About this file
This document is a NASA Shared Services Center Recommendation and Determination to Solicit from One Source or Brand Name, dated November 3, 2026. The procurement is for a Pure Gas Dew Point Transmitter from Michell Instruments, with an estimated lead-time for delivery of 6 weeks. The document justifies brand name procurement rather than full competition based on technical compatibility and performance requirements specific to the government's existing systems.
The justification for single-source procurement centers on the Michell Instruments transmitter's high purity fittings (Face Seal/VCR), which are essential for compatibility with other HGLDS test equipment systems already in use. Market research confirmed this is the only unit available with these specified high purity fitting options. The document emphasizes that use of an alternative vendor's product without high purity fittings (Face Seal, VCR, ConFlat, or AN) would result in contamination of the higher-level MSLDS assembly and cause functional failure. The technical user from AST Technical Management (Office M7-0409:1042) submitted this recommendation.

NASA SHARED SERVICES CENTER
RECOMMENDATION AND DETERMINATION TO SOLICIT FROM ONE SOURCE
OR BRAND NAME
PICK ONE
Sole Source:
☐I recommend that NASA, NASA Shared Services Center negotiate with Vendor name only for Supply or service to be procured. The total estimated cost of this effort is Dollar Amount and the estimated period of performance or lead-time for delivery is Date.
OR
Brand Name Justification:
☒I recommend that NASA, NASA Shared Services Center negotiate with only with vendors who can provide the subject brand name from Michell Instruments for PURE GAS DEW POINT TRANSMITTER.
The estimated period of performance or lead-time for delivery is 6 weeks.
This recommendation is for the acquisition of supplies or services determined to be reasonably available from only one source/only one manufacture. Competition is impractical for the following reasons (please answer the questions below):
1. What are the reasons for soliciting only the suggested source/suggested brand name? Please provide the unique characteristics of the items or services along with the supporting rationale and the market research performed to substantiate your reason for the suggested source/brand name.
Several years of prior use with other HGLDS test equipment systems. It is the only unit found by market survey to have high purity fittings such as Face Seal / VCR.
2. What is the impact to the government if another vendor/brand is used? Include any dollar, schedule, or compatibility impacts if possible.
If it doesn’t have a high purity fitting (Face Seal, VCR, ConFlat, AN), then the higher level assembly (MSLDS) will be contaminated and function properly.
