DEVICE: Helmer (00816394021640)

An electrically-powered device intended to be used to store and/or transport blood plasma while keeping it frozen (temperatures of or below -18° Celsius). It typically includes internal shelving for storage and easy location of plasma containers (e.g., bags); a corrosion-resistant (typically stainless steel) interior to minimize the risk of adulteration, contamination, and/or corrosion of contents; forced-air circulation and automatic defrost capability; and sensors, controls, monitors, chart recorders (week-long recordings are typical), and alarms (over temperature, under temperature, and power failure).

A mains electricity (AC-powered) freezer designed for the storage of laboratory products and sample materials, e.g., in vitro diagnostic (IVD) reagents and laboratory tissue/body fluid samples that require extremely low temperatures, usually in the range from -40 to -90? Celsius. It will typically have a corrosion resistant (typically stainless steel) interior minimizing the risk of adulteration, contamination, and/or corrosion of the contents and a shelving configuration appropriate for storage/easy localization of the products. It will typically be programmable, have defrost capabilities, a built-in alarm system to warn against temperature variations, and a recorder to record events.
