Ion Gauge Calibration Service Heater Enclosure

The National Institute of Standards and Technology (NIST) is seeking quotations for an Ion Gauge Calibration Service Heater Enclosure to upgrade their existing ionization gauge calibration service facility. The procurement requires a specialized vacuum bake-out enclosure with 4-8 removable side panels capable of withstanding temperatures up to 200°C, featuring heating elements, pneumatic valve ports, and a PID controller for temperature control with ramp rates between 0.1-1°C per minute. The enclosure must accommodate a hexagonal chamber with specific dimensional constraints including 51 inches in height and 22mm radius, incorporate 2-inch maranite insulation, and provide routine access without full disassembly. Evaluation will be conducted based on technical capability, relevant experience, and proposed price, with technical factors weighted more heavily than price considerations. The government requires a four-volume quotation submission including technical specifications, relevant experience from the past five years, firm-fixed-price quotation, and terms and conditions, with all quotations due by July 7, 2025, at 12:00 PM EDT.

This procurement is designated as a total small business set-aside under NAICS code 335932 for Noncurrent-Carrying Wiring Device Manufacturing, with no incumbent contractors identified in the solicitation materials. The contract involves a single line item for one heater enclosure unit with a delivery timeline of 12 weeks after order placement, followed by a 30-day government inspection and acceptance testing period. Performance will occur at NIST's facility in Gaithersburg, Maryland, where the enclosure will be installed on an existing support table with pre-installed chamber and pneumatic valves. Payment terms specify 100% compensation after successful installation and acceptance by the NIST Technical Point of Contact, with temperature measurement requirements including RTD or K-type thermocouple sensors providing 0.1°C resolution and better than 2°C accuracy. While no specific contract value is disclosed, the technical complexity and specialized nature of the equipment suggest a substantial procurement value for this laboratory equipment acquisition.
