Lab cooling and refrigeration products preserve chemicals, samples, and equipment below room temperature. Lab refrigerators and freezers store samples and materials at above- or below-freezing temperatures. Lab chillers and coolers remove heat from lab instruments, processes, and other heat-sensitive applications by circulating coolant. Freeze dryers and accessories remove water and solvents from samples, to preserve materials. Cryogenic equipment stores and preserves samples at ultralow temperatures. Cold storage racks and boxes hold and organize lab samples and containers, such as vials and tubes, within lab refrigerators and freezers. Cold storage locks, alarms, and accessories prevent the unauthorized access of stored lab materials.
