The rotator device is ideal for procedures that require constant or timed rotation, and for procedures requiring a nonstandard speed. A moisture cover is included for RPR syphilis tests. The unit also has a variable speed control with a built-in analog tachometer. The blood rocker gently rocks blood-sample tubes and small vials, assuring damage-free mixing to fragile cell suspensions. The Rocker features a 15-tube capacity that cycles 24 times per minute.
