Can I apply a sealing grease to the O-rings of the cell to improve gas tightness?

Yes. However we strongly recommend that you avoid the silicone-containing greases. The silicone may eventually, via your fingers and in others ways, find its way to objects in the high temperature zone, where it will contaminate your samples with silicon and silica. Instead, use a high vacuum quality grease, like Glisseal HV.
