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 Kruss Scientific Instruments only for Kruss Dynamic Surface Analyzer DSA100E (contact angle goniometer). The total estimated cost of this effort is
and the estimated period of performance or lead-time for delivery is 12/1/2026. OR
Brand Name Justification:
☐I recommend that NASA, NASA Shared Services Center negotiate only with vendors who can provide the subject brand name from Manufacture Name for Product being purchased. The total estimated cost of this effort is $Dollar Amount and the estimated period of performance or lead-time for delivery is Date . 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. The KRÜSS DSA100E is the only instrument that meets NASA’s full technical and operational requirements for automated, high‑throughput contact‑angle measurement, dynamic wetting analysis, and surface‑energy characterization across the wide range of materials we evaluate, including textiles, composites, polymers, metals, and coated hardgoods. Market research shows that while other manufacturers offer individual capabilities, such as contact‑angle measurement, automated stages, high‑speed imaging, or liquid dosing, no other system integrates all of these functions into a single, turnkey platform without requiring custom programming, manual data stitching, or significant operator intervention.
The DSA100E provides a uniquely complete workflow. Its automated XYZ positioning, recipe‑driven operation, and multi‑liquid dosing allow users to perform complex measurements with one‑click reproducibility, which is essential for a laboratory environment where students, interns, and researchers with varying levels of experience must generate consistent and defensible data. The instrument’s high‑speed imaging captures rapid wetting and absorption behavior that conventional systems cannot
