Using this specimen pass - through cabinet is easy. First, make sure the cabinet is properly installed in a wall that's 3 - 6 inches thick. To transfer specimens, open the door on the patient area side, place the specimen inside, and then close the door. The interlocking mechanism will ensure that the other door (leading to the laboratory) can then be opened safely. When it comes to cleaning, simply remove the stainless - steel spillage tray and wash it with mild soap and water. Regularly check the interlocking mechanism to make sure it's working correctly. Avoid using abrasive cleaners on the cabinet, as they may damage the satin finish. Also, ensure that the specimens are properly sealed to prevent spills.
