UNSPSC 23211105: Vacuum impregnation or porosity sealing device

A sealing device that fills all interior spaces, and may or may not leave a thin coating on the surface, depending on the wash rinse performance. The main application of vacuum impregnation porosity sealing is in boosting the dielectric strength of transformers, solenoids, lamination stacks or coils, and some high voltage components. It prevents ionization from forming between closely spaced live surfaces and initiating failure.

UNSPSC 23211105 Vacuum impregnation or porosity sealing device (Commodity) describes equipment used to remove air or moisture from porous materials and seal them, though recent state and local procurement activity under this code shows minimal direct sourcing for the equipment itself. The single recent opportunity posted under the code—Texas Tech University's RFP 2026-1190 for Research and Development Goods & Services, due April 30, 2026—frames the work broadly as laboratory equipment procurement supporting university research initiatives, including microscopes, centrifuges, chromatography systems, fume hoods, and testing equipment. The solicitation does not isolate vacuum impregnation or sealing devices as a primary category but groups them within a larger menu of specialty R&D goods and services. TTU's evaluation emphasizes demonstrated ability to fulfill research needs (50 percent weighting), proposer qualifications (15 percent), compliance with federal and state requirements (15 percent), financial value (10 percent), and value-added options such as local representatives, discounts, e-commerce capabilities, or warranties (10 percent). Vendors must provide three professional client references, comply with TTU's HUB program requirements, maintain specified insurance coverage including $1,000,000 Commercial General Liability, and meet comprehensive IT addenda covering 99.99 percent system uptime, WCAG 2.1 accessibility, NIST 800-53 security controls, and TX-RAMP compliance.

Recent activity under the code appears limited to higher-education research procurement in Texas. Texas Tech University's April 30, 2026 proposal deadline represents the only documented recent opportunity; no other state, county, municipal, school district, or transit authority solicitations appear in the source. Contract pricing remains firm for twenty-four months following execution with potential increases capped at three percent annually thereafter, with an initial term of up to four years plus four optional one-year renewals. Invoices are paid net thirty days through automated payment (ACH or single-use account card) against valid purchase orders. The absence of stated award values or budget ranges and the narrow geographic and jurisdictional footprint suggest that this Commodity code does not drive material state and local procurement volume at present.
