Attachment III – Statement of Work

BACKGROUND

The National Institute of Standards and Technology (NIST) Storeroom and Warehouse is a

11,500 square foot facility, with a 2,700 square foot sales floor, located in Building 301 on the

NIST Gaithersburg Campus. The Storeroom is a part of the NIST Facilities Services Division.

Their mission is to the best customer service plus the highest quality, variety and convenience at a competitive price.

The NIST campus has a fleet of approx. 100 NIST-owned Liquid Nitrogen Dewars in various sizes and ages that range from 25L-300L. The NIST Gaithersburg Main Storeroom is responsible for picking up, filling and delivering the various Liquid Nitrogen Dewars to the end users that use Liquid Nitrogen throughout the NIST Gaithersburg Campus.

Recently, NIST upgraded the NIST owned Liquid Nitrogen Dewar fleet to a universal sized

180L Liquid Nitrogen Dewar. These have quickly become the dewar of choice for most users within the NIST Gaithersburg community, as they allow for faster pick-up, delivery and filling as well as including a number of safety features.

PURPOSE

NIST is looking to purchase additional 180L Liquid Nitrogen Dewars, meeting the following specifications, to add to its existing fleet. All equipment shall be new and not refurbished and must become the property of the government.
