We disclose a gripper and associated apparatus and methods for delivering
nano-manipulator probe tips inside a vacuum chamber. The gripper includes
a tube; a compression cylinder inside of and coaxial with the tube; and
at least one elastic ring adjacent to the compression cylinder. There is
a vacuum seal coaxial with the compression cylinder for receiving and
sealing against a probe tip. An actuator is connected to the compression
cylinder for compressing the elastic ring and causing it to grip the
probe tip. Thus the probe tip can be gripped, transferred to a different
location in the vacuum chamber, and released there.Samples attached to
the probe tips will be transferred to a TEM sample holder, shown in
several embodiments, that includes a bar having opposed ends; an arm
attached to each opposed end of the bar; one or more slots for receiving
a probe tip; and, each slot having an inner part and an outer part, where
the inner part is smaller than the outer part. The TEM sample holders
just described are inserted into a carrier cassette. A cassette for
transferring one or more TEM sample holders comprises a platform; at
least one bar extending upwardly from the platform; the bar having a
groove for receiving and holding a TEM sample holder. A rotatable
magazine holds one or more probe tips and selectively releases the tips.
The magazine includes a cartridge having a plurality of longitudinal
openings for receiving probe tips and dispensing probe tips.
