Attachment 3 - Brand Name Justification.pdf

This is a Single Source Justification form for a simplified acquisition to purchase one Labconco brand fume hood assembly for the B-21 Low Observable Maintenance facility at Ellsworth AFB, SD. The requirement is being managed by the 28th Contracting Squadron under purchase request F1V0A65027A001.

The justification specifies the need for a Labconco 4' Protector XStream Laboratory Hood that operates on 100-115V, 50/60Hz, with a 48" Standard Base Cabinet, 14" deep Filler Panel, and SpillStopper Work Surface measuring 4'w x 36"d with no cutouts. While Labconco is a large business, market research identified twelve small business resellers, with four confirming their ability to provide the equipment. The B-21 facility is currently the only known facility requiring this fume hood installation. The Contracting Officer determined on February 20, 2025 that only a single source is reasonably available for this procurement.
