Statement of Work TVHS Purchase of Nitrogen Cryostorage Systems

1.1 INTENT: It is the intent of the Department of Veterans Affairs, Tennessee Valley Healthcare System (TVHS) to purchase three Nitrogen Cryostorage systems for the stem cell lab buildout at the Nashville campus.

1.2 PRICES AND TERMS TVHS Pathology and Laboratory Medicine Service wishes to purchase the following equipment for a new stem cell lab buildout. The space for the equipment will not be renovated until approximately 1 May 2023. This equipment will need to arrive after the space is complete so once awarded, the award may need to be modified to change the date. There is limited space to store equipment currently at either TVHS campus.

2.0 DESCRIPTION/ SPECIFICATIONS/ STATEMENT OF WORK

TVHS, Nashville campus is bringing stem cell processing in-house and will need to purchase equipment for this new buildout. This SOW is for the purchase of three nitrogen cryostorage systems (High Efficiency Freezer Providing Vapor Storage) that must include the below specifications.

· It will need two independent temperature measurement channels

· It needs a fully automated liquid nitrogen level control system that is based on user defined parameters which can be electronically adjusted over the entire level range

· It will need a total of 18 audio/visual alarms are used to alert the user to any potential or developing problems. The alarms include High Temperatures, Low Temperatures, High Level, Low Level, Liquid Usage, Maximum Fill Time, Gas Bypass, Temperature Calibrations, Low Battery, Power Failure, Lid Open and Communication Loss

· Requires one independent port can be used to communicate with other TEC 3000 controllers, a remote PC, serial printer, or other RS485 networks and devices

· Needs a multilevel security system comprised of up to ten user-specific programmable passwords and four security levels that can be customized to grant or restrict personnel access to certain menus and settings.

· Needs to store vital, unalterable, time-stamped data in nonvolatile memory which can be used to assess freezer performance and troubleshoot any problems. The memory must store 30,000 events, an estimated 10 years of storage capacity.

· Must include temperature inlet settings that can vent warm nitrogen gas from the supply line before initiating a fill. This prevents warm gas from entering the freezer space, which helps maintain a stable temperature gradient and increases the efficiency by reducing excess liquid nitrogen evaporation.
