The HR-MAS probe is seen above in close up.  It is a bit more complicated than a normal probe, and the rf connections are not in their normal locations. Starting on the left we see the 2H lock and gradient control connections.  On the front plate are the BB, and spin sensor at the left, and the 1H, thermocouple and heater connections on the right.  The yellow caps cover the air inlets that control the various probe functions such as ejection, drive pressure, and magic angle tip-over.  Underneath the probe are the usual tuning screws, and in gold, the magic angle adjustment.  This should never be touched by users and is set by the technical staff.  There is also a rotor guide tube that is positioned in the bore of the magnet, and a ten position sample holder that sits on top of this.

The photograph above shows the rotor and the associated components that are needed.  The ruler gives a good indication of the size of these parts.  A complete rotor with insert and cap is shown at the bottom left.  The cap alone is above and to the right of this, and an empty rotor is shown standing upright.  The screw is used to insert the insert into the rotor to make a point source of sample - an insert can be seen on the end of the screw.  The silver item is a grip used to remove the caps from the rotors which is a delicate operation, as the tiny fins that spin the rotor are easily rounded off.  The black tool is used to push the insert down to the required level inside the rotor - this ensures that you get a spherical volume of swollen sample.  The circular block is a stand for the rotors to keep them out of harms way when you are preparing the sample.
