1. A method for removing a cap, the method comprising:
providing an apparatus, the apparatus comprising—
a plate having a first side and a second side, wherein the plate comprises a material defining a first aperture of the first side of the plate,
a tightening screw configured to reduce or expand a cross-sectional area of the first aperture, and
at least one pushing screw arranged in at least one second aperture defined by the material, wherein each of the at least one pushing screws comprises (i) a first end extending from the second side of the plate, and (ii) a second end that is extendible from the first side of the plate upon turning the first end;
arranging at least a portion of an NMR rotor cap at least partially in the first aperture, wherein the NMR rotor cap seals an NMR rotor;
turning the tightening screw to reduce the cross-sectional area of the first aperture to secure the NMR rotor cap in the first aperture; and
turning the first end of the at least one pushing screw to extend the second end of the at least one pushing screw from the first side of the plate to apply a force to the NMR rotor with the second end of the at least one pushing screw, wherein the force is effective to separate the NMR rotor cap from the NMR rotor.
