B. Spherical Inserts B

Important Note: The rotor bore and the spacer must be absolutely clean. The lower spacer will be destroyed if it is removed after being inserted into the bore.

1. Spray the "lower spacer" with coolant spray, or dip it into liquid nitrogen, insert

it slightly into the rotor bore and align the rotor axis (figure B.1).

Figure B.1. Spray lower spacer with coolant spray

a) Spray the spacer a second time with coolant spray and press it com-pletely

into the bore. Apply more coolant spray if needed. (figure B.2) or

b) In the case where the spacer fits very tightly, first dip the rotor and spacer

in liquid nitrogen and let them cool. The spacer can now be inserted much

easier into the rotor (figure B.2)

Figure B.2. Inserting the rotor is now easier

2. Insert the sample into the rotor. Screw the cylinder head screw M2 x25 into the

"upper spacer", but do not tighten it! (figure B.3). Use the screw as a handle.

Spray the "upper spacer" with coolant spray or dip it into liquid nitrogen and

press it completely into the bore. Excessive sample will spill out through the

center hole and the thread.

Figure B.3. Spray upper spacer with coolant spray

3. Put the grub screw on a screwdriver and screw it completely into the upper

spacer. (figure B.4)

Figure B.4. Screw grub screw completely

When the assembly is done correctly, the distance between the end of the upper

spacer and the end of the rotor will be 3mm. The short end of the rotor packer

(K8111001) is 2.9 mm long, which will allow you to easily check for the correct fit.

4. 4) Push the rotor cap (KELF) all the way into the rotor. (figure B.5)

Figure B.5. Push the rotor cap into the rotor.
