UNSPSC 41171606: Differential culture medium

In this classification, a Differential culture medium connotes a device used that consists primarily of liquid or solid biological materials intended for medical purposes for the cultivation and identification of particular organisms. US FDA regulates Differential culture medium under 21 CFR 866.2320 and under FDA product code JSH.

UNSPSC 41171606 Differential culture medium, a Commodity code, covers growth media formulated to differentiate between microbial species or isolates based on biochemical characteristics, metabolic end products, or selective inhibition — the kind of laboratory consumables state and local health departments, public health laboratories, and university research facilities rely on for pathogen identification, microbial screening, and clinical diagnostics. State and local procurement under this code typically includes chromogenic media, selective and differential agars, and enrichment broths used in clinical microbiology workflows, quality assurance testing, and disease surveillance operations. Issuing bodies span state public health laboratories, county health departments, university laboratory systems, and research institutions; repeat buying tends to concentrate among larger state departments of health and regional laboratory networks that maintain standing demand for routine culture and confirmation protocols.

The recent opportunities block contains no entries for this code, indicating little or no publicly posted state and local procurement activity under UNSPSC 41171606 over the period reflected in the source data. This does not signal that state and local agencies have ceased purchasing differential culture media — they remain routine laboratory consumables — but rather that available solicitation records do not show tagged opportunities under this specific code at this time. Buyers may be sourcing through blanket purchase orders, cooperative purchasing vehicles, or standing master agreements with laboratory suppliers that do not generate fresh RFP or IFB notices, or may be tagging such purchases under related consumables codes.
