Qiagen BioRobot HAW-00000076-001B Rotor-Edge

The Qiagen BioRobot Rotor-Edge (Part Number HAW-00000076-001B) is a specialized mechanical component designed for use with the BioRobot 8000 or BioRobot 3000 automated workstations. This part serves as a critical interface within the automated centrifuge module of the system. The "Rotor-Edge" refers to the specific precision-machined perimeter plate or adapter ring that secures the rotor buckets or microplate carriers during high-speed rotation. Because these robots are designed for high-throughput DNA, RNA, and protein purification, the Rotor-Edge must be engineered to exact tolerances to ensure perfectly balanced operation and consistent sample alignment with the robotic pipetting arms.

Technically, the HAW-00000076-001B is a revision-specific part, often identified by its robust aluminum or stainless steel construction and integrated sensor-readable markings. These markings allow the BioRobot's internal optical sensors to track the rotor's exact position, ensuring that when the centrifuge stops, the sample plates are oriented correctly for the robotic "gripper" or liquid-handling probes to access the wells. Over time, these edges can experience wear or minor deformation due to the extreme G-forces (often exceeding 5,000 x g) generated during centrifugation cycles; therefore, maintaining the integrity of this part is essential for preventing vibration, which could lead to "robotic crashes" or sample cross-contamination.
