Lab ovens, heating, and refrigeration equipment help ensure proper temperature control for samples and testing. Incubators provide an environment with constant temperature for growing plants and cultures in biology environments. Laboratory heating blankets, tapes, cords, and mantles provide direct contact heating on cylinders, beakers, vials, tubing, and other vessels. Laboratory ovens and furnaces help provide controlled heat for drying, baking, sterilizing, heat-treating, evaporating, annealing, and testing. Lab freeze dryers remove water from samples by bringing them to extremely low temperatures, which helps preserve perishable materials. Lab refrigerators, freezers, and temperature-controlled rooms store samples in specific temperatures.
