Using this turntable specimen pass box is easy. Simply place your specimens on the turntable. The two - sided access means you can load from one side and unload from the other. To keep it in good condition, clean the stainless - steel surface regularly with a mild cleaner. Avoid using abrasive materials that could scratch the satin finish. When it's time to sterilize, use the cylinder lock to remove the cylinder and place it in a sterilizer or autoclave. Make sure the wall where you install it is no thicker than 7 inches. If the unit rotates too freely, check the bullet catches and adjust them as needed.
