This ultralow-temperature chest is battery powered and mobile

| By Gerald Ondrey

The Mobifreeze M 270 (photo) is said to be the first mobile battery-powered ultralow-temperature chest freezer. Valuable samples or active pharmaceutical ingredients (APIs) can be safely stored and transported from –86 to –50°C. Natural refrigerants are used to provide active temperature control instead of dry ice. The chest freezer has a battery life of 4 h and therefore enables the cold chain to be reliably maintained in intralogistics and for inter-factory transport in road logistics. Cooling is freely adjustable between –86 and –50°C. If the set limits are exceeded, a warning is provided by an acoustic and visual signal. An integrated data logger stores the temperature and alarm data. The freezer is operated via a 4.3-in. touchscreen, whose functionality is also not restricted by gloves. Password-protected user management prevents unauthorized access to configuration parameters. — Lauda Dr. R. Wobser GmbH & Co. KG, Lauda-Königshofen, Germany
