UNSPSC 31241810: Gelatin filter

A representative optical absorption filter that is from the colored filters that penetrates the specific wavelength and absorbs the other wavelengths. It is made by forming the thin film on the glass substrate with the organic pigment dissolved in the gelatin solution.

UNSPSC 31241810 Gelatin filter is a Commodity code, but the recent state and local opportunities posted under it do not align with gelatin filtration products. The Texas Comptroller of Public Accounts solicited microscopes and accessories through the Texas Cooperative Purchasing Network (TCPN) as an indefinite-quantity, requirements-type agreement with a September 1, 2026 response deadline; the State of Michigan posted a Notice of Intent for optical lenses and frames with a July 31, 2026 response deadline. Neither opportunity reflects gelatin filter procurement. State and local governments appear to tag laboratory and optical equipment broadly under this code, creating a mismatch between the code's nominal scope and actual buying activity.

The geographic activity is concentrated in Texas and Michigan based on the two most recent postings. The Texas opportunity is a statewide cooperative purchasing vehicle serving multiple state and local agencies, school districts, and educational institutions across Texas with firm fixed-price unit costs for microscope equipment; Michigan's procurement vehicle scope remains unclear from the available summary material. Without additional recent opportunities showing substantive gelatin filter demand, the code signals limited current activity in the category as named, and prospective vendors should verify scope alignment with individual issuing bodies before pursuing opportunities posted under this classification.
