To use this specimen pass - through cabinet, simply place the specimen on the removable spillage tray inside. Open the door from the patient area side, put the specimen in, and then close the door. The interlocking mechanism ensures that only one door can be open at a time, so you can safely transfer the specimen to the laboratory side. When it comes to maintenance, regularly clean the stainless steel surface with a mild cleaner to keep it looking good. You can also remove the spillage tray for a thorough clean. Remember, the cabinet is designed to fit walls 3 - 6 inches thick, so make sure the wall you're mounting it on meets this requirement. Also, avoid using harsh chemicals on the cabinet as they may damage the satin finish.
