Section 4 - Sample Chamber Configuration
4.1 Accessing the Sample Space
Before starting the cryostat, check the sample space. Depending on the configuration, there may be
foam inserts to remove before cooling the system down for the first time. Check the Manual Addendum
for instructions specific to your configuration.
NOTICE
Keep sample chamber and surfaces clean
• Always wear sterile gloves when working in the sample chamber to avoid getting oils on the
surfaces.
• Take care not to touch the optical windows on the lid, window assembly, or the internal radiation
shield. Window covers are provided to keep the windows clean.
• Be sure to keep the O-ring seals clean and free from debris. Do NOT set the housing down on an
O-ring seal unless there are protruding bosses to keep it from touching the surface.
• When working inside the sample chamber, use extreme caution not to drop screws down into the
chamber assembly.
Start with the system at room temperature and the chamber vented to atmospheric conditions.
1. Carefully lift the top lid from the sample chamber and place it on the table with the protruding
bosses down. The lid may sit on the bosses without compromising the clean surface inside the
lid.
2. Using two hands, carefully lift the window assembly from the sample chamber. Place the window
assembly on the table so that it rests on a flattened corner (not on a window). This will keep the
interior surfaces and windows clean and free from scratches. The s100 and s200 models include
bosses on the window housing assembly so that it may be place on the table with the
protruding bosses down.

3. Lift the cap from the radiation shield to remove it. Some models have M3 screws securing the
radiation shield lid which must be removed first.
4. Unfasten the M3 socket head screws on each side of the radiation shield. Depending on the
model, there may be 4-8 screws. Lift up and over any sample mount structures to remove.
