Short-Wave Infrared Radiation Open-Top Sample Digestion System

The National Institute of Standards and Technology is issuing a Sources Sought Notice (NIST-MML-26-SS09) to identify vendors capable of supplying a Short-Wave Infrared Radiation Open-Top Sample Digestion System, with responses due by August 21, 2026. No set-aside is anticipated. NIST has not yet determined its acquisition strategy and states that identification of COLDBLOCK Technologies in this notice does not constitute a commitment to sole-source procurement.

The system must be a multi-channel (10–20 channels) open-air digestion block designed for operation inside a laboratory chemical fume hood, controlled by a digital unit with integrated software for multi-step digestion programming accessible via tablet, laptop, or desktop. The system must employ focused short-wave infrared radiation technology coupled with an upper cooling zone to prevent volatile element escape. A fully compatible external recirculating chiller is required, with temperature range of −5°C to 25°C, minimum cooling capacity of 300 watts at 20°C, pump flow rate of 10–20 liters per minute, and reservoir volume of 3–5 liters. The contractor must supply a starter accessory kit including test tube racks, transfer trays, hydrofluoric acid-compatible digestion tubes (Teflon-based), and one spare infrared heating lamp with minimum 4,000-hour runtime rating.

Electrical compatibility must support dedicated single-phase 208–240 volt AC, 50/60 Hz, 30 ampere power with NEMA 6-30 plug configuration for U.S. facilities. Official CE and/or CSA safety certifications are required. On-site installation during normal business hours (8:30 a.m.–5:00 p.m. Eastern Time, Monday–Friday) must include unboxing, assembly, demonstration, and trash removal, plus training for up to four personnel covering system safety, method programming, maintenance, calibration, and troubleshooting. Responses should address company information, feedback on draft requirements, product specifications with country of origin, pricing, regulatory compliance, and existing governmentwide contract vehicles.
