Sample Handling: ManualAll pin types supported: lengths 9 mm to 30 mm
Sample Handling: RoboticsCool Hand Luke
Robotics: More InfoRobot accepts all major pin types (Hampton, Yale, SPINE, etc.) and lengths (10-24 mm) and supports "delayed data collection mode" where data collection runs are deferred to the end of the shift. This robot does not work directly with cassettes because hand-mounting of samples in the mini-hutch is faster than any robot.
