Freezers, Laboratory, Ultralow Temperature
Definition : Freezers designed to store laboratory products and samples, such as in vitro diagnosis reagents and laboratory tissue and body fluid samples that require very low temperatures, usually from -40 to -90 degrees Celsius (-40 to -130 degrees Fahrenheit). These freezers are usually made with a corrosion-resistant (typically stainless steel) interior, minimizing the risk of adulteration, contamination, and/or corrosion of contents; the internal shelving is appropriate for storage and easy location of laboratory products and samples. Multiuse laboratory freezers include automatic defrost capability, maintaining the temperature in the entire freezing chamber within preestablished limits during the process; they also include sensors, controls, monitors, and alarms for dependable long-term storage following laboratory storage standards. Programmed (e.g., linear rate) or manual control of the freezing rate is possible in most laboratory freezers. A wide variety of ultralow temperature freezer capacities and configurations, including upright and chest models, is available.
