This document is a NASA Shared Services Center Recommendation and Determination to Solicit from One Source form for procuring a Stokes 412J Microvac area class 1 div 2 group b pump from Edwards Vacuum LLC. The document justifies a sole source procurement for a specialized vacuum pump to replace existing equipment in the SMIRF (likely a scientific research facility) with an estimated cost and a 16-week delivery timeline.

The justification details that the current test chamber uses three Stokes 200 series roughing pumps, and the proposed replacement pump will directly integrate with minimal modifications to the existing facility infrastructure. The document outlines potential impacts of using an alternative vendor, noting that a different vacuum pump would require significant modifications to multiple systems including gas nitrogen purge, structural vacuum lines, MSA gas detection, and physical mounting, which would substantially increase project costs and complexity.
