UNSPSC 41103718: Histology tissue freezing bath

Ultra low temperature mechanically refrigerated bath utilized for the rapid freezing of histology tissue samples with minimal ice crystalization and faster freezing rate than cryostat or cryotome

UNSPSC 41103718 Histology tissue freezing bath is a Commodity code that in recent state and local procurement activity encompasses water and wastewater treatment chemicals, valve components, and related equipment and supplies used in municipal treatment operations — a scope that diverges markedly from the code's nominal focus on laboratory histology equipment. State and local buyers soliciting under this code include municipal water and wastewater departments and county infrastructure agencies. The recent opportunities show purchases spanning powdered activated carbon, liquid aluminum sulfate, sodium chlorite, chlorine gas, sodium bisulfite, soda ash, ferric chloride, and caustic soda for treatment plant operations, as well as industrial valve systems equipped with electric actuators and SCADA compatibility for remote process control in sludge handling and aeration applications. Vendors responding to these solicitations must hold relevant certifications (NSF 60 or NSF 61 for chemicals), demonstrate experience in compliance-driven municipal environments, provide qualified technical support and preventive maintenance programs, and commit to firm pricing and rapid delivery windows.

Recent activity concentrates in Florida and Georgia. The City of LaGrange, Georgia issued an IFB for water and wastewater treatment chemicals (PE74150NONST2026000000025, due June 8, 2026) covering eight chemical lines with estimated volumes totaling over 700 dry tons across the July 2026–June 2027 contract period, with successful bidders required to hold prices firm for twelve months and deliver within two days of request. Broward County, Florida posted an RFI on valve parts and repair services (BLD6232026F23, due September 29, 2026) to evaluate whether DeZurik/APCO valves and maintenance capabilities could be sourced from multiple vendors or sole-source alternatives meeting wastewater permit compliance requirements, with Controls Specialties, Inc. identified as the current exclusive provider. Both opportunities reflect ongoing municipal asset management and operational compliance needs rather than laboratory or histology applications.
