Latest Patents

Mark L. Lewis holds a patent for the "Optimum Fixed Angle Centrifuge Rotor." This invention presents a centrifuge rotor and method for gradient density separation. It supports a generally cylindrical volume of sample solution with its axis inclined to the spin axis at an angle optimized for maximum separation efficiency. This design reduces contamination by undesirable centrifugates upon reorientation of the desirable centrifugates. The optimum angle is determined based on the relationship .theta.=Tan.sup.-1 (D/15L).sup.0.5, where D and L are respectively the diameter and length of the cylindrical volume of the sample solution, and .theta. is the angle of inclination. Mark's innovative approach has led to improved outcomes in various applications.
