The Angelantoni EKOBASIC series of refrigerators and freezers is used to keep all sorts of samples safe. It can be used with a refrigerator with temperatures of up to 15 degrees Celsius in control or with a freezer that operates at temperatures down to -20. These are stable and will keep the temperature intact while keeping the recovery process running after the door opens. The air is also circulated with forced controls. A key lock and inside lighting system are also used. The shelves can be removed and the energy use levels are very low. This is easy to manage and works with many temperatures and alarms.
