Brand Name Requirement: The Government requires the Stirling Ultracold VAULT100 freezer, available through Government Scientific Source, Inc. (GSS), to meet the laboratory’s operational, storage, and performance requirements for preservation of temperature-sensitive biological materials and research samples. The required equipment must provide an adjustable operating temperature range suitable for ultra-low temperature specimen preservation, precise temperature control, and sufficient storage capacity to support laboratory operations and long-term sample retention.

The Stirling Ultracold VAULT100 freezer provides an adjustable operating range from -100°C to -20°C in 1°C increments, allowing precise temperature control necessary for long-term storage of temperature-sensitive biological materials and research samples. The VAULT100 also provides a 795-liter storage capacity capable of accommodating up to 600 standard 2-inch storage boxes while maintaining temperature uniformity at -80°C across multiple positions, supporting sample integrity throughout the chamber.

In addition, the freezer includes features required for laboratory operations and compliance, including a touchscreen graphical user interface, ACT certification, 120–240 VAC compatibility, and insulated inner doors with magnetic latches designed to minimize temperature fluctuation during access events. The Government’s requirement for the identified brand name is based on the laboratory’s minimum technical and operational needs as documented in the supporting acquisition file. Any interested source may submit information demonstrating its capability to meet the Government’s minimum requirements identified in this notice. Responses received will be evaluated to determine whether a competitive procurement is appropriate.
