NASA sole-source procurement of a KRÜSS DSA100E analyzer, software, and onsite installation and training

NASA is pursuing a sole-source purchase of a configured KRÜSS DSA100E instrument for research at Langley Research Center. - Buyer and procurement approach - NASA Shared Services Center (NASA/NSSC) is seeking one KRÜSS DSA100E DSA100 Expert Drop Shape Analyzer for use at NASA Langley Research Center. - The notice identifies KRUSS SCIENTIFIC INSTRUMENTS, INC. as the intended sole-source vendor. NASA’s justification says the integrated, turnkey workflow combines capabilities that alternatives do not provide together. - This notice requests capability statements only; quotes will not be considered. Capability statements are due by 10:00 a.m. Central Standard Time on October 30, 2026. - Equipment and included items - One DSA100E analyzer for automated contact-angle measurement, dynamic wetting and surface/interfacial tension analysis, and surface-free-energy calculations. The specified configuration includes a high-speed camera, optical system, dosing equipment, positioning axes, sample stage, LED illumination, frame, and power supply. - One each of software modules AD3221 (Contact Angle), AD3223 (Surface and Interfacial Tension I), and AD62 (Surface Free Energy); one COMPDESK instrument-control module; and one 22-inch HD monitor. - COMPDESK minimum computer configuration: Windows 11 Pro, 64-bit, 16 GB memory, and a 256 GB solid-state drive. - Services and requirements - One onsite installation and training service by a factory-trained KRÜSS expert, including travel and labor, setup, instrument checks, and basic user instruction. The service typically takes four to eight hours; customer sample runs and customized analysis-template work are excluded. - The instrument warranty is stated as two years through the PC manufacturer. NASA software entitlement reporting is due within five business days of the order. - Timing and rationale - Delivery is required within 30 days after receipt of order, with a need-by date of December 1, 2026; the separate justification also gives December 1, 2026 as the estimated delivery lead-time date. - NASA cites integrated automated measurement, multi-liquid dosing, high-speed imaging, and surface mapping as reasons for the sole-source approach, stating alternatives could increase labor, costs, measurement variability, and schedule risk.
