Freezers, Blood Bank
Definition : Freezers designed to store blood bank products and samples, such as plasma and red blood cells. These freezers are usually made with a corrosion-resistant (typically stainless steel) interior, minimizing the risk of adulteration, contamination, and/or corrosion of contents and internal shelving appropriate for storage and easy location of blood bank products (e.g., blood bags). Blood bank freezers include automatic defrost capability, keeping the temperature in freezing chambers within preestablished limits during the process; they also include sensors, controls, monitors, chart recorders, and alarms for dependable long-term storage according to blood storage standards. Typically, blood bank freezers are available in three different temperature ranges: standard, from 0 to -20 or -30 degrees Celsius (32 to -4 or -22 degrees Fahrenheit); ultralow, from -40 to -90 degrees Celsius (-40 to -130 degrees Fahrenheit); and cryogenic, from -130 degrees Celsius (-192 degrees Fahrenheit) or lower. Programmed (e.g., linear rate) or manual control of the freezing rate is possible in most blood bank freezers. A wide variety of capacities and freezer configurations, including upright, undercounter, and walk-in models, are available.
