on the water tank to measure the center of floating body, and it measures the change of metacenter height following the slope of the metacenter and the floating body from metacenter height to experiment the stability of the floating body.

UNSPSC 41103321 Floating body stability measurement apparatus is a Commodity code that, despite its technical nomenclature, does not reflect the actual work state and local governments buy under this classification. The recent opportunities posted under this code show minimal direct alignment with floating-body stability instrumentation; instead, the code has been applied to a broad range of laboratory consumables, reagents, chemicals, and analytical equipment used by state health departments, environmental agencies, transportation departments, and municipal water utilities for drinking water quality monitoring, wastewater surveillance, and environmental compliance testing. The scope encompasses standards and consumables such as gas chromatography columns, septa, and UHPLC columns; detector components and ion source assemblies; laboratory reagents including Qiagen wastewater testing kits, synthetic viral assay controls, and capture reagents; magnetic particles for microbiome testing; and laboratory equipment such as sieve shakers and vacuum manifolds. Issuing bodies include state health and environmental departments (Texas Health and Human Services Commission, Colorado Department of Public Health and Environment), state transportation agencies (Texas Department of Transportation), municipalities (City of Arlington, Texas), state natural-resource agencies (Texas General Land Office), and special districts conducting water quality surveillance. The mix reflects heavy participation by state environmental and health agencies, with municipal and state transportation departments as secondary users.

Activity concentrates in Texas and Colorado, with secondary opportunities in California, South Dakota, and Mississippi. Representative recent solicitations include the Texas Health and Human Services Commission's September 2026 IFB for standards, consumables, and instrument parts—GC columns, septa, liners, and detector components used by the Organic Chemistry Group for drinking water analysis, with a historical FY 2026 value between $50,000 and $75,000 and response due October 9, 2026; the City of Arlington's September 2026 annual requirements contract for laboratory supplies and chemicals across Laboratory Services and two water treatment plants; and the Colorado Department of Public Health and Environment's May 2026 sole-source procurements for Qiagen wastewater surveillance reagents ($3.14 million estimated value), Standard BioTools sequencing reagents and service ($2.3 million plus $1 million in reagents), Ceres Nanosciences microbiome capture particles ($3.5 million), and Twist Bioscience synthetic viral assay controls ($2.3 million). The code shows active procurement but limited recent opportunities explicitly matching floating-body stability measurement work, suggesting the code classification may not accurately reflect current purchasing patterns in this category.
