UNSPSC 41122421: Flask ring stabilizer or weight

Weight or weighted ring placed on the neck of a flask to stabilize it in water baths or applications that place the flask at risk for toppling

UNSPSC 41122421 Flask ring stabilizer or weight is a Commodity code that captures laboratory consumables and specialized reagents purchased by state and local health, environmental, and transportation agencies for water quality analysis, disease surveillance, and materials testing. Recent solicitations under this code show state and local governments buying laboratory supplies spanning analytical reagents for drinking water compliance testing, wastewater surveillance reagents and equipment service agreements, genomic testing controls and capture reagents, field sampling supplies, and precision laboratory equipment such as sieves, balances, and specialized trap assemblies. The issuing bodies include state health and environmental departments (Texas HHSC, Colorado CDPHE), state transportation agencies (TxDOT), municipalities (City of Arlington), and specialized public laboratories. The scope reflects a mix of routine consumable purchasing and sole-source procurements for proprietary equipment and reagents where vendor lock-in or specialized analytical requirements constrain competition.

Recent activity concentrates in Texas and Colorado, with secondary representation from California and Mississippi. The Texas Health and Human Services Commission posted IFB HHS0018026 on September 24, 2026, seeking standards, consumables, and instrument parts for drinking water analysis by October 9, 2026, with historical spend between $50,000 and $75,000. The City of Arlington solicited an annual requirements contract for laboratory supplies and chemicals on August 19, 2026, with response due September 17, 2026. Colorado's Department of Public Health and Environment issued multiple sole-source procurements in May 2026 for specialized reagents and equipment service agreements: Qiagen wastewater surveillance testing reagents and service ($3.14 million estimated value, due May 28, 2026), Standard BioTools genomic reagents and sequencing systems ($2.3 million equipment and services plus $1 million reagents, due May 28, 2026), Ceres Nanosciences microbiome particles ($3.5 million modified value, due May 22, 2026), and Twist Bioscience synthetic viral controls ($2.3 million over four years, due May 22, 2026). Texas Department of Transportation posted IFB 601320000070474 for laboratory equipment and accessories in Corpus Christi on May 6, 2026, with closure April 24, 2026. California solicited Agilent vacuum manifolds and trap assemblies (RFB 26200889) on April 23, 2026, due May 11, 2026.
