THE EXTERIOR SURFACE OF THE TITANIUM ROTOR IS FINISHED WITH BLACK POLYURETHANE PAINT. THE ALUMINUM HANDLE AND LID ARE RED-ANODIZED FOR CORROSION RESISTANCE. THE COLOR ALSO IDENTIFIES THE ROTOR AS A HIGH-PERFORMANCE ROTOR THAT USES RED OR BLUE ALUMINUM CAPS WITH MAXIMUM-DIAMETER PLASTIC TUBES. A SLIGHTLY ROUGH OR GRAINY ROTOR SURFACE IS NORMAL. THE SCALLOPED ROTOR BODY MINIMIZES WEIGHT AND REDUCES STRESSES. TWO O-RINGS IN THE LID, MADE OF BUNA N RUBBER, MAINTAIN ATMOSPHERIC PRESSURE INSIDE THE ROTOR DURING CENTRIFUGATION. FOUR SMALL HOLES IN THE LID PROVIDE A TEMPORARY VENT, PREVENTING PRESSURE BUILDUP AND EXTRUSION OF THE LARGE LID O-RING IN THE EVENT OF TUBE LEAKAGE. BECAUSE THE ROTOR IS RELATIVELY HEAVY, IT DOES NOT REQUIRE DRIVE PINS IN THE ROTOR DRIVE HOLE. A ROTOR SPEED EXCEEDING 45,000 RPM WILL BE DETECTED IN INSTRUMENTS WITH EITHER THE PHOTOELECTRIC OR THE MECHANICAL OVERSPEED DETECTION SYSTEMS. AN OVERSPEED DISK IS ATTACHED TO THE ROTOR BOTTON, AND TWO CARTIRDGES ARE INSTALLED IN THE SIDES OF THE ROTOR BASE FOR THIS PURPOSE.
