Z326-1205 by Hermle is a 12-place fixed-angle (45°) rotor for Hermle Z326 and Z326-K universal centrifuges, holding 12 × 5 mL conical tubes. It reaches 14,000 RPM / 18,624 × g in the Z326 and 15,000 RPM / 21,379 × g in the Z326-K, with ~25-second accel and decel times. It bridges the volume gap between standard microrotors and 15/50 mL conical rotors for cell pelleting, precipitation, and gradient workflows at intermediate volumes.
