Water Bath for Microcalorimeters

The National Institute of Standards and Technology (NIST) Guided Wave Electromagnetics Group requires a high‑precision, temperature‑controlled water bath to support RF power calibration activities. The bath must provide exceptional temperature stability (≤0.001 °C) and uniformity (≤0.005 °C) across a 10 °C–30 °C range, accommodate a minimum opening of 6 × 11 in, a depth of at least 16 in, include a mobile cart, and support computer interfacing via GPIB, USB, or Ethernet with SCPI command capability. The vendor must hold an active ECCN and UEI, and deliver the equipment to NIST‑Boulder within 60 days of award. • Quantity: 1 water bath with specified performance criteria. • Required temperature stability: ≤0.001 °C; uniformity: ≤0.005 °C. • Operating temperature range: 10 °C to 30 °C. • Physical dimensions: opening ≥6 × 11 in, depth ≥16 in, mobile cart. • Interface: GPIB/USB/Ethernet, SCPI‑compatible. • Delivery location: NIST‑Boulder, 325 Broadway, Boulder, CO 80305, within 60 days ARO. • Vendor compliance: active ECCN and UEI (SAM.gov). • No on‑site installation or training required per the solicitation.
