UNSPSC 41123204: Microbial quality control QC reference organism

A single microbial organism that is guaranteed traceable back to a known type culture with usually less than five subcultures or passes, which has been lyophilized to be rehydrated and grown for future use as a quality control in multiple method validations in microbiology, and will be utilized as a constituent of laboratory accrediation

UNSPSC 41123204 Microbial quality control QC reference organism is a Commodity code covering the purchase of standardized microorganisms used in laboratory quality assurance and testing protocols. State and local governments procure these reference organisms — typically certified cultures of bacteria, fungi, or other microbes — to validate testing methods, calibrate laboratory equipment, and ensure the accuracy of microbial detection and identification across public health, environmental, and food-safety programs. The organisms are sourced from established culture collections or suppliers and arrive in standardized formats (freeze-dried, lyophilized, or liquid suspension) with documented chain of custody and lot traceability. Buyers include state health departments, state environmental agencies, municipal and county public health laboratories, wastewater treatment authorities, and food and agricultural testing facilities. Purchases are typically small-dollar, routine replenishment buys tied to accreditation standards and laboratory certification renewal cycles.

The source provided contains no recent state or local solicitation activity under this code. Without posted RFP, RFQ, IFB, or ITB notices naming UNSPSC 41123204, no geographic concentration, issuing-body mix, or representative opportunity detail can be extracted. This silence does not indicate dormant demand — reference organism procurement is a recurring operational expense in accredited public laboratories — but rather reflects the code's fit within recurring maintenance and supply budgets that may be procured through standing agreements, cooperative purchasing catalogs, or direct vendor relationships rather than formal open solicitations.
