Micromeritics ACCUPYC II 1345 User Manual

CHAMBER CAP O-RING
The cell chamber cap contains an O-ring that requires routine maintenance. The chamber cap O-
ring should be greased at the beginning of each period of use.
Fine fibers and particles between the O-ring and its sealing surfaces can cause leaks, as can
scratches or cuts in the O-ring or in the metal surfaces.
GREASE THE CHAMBER CAP O-RING
1. Turn the chamber cap counter-clockwise and lift it from the chamber.
2. Place the chamber cap on a clean surface with the O-ring side exposed.
3. Use a small drop of Dow Corning high vacuum grease (or equivalent).
4. Distribute the grease evenly and completely around the O-ring groove.
5. Replace the chamber cap.
6. If recalibrating the pycnometer, allow the pycnometer to warm up for 30 minutes before cal-
ibrating.
