Using the Bobrick B - 505 cabinet is easy. Just open the doors with the cast aluminum pull knobs and place your specimens inside. It's suitable for urine, fluid, and tissue cultures. If there's a spill, simply remove the spillage tray for cleaning. When installing, make sure the rough opening measures 11 - 1/2 inches in width and 10 - 7/8 inches in height, and the wall thickness is between 3 and 5 - 3/4 inches. To maintain it, regularly wipe the satin - finished surfaces with a soft cloth. Avoid using abrasive cleaners as they may damage the smudge - resistant finish. Also, check the spring - loaded doors periodically to ensure they're closing properly.
